I have the same problem in 9mm with a big 147 gr bullet.

With a short OAL that works in your weapon..................
you need to try Bullseye , w231. cfep or be86 for a load that will maybe work
in your weapon.

Since a long OAL length is out, you can forget about Alliant flake powders
and look at the fine grained powder for your work ups.

Good luck.
