2017 IBS 1000-Yard Benchrest Nationals
Report By Boyd Allen
On September 1-4, the IBS held its 2017 1000-yard Benchrest Nationals at the Whitehorse Shooting Center in Peeltree, West Virginia. There was a great turn-out this year, with 118 entries in Light Gun Class (17-lb limit, 5 shots per target) class and 107 shooters in Heavy Gun Class (Unlimited weight, 10 shots per target). The conditions this year were challenging to say the least, with rain storms, spiraling winds, and fog. In fact, rain and fog on Saturday (with cancelled relays) caused the Nationals to be extended by one day through Monday, September 4th. What’s more, of the 107 shooters listed in the Two-Gun Overall results who actually shot both guns, there were dozens of DQs. (Yes, the wind was a bit tricky at this year’s Nationals.)

Congratulations to the “top guns” at the Nationals: Edward Kenzakoski (Two-Gun Overall Champion), Mike Gaizauskas (Light Gun Overall, plus LG Score Agg), and Mike Brennan (Heavy Gun Overall, plus HG Score Agg). Group Agg winners were Richard Schatz for LG, and Charlie Lentz for Heavy. Two ladies also deserve mention. Sally Bauer shot the smallest group of the match, a 1.923″ 5-shot group in LG — that’s 0.184 MOA! Ruth Edwards drilled a 2.104″, also mighty impressive. Nice shootin’ ladies…

White Horse Wind and Weather Factors — and Topography
The firing line for the 1000-yard range has a covered structure with 14 well-spaced masonry benches with block bases and cast concrete tops. Facing southwest, the firing line is above the land between it and the target butts, which are at the head of a canyon. There is a low area with trees on the left with an elevated flat area on the right.

This topography create unpredictable wind patterns that can change rapidly with no warning. Those changes can wreak havoc with competitors’ groups and scores. The wind direction at the targets can be opposite that at the firing line, with the result that a let-off down range not only carries the penalty of making a hold-off incorrect, but because the wind at the firing line can continue, adding the additional penalty of a reversal. This was the common cause of disqualifications, which were numerous at this year’s Nationals.

Delay Caused by Fog and Rain
On Saturday, rain and fog delays, caused the match to be extended through Monday. The rules dictate that if a full match cannot be finished because of weather, then all of the day’s results are discarded. This meant that even those shooters who completed their relays on Saturday had to shoot them over — hence another day was added to the event. Because of the prospect of worsening conditions on Saturday afternoon, even though there was daylight left, the decision was made to extend the match through Monday.

Profile of 2017 IBS 1000-Yard National Champion Edward Kenzakoski

Commenting on his performance at the Nationals, Ed said modestly:
“I didn’t shoot really good. I just shot better than them other guys.”

Winning Hardware (with a 110-lb Heavy Gun)
Notably, Ed does all of his own gunsmithing, and he built his Championship-winning rifles. Both guns featured 1:11″-twist, 30″ Krieger barrels. (LG: 1.250″ shank and .950 muzzle; HG: 2″ contour untapered). Ed’s Light Gun has a BAT action, no barrel block, Jewell trigger, and McMillan Tooley MBR stock. His Heavy Gun boasts a 10″-long BAT action in a two-piece aluminum stock with barrel block. That HG beast weighs 110 pounds! Both of Ed’s rifles (light and heavy) wore Nightforce 12-42x56mm BR scopes.

Winning Numbers
To win the Two Gun Overall, Ed posted 137 LG Score, 262 HG Score, and 399 Two-Gun Score Agg. His Group numbers were: LG Group 5.659, HG Group 7.483, Two-Gun Agg: 6.571.

Winning Loads and Reloading Methods
Both rifles are chambered in 300 WSM. Ed shoots 210gr Berger VLDs (sorted every way possible), with Norma brass, Hodgdon H4350 powder, and CCI BR2 primers. For the two guns he used very different seating depths — barely touching for the HG, 0.100″ jump for the LG. He said that it takes him a full four days to load the ammunition for both rifles for a match. Yes, he weighs primers, and he even passes his bullets through a .309 bushing.

