I’m using 54 grains n560 @3060fps with the 135 Berger, Norma brass,1-7twist 25” Benchmark on a M77 action that shoots 1/4 moa. My son took this Sitka blacktail in Kodiak two weeks after we got the gun back from the gunsmith and the Berger’s dis the job.
I just picked up my 7twist 25-06 yesterday from the gun smith and will be testing the 135’s this weekend hoping to get 3100fps. I used a M77 action and a spiral flute #5 Benchmark, HS precision stock. Will be testing N560 and h4831.
I’m starting a 6.5 build now and have never thought about a 6.5 280AI and your data is exactly what I’m looking for. What’s your estimated barrel life compared the 6.5-06?
I’m Ryan from the southern Oregon coast. I love hunting,fishing, shooting and reloading. Looking forwards to all the experience that lurks on this forum.
