Sunday GunDay: .300 WSM Pending 1K World Record Heavy Gun

This Sunday we feature an impressive .300 WSM Heavy Gun shot by a superb long-range shooter. With this rig, at age 83, Arizona benchrest ace Charles Greer drilled a remarkable 2.862″ 100-10X group, beating all known 1000-Yard HG 10-shot records on the books. If this record is approved (which is likely), Greer’s .300 WSM can rightfully be hailed as the most accurate 1000-yard gun in history.

This would be an excellent 10-shot NBRSA Heavy Gun group at 600 yards, but this target was shot at 1000 yards by Charles Greer (aka “chuckgreen” on AccurateShooter forum) on February 13, 2021 at an NBRSA Match in Arizona. Chuck was shooting his .300 WSM Heavy Gun with Borden action, Krieger barrel, and Berger 220gr Hybrids. The event was hosted by the Sahuaro 1000 Yard Benchrest Club, at Three Points Range, outside Tucson, Arizona. Though it is pending final approval, it appears this is the smallest 10-shot Heavy Gun group ever shot, anywhere, at 1000 yards, and it was centered for a 10X. That’s doubly impressive when you consider that Charles Greer achieved this at age 83! Yes “Old guys rule”!

Amazing 100-10X 2.642″ (unofficial) 10-Shot Group at 1000 Yards.

This group is perfectly centered for an amazing 100-10X score. The group was range measured at 2.642 inches. For reference, the 1000-yard X-Ring is 3.00″ in diameter. The “X” itself is about 1.2″ tall. Pending final verification, this amazing target should shatter two NBRSA records. This handily beats the current single target HG score record of 100-6X held by Bill Schrader since 2005, and the single target HG group record of 3.650″ held by Tim Height (2019). For comparison, the current IBS 10-Shot 1000-yard HG group record is 2.871″ by Michael Gaizauskas from 2016. So it appears that this may be the smallest 10-shot group ever shot in competition in history. And from what we can determine, this is the first potential HG size record that also has a 100 score with TEN Xs.

Because shots are not marked in this discipline, this stunning group was a surprise to Greer: “I had no idea that I was shooting a world record target until I went back to the pits after my relay. Just as well. If I’d seen nine rounds in the X on the target, staying steady [for the last shot] would have been challenging….”

Forum member “Tom” (2016 IBS 1000-yard Nat’l Champion and holder of several IBS 1000-yard records) unofficially measured Greer’s 1K group at 2.680 inches (0.256 MOA), using Ballistic-X software. Awaiting final group measurement by the NBRSA Long Range Committee, as currently measured, this target is just under existing IBS and Williamsport 10-shot HG 1000-yard records: The current IBS HG 1000-yard group record is 2.871″ held by Michael Gaizauskas. The current Williamsport HG 1000-yard group record is 2.815″ held by Matthew Kline.

Benchrest Shooting — Sport for All Ages
Charles Greer reminded us that even senior citizens can succeed in benchrest competition: “One of the benefits of benchrest shooting is that it is a sport accessible to us even as we age. I cannot run and gun anymore like I used to do in IPSC and IDPA but as long as I can get my body and my equipment up to a bench, I can still be very competitive. That is not possible for us old guys in most sports and shooting disciplines. As I am ‘only 83′ I am hoping to squeeze a few more years of competition out of the old body before I have to pack it in for good.”

Charles is thankful for what he has achieved in this sport over many decades: “The Shooting Gods have certainly smiled on me from time to time during my brief shooting career and for that I am incredibly grateful.”

This target may also be the smallest 1K 10-shot group ever shot in competition, in ANY Class. In 2014, Jim Richards fired a 10-shot, 2.6872″ Light Gun group under Williamsport Rules at Deep Creek Range in Montana. However, Jim’s record small group was NOT centered in the 10-ring and it appear that Greer’s group could measure smaller. [Editor: Charles is no stranger when it comes to 1000-yard records. Charles is the current listed holder of two NBRSA 1000-yard score records: 3-Target HG Score: 294-8X (2010); 6-Target 2-Gun Score: 441-13X (2010).]

