I was extremely skeptical the ULA 50cal with a 1-32 could shoot so well. I guess when it can get over 2400fps with 225g-250gr bullets, the FPS has a lot to do with it. It does quite well with the Parker 275gr at roughly 2300fps-2400fps also but accuracy drops off with a 300gr bullet. Im not sure if its the twist or the extra recoil in a ultra light rifle.

The Savage 50cal with a 1-24 picks up the slack when a 300gr or 325gr is needed. The faster twist helps the longer bullets without the need for more speed. Its still very capable of 2400fps with a many bullets but recoil gets abusive. Accuracy seems to degrade a little also with some lighter/shorter bullets if you push them too fast.

The twists you picked have done well with SMLs and MLs. They have done well in the 45cal with or without sabots. They have done well with smokeless and subs. Knight's target rifle even used a 45cal 1-18 and won many matches at Friendship.

Im not sure why Melvin chose to break from the norm with the ULA and use a 1-32 but the results are well documented on the MM smokeless section.
