6.5 BR AI ???

steve123

Yeah, I know this is in the 6mm BR section but I stand the best chance getting advice here I think. After all it is a small cartridge case.

I shoot 6.5 Saum, 30-375R for big rifles, 6x47l is the go-to for steel and comps(high performer but poor barrel life/1500 or so), but I just want another nifty cartridge that gets really good barrel life, doesn't use much powder, has low recoil, and gets decent ballistics in the wind.

I'm mostly a steel shooter and that's what I will use this for. With my 6x47l I stop shooting early and shoot the least I can because I want to preserve the barrel. It would be nice to save the 6x47 barrel for comps. Plus where I shoot I start at 400Y and go to almost 1200Y as normal.

In the back of my head I can't stop thinking about something like 6.5 BR AI. A handy 26" medium weight barrel. 123SMK or 130 hybrid at 2600 - 2700 fps maybe, 4000-5000 barrel life to 3/4moa.

Am I wrong thinking the 6mmBR gets in the 2500-3000 rounds barrel life and the improved versions less?

I'm not a benchrest shooter but do like to squeeze all the accuracy I can get so that's why I'm considering the 6.5 version.

What are your thoughts on this???
 
I'd messed with a 6.5BRX a few years back that did really well out to about 500yds using 123 gr projectiles , so why not?
 
Seems to me the logical choice for your 6.5BR wildcat would be based off the new Norma Dasher brass necked up and used as-is or run the reamer in another .150 and use up some of that extra long neck space? I'm sure someone has done this already; would be interested to hear the results.

Best of luck!

Sounds like a bolt Grendel is what you need. Outstanding in an AR out to 600. But better in a bolt. Good luck with choice.

I have 6.5G brass on hand, I used it to form 6mmFatRat, but have never done a 6.5G. I've shot AR's in it though. The 123's at 2500 fps were a bit anemic in the wind compared to my FatRat. Great barrel life though from what I've read.

6.5G AI??? what like 2600 fps in a long barrel, but I'd need the bolt specific to the case head. Just thinking out loud...

Great ideas!!!
 
You might search for info on the 6.5 TKS --- I think it's similar to what you're talking about. The designer was named Dan Theodore, and he made it for silhouette.

I actually have a headspace gauge for it. IIRC it has 40-degree shoulder, maybe a bit shorter than a Dasher.

BTW, Hodgdon has reloading data for the 6.5 BR --- that could give you an idea of what to expect.

I run a straight 6.5br with 25” barrel. I run the 108 scenar around 2940 with H4895. The 140 vlds are around 2560 with varget. I’ve used TAC powder with the 140 vlds and had them up to 2720. Hard on brass though.

108’s shoot to good to mess with any other bullet.

That sounds like a fun little round!
 
I am currently waiting on my reamer to ship it is a 6.5BRA that I named 6.5Cherry. according to JGS it will ship in about a week or so. The mocked up round I sent them to make my reamer and go gauge was made to shoot the 108 scenars. I'm building a 600yd benchrest gun. Hopefully it will do well at a 1000 as well. Time will tell, good luck with your build if you decide to go this route.
 
Ha, following up here, afterwards I changed my mind and was going to go with a 22BR, then a 22PPC, then got lazy and went 6mmBR. What swayed me was using a prefit barrel on the cheap since I can buy two for the price of a premium barrel on top of GS fee's.

There's that new 6mmGT and those 25 cal Blackjacks with a .67BC which I'm currently thinking of wildcatting....