100-10X at 1000 — This May Be a First
After looking at all the 1000-yard records from different organizations, it appears that Greer’s 100-10X score could well be a first! And it may be many years before another 100-10X score is ever shot in competition.

Arizona’s Three Points Range is known for its windy conditions. So much so that small groups are not common in match reports. 6mm cartridges that are commonly shot at other 1000-yard benchrest competitions are rarely shot at Sahuaro 1K BR Club matches. The bigger calibers dominate here.

Upside-Down (Wider Base) Stock Rudder Improves Rifle Tracking

Greer has done something clever with his McMillan/Wheeler benchrest stocks. He has flipped over (inverted) the adjustable metal rudder (or keel) that runs on the underside of the buttstock. This provides a wider, flat tracking surface. The inverted rudder runs in a special sandbag on a Walhstrom mechanical rest. NOTE: Mechanical rear rests ARE legal for BOTH Heavy Guns and Light Guns under current NBRSA rules (see page 24). Shown at right is Greer’s Light Gun, but his Heavy Gun has the same system.

Charles explains: “Both my LG and my HG are of the same configuration except for additional weight in the stock of the HG. I decided to do this so that I would not need a separate rest system for each gun which saves on expense and makes it much easier to switch the LG out for the HG during competition. No need to change rest systems and re-align everything. Both of my stocks are McMillan/Wheeler LRB models with the adjustable rudder that can be repositioned horizontally to improve tracking. The rudder has a 3/4 inch-wide base that is usually fit into an Edgewood gator bag with a flat top. I did not like the way the rifle tracked with this set up and wanted something more solid and stable.

So I found that if I turned the rudder upside down and re-installed it that way on the stock, using the same screws and holes, the top of the rudder when turned down provided me with a base 1.5″ wide with a 1/4″ rail on each side. I got a Wahlstrom mechanical rear rest and had a custom Edgewood front bag made for it with a 1.5″ separation between the ears. The rail tracks perfectly in the bag and I can tighten the ears to make it quite solid and steady. I have noticed a huge improvement in tracking with this set up. I am still refining this arrangement but plan to continue using it on both rifles. I have never seen this done and was thinking maybe your readers would be interested.”

Questions & Answers with Charles Greer

Hall of Fame short-range shooter Gary Ocock interviewed Charles Greer. This interesting Q&A dialog covers shooting styles, equipment selection, recoil management and other notable topics.

Q: Tell us about your rifle, accuracy standards, and choice of calibers and bullets for the 1K game.
Greer: I set up two rifles, Light Gun and Heavy Gun. Both will shoot 100-yard 5-shot groups in the high ones and low twos. In Arizona I want a heavy, high-BC bullet in both guns to buck the wind and want to keep the ES under 10 FPS. I’m finding .300 WSM with Berger 220 LRHT bullets and a 4 groove Krieger barrel will provide the performance I need, and I shoot this round in both rifles.

Q: Explain your rest set-up, tracking, and recoil management. And how fast do you typically shoot your strings of fire?
Greer: I am using a Sinclair Competition Front Rest along with a mechanical rear rest, both with Edgewood front bags, to give me the stability necessary to provide consistent tracking even with these relatively high recoil rounds. Almost perfect tracking and consistent return to battery in the same spot is necessary to get a record string off quickly and smoothly. I try to get my strings off in a time of between 6 and 10 seconds per round depending on conditions. Any faster and I get sloppy.

Q: What were conditions like when you shot that amazing 10-shot group?
Greer: On the day I shot the record-pending target I had the first relay. There was wind but it was light, maybe 4-5 mph and seemed steady. The flags were about halfway up to horizontal and seemed to be holding that way. My procedure is to shoot 5 sighter rounds, two to adjust my initial round on paper to the X-Ring and then three more during the last minute to check for changes in the wind. If these last three rounds stay in the Ten Ring it is usually a sign that the wind may be steady enough for me to shoot a good group. On the “record” day the last three sighters were right in or near the X-Ring and when the record target came up I quickly but carefully dumped my 10 rounds holding the scope dot right on the X. The wind apparently held absolutely steady, and I got the result you see on the target.

