Looking at building a F/TR rifle in 223 mostly looking for a practice rifle and shooting to 600. But thought about shooting to 1k and was looking at a 1-6.5 twist barrel that was available now. Question is would it give a much shorter barrel life than a 1-8 or 1-7. Not really planning on shooting the 90's which require this twist. Also will I see negative impact on shooting bullets in the 70-80 grain range with this fast a twist. I was looking to build on a 1-8 twist but this barrel is available now versus a 6 month plus lead time on a 1-8. Barrel is a from a premium manufacturer. Would appreciate your thoughts.

Do you have a 308? if you do, shoot to 1000 with that. It cost close to the same to reload each the .223 and .308.

i doubt you'll see much diff in barrel life. i bought a 1-7" Hart just like that (it was in stock and available) and would do it again. it's a shooter. granted, 1-8" is where it's at, and i run that twist also, but the 1-7" twist gives up little.

the downside is 1-6.5" may nuke some lightweight varmint bullets at warp speed and faster twists don't do so well with cheap bullets that may not be as concentric as match bullets.

Re: Barrel life of 1 in 6.5 twist 223 barrels vs 1-8

Thanks for the insights, got plenty in the 308,6.5 and 6mm range to play with and got a 223 with a 1-14 inch twist that drives tacks with 52gr SMK's. Really just trying something new. Was told that 1-8 was the way to go with 69-80 grain that I'm looking to shoot with this thing. Had a discussion with someone that was dead set against the 1-6.5 inch twist said it was to quick and premium accuracy went away real quick versus the 1-8 twist. I was wondering if anyone had seen that in a 1-6.5 where it shot very well and at 1-2k saw it the open up another 1/4 to 1/2 inch in grouping. He compared barrel life to the 6.5-284 or worse. I just don't see that myself at least not that bad in a 223. Anybody seen this?
