I had a barrel made for my 300 winny in a 1:7 twist rate with 30” length. I had the barrel built for 230gr Hornady A-tips. My shooting buddy talked me into it. I have not found much in the web in regards to others using this twist rate except for 1:8 twist is more than enough to maintain stability. I have access to a 2000yard range and I have been successful with consistency at 1300 yards with my current 1:10 twist barrel. At the mile im starting to struggle hitting the plate and at 2000 I’m wasting bullets. Has anyone tried using the 1:7 with this or similar bullet with any success. My thoughts are with the advancement of these high velocity bullets nowadays the jacket should hold. Any constructive thoughts?
