Judging by the calls I’ve had through the years, I think some shooters might be placing too much importance on Ballistic Coefficient (B.C.). The best example of this comes from a call I had one day. This shooter called wanting the ballistic coefficient of one of our Sierra bullets. After I told him he seemed a little disappointed, so I ask him what his application was. Long range target, deer hunting in the woods? Talk to me.
As it turned out, he hunted deer in open timber. He very rarely shot beyond 100 yards. I pointed out to him that, under 200 yards, B.C. has little impact. Let’s compare a couple of bullets.
Let’s look at the trajectory of a couple of bullets and see how they compare. The .30 caliber 180 grain Round Nose #2170 RN and the 180 grain Spitzer Boat Tail #2160 SBT. The round nose has a B.C. of .240, while the SBT is .501. Starting both bullets out of the muzzle at 2700 FPS [with a 100-yard ZERO], at 200 yards the #2170 RN impacts 4.46″ low while the #2160 SBT impacts 3.88″ low. That’s a difference of only 0.58″ in spite of a huge difference in Ballistic Coefficient. If we compare out at 500 yards, then we have a [significant drop variance] of 14.27″ between these two bullets. [Editor: That difference could mean a miss at 500 yards.]
Distance to Your Prey is the Key Consideration
In a hunting situation, under 200 yards, having a difference of only .58” isn’t going to make or break us. But when elk hunting in wide open spaces it could mean everything.
The next time you’re choosing a bullet, give some thought about the distances you will be shooting. Sometimes B.C. isn’t everything. If you have any questions, please give the Sierra Bullets technicians a call at 800-233-8799.

Team USA Olympian and ISSF World Cup Winner SFC Michael McPhail is one of the world’s best smallbore rifle shooters. He is also an avid hunter, who enjoys harvesting game with centerfire rifles. In this excellent short video from the USAMU, McPhail shows how competition shooting positions can be adapted for hunters. McPhail shows how well-established positions can provide a more stable platform for hunters in the field. That can help ensure a successful hunt. McPhail demonstrates three positions: kneeling, supported prone, and sitting in a tree-stand.
Watch SFC McPhail Demonstrate Positions for Hunters (Good Video):
McPhail first demonstrates the kneeling position. Michael notes: “I like kneeling. It’s a little bit of an under-utilized position, but it’s almost as stable as prone. It allows you get up off the ground a little bit higher to [compensate for] vegetation. For kneeling start by taking your non-dominant foot and put that towards the target, while at the same time dropping down to a knee on the dominant leg. At the same time … wrap the sling around wrist and fore-arm, lean slightly into the target and take the shot.”
McPhail shows a nice “field expedient” use of your backpack. He shows how the basic prone position can be adapted, using the pack as a front rifle support. McPhail recommends pulling your dominant (strongside) leg forward, bent at the knee. According to Michael, this takes pressure off the abdomen, helps minimizes heart beat effects, and helps with breathing.
Last but not least, McPhail shows some clever treestand tricks. McPhail recommends a position with your weakside leg pulled up and firmly braced on the front rail of the treestand. You can then rest your support arm on your leg. (That would be the left arm for a right-handed shooter). This provides a rock-solid position when shooting from a stand. The second half of the video shows how this works.

This great resource provides a detailed history of popular cartridges, along with a discussion of these cartridges’ hunting and target-shooting uses. There are currently 26 Cartridge of the Month articles, the latest featuring the mighty .500/.416 Nitro Express cartridge.

