Question regarding the gas checks, Do you need them below 2000fps?
Thanks,

I don’t think so but I can’t say when you do need them. I’ve been shooting un checked rifle bullets in 45-70, 450BM (bolt gun), 308 and 222 and have yet to see any leading at all. Also have shot a lot of them in pistols too, 38 special, 9mm (glock 17) 44 Magnum (pistol and rifle), 40 S&W, 10mm and 45 auto. Again, zero leading in any of them.
The only loads I’ve fired over 2000 fps were in the 450BM and those bullets were gas checked but just because that’s the bullet that’s been the most accurate. Same bullet for my “plinking” load too.
