Thinking about this for the heavies, 80''s. and 90's. Pro''s & cons
I have an 8 twist that shoots everything up to 82s just fine.
What velocity are you getting with the 82's?
I have one however, I haven't shot it yet.
Let me know what you think after you shoot it
I'm wondering if it would work on th 90's. It would be an alternative to a 224 Valkrie.
Will do, I have brass ready to shoot in th 22BR and just need to finish load testing on a .222Rem that has been in the safe way too long.
Thanks so much
Pro; Can stabilize heavier bullets with higher BC's, less drop, less affected by the wind.
Con; For any given bullet you cannot achieve as high a velocity as you can with a slower twist barrel, more drop and more wind effect.
Yes, I have had a 7" twist 22BR and a BRX (and still have a 9" twist 22BR).
The 7" twist with 90gn Sierras and Bergers was great to shoot and very accurate. My best shoot was 2 targets at 600Y which scored the equivalent of 200/19X on your F class targets. The ballistics with the 90s was slightly better than a 6BR, with lighter recoil. Down side was lower barrel life compared to 6BR, and when I utilized the extra velocity of the BRX, some Sierras started coming apart once the barrel started to get a rough throat.
I’ve had good luck with 90’s and 1-7 twists on my 22br , just rebarreled it! I have to make sure that the throat is long enough for base to be in the case neck or it doesn’t work well.
