Ok second attempt, I pushed the OAL out to 1.15 with 3.6gr of bullseye, I put two full mags through my byf with no problem, but I'm not shooting that any more now that I have a shooter.
I put 50 rounds though my Erfurt shooter and had no problems with feeding but I did have some problems with the breach block not going fully in to battery. When I would push the toggle closed I wouldn't be able to open it, I think the bullet is sticking to far into the bore. I'm going to back the OAL to 1.14 and see how that works.
Also my P.38 didn't fulling eject some casings so I'm going to up the change to 3.7gr of bullseye. Thanks for the pointers Sieger, I will get this work out soon.