No Dark Horse at White Horse — Kenzakoski is a Proven Winner
One shouldn’t be surprised at Edward Kenzakoski’s success. Ed really cleaned up at Williamsport this year, winning one 6-match Aggregate and two 10-match score and group Aggregates. He also established a new Williamsport club Light Gun record of 3.2″.

Record-Setting Asymmetry
In 2016 Michael Gaizauskas set the current 1000-yard IBS Heavy Gun (10 shot) group and score records. He set those records with the rifle on the left (below), then chambered in 6.5×47 Lapua. In this match, Mike won LG Group and LG Overall with the rifle on the right as chambered in his own 7mm short magnum wildcat. Mike designed and built both these distinctive assymetric stocks.

White Horse Shooting Center Facilities, Organization, and Location
The 1000-yard range used at the IBS 2017 Nationals is part of a large shooting facility run by Whitehorse Firearms Outdoor Education Center in cooperation with the West Virginia Division of Natural Resources. White Horse is located off of Route 20 near the small community of Peeltree, WV. The nearest town of any size, ten miles to the south, is Buckhannon, WV, which has about 5600 residents.

White Horse Geography and Climate
The White Horse range is set in wooded hill country, with lots of creeks and some smaller rivers all kept green and running by an annual rainfall of about 48 inches and about the same for snowfall. To my eyes it is beautiful county, pleasingly rural and lush, in marked contrast to where I live where every plant must be served by some sort of irrigation.

Amazing See-Through Suppressor Video from Smarter Every Day

Suppressor silencer acrylic see-through Soteria Thunder Beast Arms Zak Smith Smarter Every Day

Popular YouTube Channel Smarter Every Day recently released a fascinating video featuring rifle suppressors with see-through acrylic sleeves. The team filmed shots through the suppressors using ultra-high-speed (110,000 frame per second) cameras. When played back in super-slow-motion, you can see the flame propagate through the suppressor and the bullet move through each baffle before it exists the muzzle. Notably, you can see different internal flame effects depending on the baffle design. Watch the results in the video below — it’s mesmerizing:

The Science of Suppressor Design

Commentary by Zak Smith of Thunder Beast Arms Corp.

Suppressor silencer acrylic see-through Soteria Thunder Beast Arms Zak Smith Smarter Every DayThe high speed transparent silencer video is pretty neat. It certainly demonstrates, to some extent, the violence that happens inside centerfire rifle suppressor when firing.

At Thunder Beast Arms Corp. we have carefully studied the forces/pressures operating inside suppressors. The “uncorking” pressure when the bullet exits the muzzle is typically in the 8,000 to 15,000 psi range, but some combinations of cartridge and barrel length can extend this up to the 25,000 psi range. Job #1 of a suppressor designer is to build a suppressor that won’t explode. Job #2 is to build one that quiets down the muzzle report significantly. Doing that well, with the minimum amount of material, is the tricky part.

Suppressor design is both art and science, and we approach our R&D from three sides: experience, experimental testing, and computation.

There are a lot of opinions about how to design a quiet suppressor. Many of these are based on preconceived notions of how suppression “should work”. These theories may or may not work when built and tested in the real world. Where the rubber hits the road is experimental testing. I would say that a majority of knowledge about “How to design a quiet suppressor” comes from building hundreds or thousands of prototypes and testing them with good equipment in a cogent experimental process. Some of those theories pan out, but many of them do not.

Scientific Software Aids Design
We have also made a large investment in computation fluid dynamics (CFD) and finite-element analysis (FEA) software and use it in addition to other computer-model analysis to look at the physics that occurs inside the suppressor. This type of analysis gives information about material effects that is pretty much impossible to get any other way. Even so, the computer cannot tell you how to design a
suppressor, and the results must always be checked and compared to reality.
