6.5mmBR??

[skeetlee]

Why dont you here much about a 6.5mmBR? I really enjoy the varmint for score shooting and i am currently shooting a 30BR for this game. My 30BR makes big old holes and is very accurate. However, at 300 yards i have a little more bullet movement than i really wish there would be. Most of you know, my mind never slows down and i am always thinking. Over the pasty year or so i have been thinking about a 6.5mmBR. I cant find much reading on this chambering, but in my mind a 6.5BR with a 107 sierra would have to do a bit better in the wind than a 116gr 30cal bullet. I know Varmint for score is about x's and the bigger the bullet the better the chance. A 6.5 would be smaller, but not a huge amount. Are there many folks shooting 6.5BR's and if so what do they usually shoot with them. Varmint? score? group? whats the scoop?? Thanks Lee

Lee,

a chap called Greg Matthews who was (still is?) an Australian gun consultant and writer wrote about the 6.5 BR in Australia many years ago in the long defunct British shooting magazine "Guns Review".

This was pre 6mm BR Norma and Lapua brass and involved huge amounts of case forming, but the results were excellent, and the cartridge efficient as you expect from the BRs. It was built as a varmint / 'roo rifle.

The main problem was as always magazine feed which nobody had sorted back then, so I think the rifle (a Remy 700 if I remember right) must have been single shot.

I may still have a copy of this article somewhere.

If you go with faster twist / heavy bullet, not only wind drift will decrease, but 'intrinsic' accuracy may go down as well.

I've been 'working' with the 6.5BR for a while now, but in the slow-twist mode, ala PPC.
My impression so far is that it is difficult to compete against a finely tuned 30BR at 100Y, or even at 200Y. But at 300Y I can see a clear benefit, I can 'hang in there' with them easily, sometimes feeling like I have the edge.
What could be happening I think is that my 83.5 gr bullets have about the same BC as the 118r 30 cal, but I am moving them at 3400 fps, so that little edge in wind deflection becomes more noticeable at 300Y, I predict about 0.2" difference at 300Y (after wind reading), which is significantly more than the difference in caliber diameter.
I have placed some of my work with the 6.5BR here: www.65BR.com , but still need to make some time and update the page of load development, etc.

Let me know if I can be of further help,

The 6,5mmBR and variants of it are fairly popular among silhouette (handgun and rifle) shooters. I have used one for years and love it, but that is a very different game than BR.

I have a 6.5 BR along with 6.5 PPC, 6.5 Grendel and 6.5 PPCX in small case 6.5 collection...
