It's 7.5Your barrel twist needs to be at least an 8 twist.
Just wondering about some 22x55 loads.
Just wondering about some 22x55 loads. I'll be loading Berger 80gr VLD's. I got about 1000 pieces of prepped brass so I need to work up a good load.
I had one of these similar to what you're talking about, mine was called the .224 Vais. Shortly after putting everything together I found a chart that gave expected barrel life for X number of grains of powder for a given bore size. The chart gave me an expected barrel life of 800-850 rounds because of funneling that much burning powder down a .22 caliber bore (blowtorch effect). I found a guy that wanted it worse than I did, so I traded him for pictures of dead Presidents and it followed him home.
