38-55 Coated Missouri Bullets

Post by Old Syko » Fri Jun 14, 2019 6:51 pm

Anyone used the Hi-Tek 245 grain RNFP in their new side gate yet? I have a good supply of 2.125 Starline brass and plenty of once fired 2.080 from HSM ammo. Bullets won't be here until later next week so I'm curious as to what I'm going to deal with. Have the 36551 RCBS Cowboy dies and plenty of powder so my only concern is getting them to cycle the way I want. I know these guns are new but thought someone might have gotten started before I did.

BigAl52 might be able to comment, as he reloads, he's a fan of MBC and he has the new 38-55 as well. I've used the HyTek from MBC in my 45 Colt with great success. Keep us posted on how it goes!

OlD Syko better slug the bore. Mine is 376 in the groove. One thing about 38-55 they can be all over the place with bore diameter. Just depends on the gun maker.

Mine measures .3765 so the 2 1/2 thousandths over on bullet sizing should be perfect for proper obturation . My concern is with the crimp groove placement. Will it allow for proper OAL with the long or short brass. I'm hoping to use the long proper length brass.

BTW I think the variation with bore size is only going to pertain to old guns. In the past I've heard of variables from .374 to .384. No way Henry is going to put out such variables in quality.
