I have recently acquired an 1894 marlin 357 cs. I posted here about what heavy mold to get for it. I ordered an NOE 360-180 on the recommendation of several here. It's a great mold and I really like the boolit it throws.
Here's my problem. I bought some brand new virgin Hornady brass. I have ordered some starline brass for this rifle but it hasn't arrived yet. In working up this Hornady brass I wanted to trim all of it to the same length. My Hornady reloading manual advises a max case length of 1.290 with a trim to length of 1.280. Got my trimmer out and ready and measured the first piece of Honady brass and low and behold, it measures 1.244. The next one measured 1.2475. The next three measure 1.251, 1.243, and 1.2435.
My question is, with these cases being so much shorter than the trim to length what kind of pressure problems am I going to get into by using these shorter cases? These are shorter by .029 to .037 shorter than the trim to length.
I'm getting great groups of 1/2 to 3/4 groups at 50 yards with iron sights with some used Starline brass I had on hand. I've worked up to 14.5 gr of LiL gun with no pressure signs at all.
I hate to have to start over with this brass to make sure I don't have issues with pressure.
What am I getting into if I use this shorter brass?