That is my normal shooting technique. I pretty well know during the last minute of the sighter period whether a good group will be possible. If each of my last three sighters ends up inches away from the X in different directions, I know the wind is shifty and a good group on that target is unlikely. I adjust the last sighter to the X and then dump the string the same way just hoping the wind may hold for a minute or so. Sometimes it does, but often not so much.

During the record strings there is no way to know where the rounds are going. They are not marked, and the holes cannot be seen through the scope at that distance. The 1K flags are big and heavy and not very indicative of minor wind changes so I do not try to hold off or change my point of aim unless a flag completely reverses direction during a string. I’ve found that over the years adjusting my point of aim to the X after the last sighter and then dumping my strings gets the best results overall.

Q: What is your highest shooting accomplishment so far?
Greer: Well, the highest accomplishment (if one can call it that) would have to be this 100-10X target. This may end up being the best 10-shot target ever shot in a sanctioned match. 0f course, there is a tremendous amount of luck involved in this coming together but I certainly am pleased.

I had set four NBRSA world records when I was shooting previously: Light Gun Agg in 2008, and all three possible Highest Three Target Score records in 2010, two of which still stand. The first was probably the most satisfying as was my performance in the 2010 Nationals where I placed high in several categories and was Heavy Gun Champion for Score.

Q: Who do you attend matches with?
Greer: During the last year my son, Brian, has become my match shooting companion. We go out together every month. Brian was able recently to purchase the great 300 Ackley HG that I competed with and set world records with in 2010. I sold the rifle to a friend who never shot it and it found its way back into our family. Brian is now becoming a serious competitor.

Q: What are your future shooting goals?
Greer: To keep on shooting our local match each month and to try to get to the Nationals once or twice more before I get too damn feeble. And to be able to see my son take my place as a regular winner when I can no longer compete.

Q: Is there any advice you would like to share with new shooters?
Greer: Make a commitment to excel at whichever discipline you choose. Get the best equipment and components that you can afford and consider each match a learning experience. At some point anything that can go wrong will go wrong and one must learn from these mistakes. Most importantly, be patient and keep coming back. In Arizona good shooting conditions are rare. You gotta be “in it to win it”. If you show up at every match you can attend eventually a great condition will appear on your relay and you will have a chance to shoot a spectacular score.

Q: What is your shooting background?
Greer: I started shooting rabbits as a kid in the Mojave Desert, trained on various firearms in the military in the fifties and sixties and over the years hunted birds and large game and played with various handguns. In 2005 I moved to Tucson from Mexico the first time and, looking for an activity, started shooting IDPA and IPSC pistol matches at Pima Pistol Club. Shortly thereafter I bought a .308 Savage tactical rifle and got interested in shooting for accuracy. One thing led to another and before long I bought a better Savage varmint rifle in .300 WSM and started shooting the 1K match at Tucson Rifle Club at Three Points around 2007. I kept upgrading my equipment, started winning matches, set some world records.

After the 2011 NBRSA Long Range Nationals I felt rather burnt out on shooting. I sold all my guns and equipment and headed South looking for perhaps one more adventure. I found some but they did not include shooting as South of the border folks tend to shoot back when they hear anything go bang. I returned to Tucson in May of 2019, built a couple of new rifles, and got involved again in the monthly Sahuaro match where the most recent world record target was shot. I would like to resume shooting the NBRSA Long Range Nationals. Will not be ready this year but probably will in 2022.

Q: Have you tried other disciplines at different ranges?
Greer: I have only competed in Long Range, mostly 1000 yards but 600 yards a few times at the Nationals. I would like to try shooting “Score” and there is a monthly match at our range. May try it if I can get an appropriate rifle.