A mild cartridge by modern standards, the 6.5×55 has impressive credentials in both the hunting field and in competition. It was developed jointly by Sweden and Norway in 1894 – one of the very first smokeless, small-bore rounds for military rifles. When Sweden boosted 6.5×55 performance in Mausers, Norway stayed with original loads in the less robust Krag. The 6.5×55 defended Scandinavia for most of a century thereafter. In 1990 the National Rifle Association of Denmark, Norway and Sweden renamed this cartridge the 6.5×55 SKAN and standardized its specifications. Still hugely popular among moose hunters there, it has also excelled in 300-meter free-rifle competition.
The long tenure of this cartridge spanned the post-war wildcatting era. Unfortunately for shooters keen to make something new of the 6.5×55 hull, its head diameter is .01 greater than that of the 7×57 (and the .270 and .30-06). The rim is thicker too. At 2.16 inches, cases mike .15 longer than the .308’s and .08 shorter than those of the 7×57 – though as originally loaded, its overall length (3.15 inches) exceeds that of the 7×57. In fact, it falls just 0.1 inch shy of the finished length of the 7mm Remington Magnum! In my view, the 6.5×55 merits at least a mid-length action, such as on Melvin Forbes’s New Ultra Light rifles. Shorter (typical .308-length) actions require deep bullet seating that throttles performance.
You’ll look hard to find a better deer cartridge than the 6.5×55. Francis Sell, woodsman and rifle enthusiast whose book on blacktail deer hunting has no peer, favored the 6.5×55. Hunters coming of age in a magnum culture might question the round’s bona fides on animals as stout as elk and moose. But at modest ranges, with bullets like Norma’s factory-loaded 156-grain Oryx, it’s a sure killer. Modest recoil makes rifles pleasant to fire (read: accurate in hand!) and fast on follow-ups. In Africa the 6.5×55 – and similar 6.5×54 Mannlicher-Schoenauer – felled much bigger game than moose long before anyone necked down the .375 H&H! While its compact case won’t let the Swede match the likes of the .270 ballistically, it is a fine all-around choice for big game in the Lower 48.

Forum member Jerry S. posted this story yesterday in our Shooters’ Forum. It shows that, with the right bullet and good shot placement, the diminutive 6BR is more than enough cartridge for deer.
I decided to try something different this year. Instead of dragging out my trusty .44 Smith or the 6.5×55 Remington 700, I took my 6mmBR Norma Prairie Dog rifle deer hunting. We got a lot of wet sloppy snow the week before the opener and had a freezing drizzle on the first morning. I decided to hunt close to the house since my old bones couldn’t handle the trip to my normal hunting stand.
I set the 6mmBR P-dog rifle up on my shooting bench and began the long, cold wait. The deer trail I was watching is about 180 – 230 yards from where I was sitting.
Buck Lined up in Cross-hairs
At about 2:30 this afternoon, I was watching some does feeding along the trail and looked away for a minute then looked back and saw a third deer moving up behind them. A quick check in the spotting scope showed horns and I got behind the rifle. There is no safety on my P-dog gun so it wasn’t loaded and I quickly chambered a round. The does stepped into the woods and the buck stopped for a minute and looked right at me. I centered the cross hairs on his chest and touched the trigger. I could hear the impact as he leaped straight in the air and hit the ground running into the woods.
I figured it was a good hit, so I poured a cup of coffee and relaxed for a bit to let him tire out and drop. After my coffee, I picked up my 6.5×55 and went out to where he was shot. I was 190 yards from my bench and there was no blood. He was headed toward a swamp south of me so I figured I’d cut him off and see if I could cut his trail farther into the bush. I hadn’t gone ten yards when I came across a good blood trail.
I followed it for a few more yards and found him crumpled up. He had only gone 25 yards from where he was shot. While I was looking at him and taking photos, two more deer showed up. You can see one standing on the other side of my rifle.
My buddy brought his 4-wheeler over and helped me drag it to the house where we skinned it out. The bullet had taken the top off the heart and he was totally bled out. All in all, it was a successful hunt, and the 6mmBR did its job.

Should you sight-in your rifle and practice shooting before you head off into the woods on your deer-hunting trip? Yes, indeed. In the video below we don’t know whether the unlucky hunter’s scope wasn’t adjusted correctly, or maybe he was just a miserable marksman. Many of you may have seen this video before, but it’s still pretty amazing. NOTE: If you are at work, you may want to turn down your volume before launching the video.
