[QUOTE="JTH, post: 1999529, member: 59647"] Thanks for the video. I found it difficult to be real precise with this, but I’d say I’m right about 1 in 10 for the first 10 inches, and got 2 full revolutions (+/- 1/8”) in 20”, but that’s about all the rifling there is in the 24” barrel, with the chamber and the brake using up the rest of the length. Does that make sense? With this in mind, does 181 still seem like a good choice? I do have a suppressor on the rifle, which seems to help a little in keeping velocity up with the shorter barrel (factory ammo is averaging 2,960 FPS) Are there any rough guidelines in reloading for how much velocity you might be able to pick up for every 10 grains of bullet weight you go down? What I’m getting at, is what could I reasonably expect for velocity from 152 to 166 to 174 to 181? [/QUOTE]
