It will do a good job as long as you stay within its range limitations. Me and or my kids have killed several whitetail and even two elk with the 260 rem in a 14" specialty pistol (should be close to what you can do in a rifle length performance wise).
Both elk were under 100 yards (120 NBT's) and were lung shots-both bullets exited.
Right placement+right bullet= dead animal (within its range capabilities of course)
I have a 6mm-225 Winchester 14 inch barrel for my T/C Contender that is about the same as the 6 BR. I use the Sierra 80 gr. SSP bullet at 2650 fps and it did a real number on the one buck deer I shot with it at 100 yards. It went through both shoulders and dropped the deer.
Oops.
6.5BR,
Your user name threw me off-I was thinking 6.5 caliber-Sorry.
My son and I have used the 6mm-6.5x47 Lapua in a specialty handgun and have killed 2 buck antelope, 1 buck muley, and one doe antelope-All one shot kills. used Bergers 105 VLD
Hi Ernie, yes, built a 7BR rifle in the past, last minute, ready made dies/brass...saved a few $$$, and had many 6BRs and one again in the works, and SOME day will do a 6.5 version....but now the 47 and Grendel hit the scene......well you know!
Anyway, how did the Bergers do? Fine I take it.
I'd guess you are getting rifle 6BR speeds in that handgun at least?
I have an rear grip XP, that has been having a new stock being prepared for it, but this is a MOA Maximum (Falling block action/interchangeable barrels).
Scope is a Leupold VX-3 LR/T 8.5-25
The first and only time to date I have shot it beyond 200 yards, was at 500 on steel (3-shots 1.25 inches) no sighters off of a bi-pod.
Here is the post I made it about it and it has pics as well: http://www.longrangehunting.com/forums/f29/mcgowan-barrel-moa-maximum-sp-bergers-great-combo-34094/
I am running it real hard right now and plan to back it off some next time around.
Nice, BIG antelope you killed there! Was that a cow elk, different bbl?
Friend long ago, had a 22" carbine MOA, 6.5BR, shot one hole groups, let him sell it for a song....seemed a pain to load/shoot w/safety design, etc...but regret not buying it ever since, trigger great too. Thanks for sharing and good hunting! You're set!
