I got all of my reloading stuff in today, bullets and dies, to go with the .375 Win brass that came in the other day. I'm using the Oregon Trails Laser Cast .380" 240 gr bullet from Midway that actually checks very close to .380". That's about optimum size for my bore, which is .374" bore with .378" groove.
I loaded a test round at 2.43" OAL with 15.0 gr of 2400 that chambered without a problem. After bore sighting the TruGlo red dot I installed, I function fired that first round. I then loaded another round with just a partial sizing (call it a neck size, if it had a neck) and then I used the FCD to finish it off.
I knew the red dot was just a little low and at about 25 yards, it shot just a little low.
Recoil with the steel butt plate wasn't an issue, since the load is very mild.
I think I'm really going to like this setup and may put a holograph on it later for a little more compact package. It should do everything I was trying to do with a 250 gr bullet in my .357 Mag Handi, plus as much more as I can stand.
I may get time to shoot an actual target tomorrow, so I can get a better idea of what I'm working with and what needs to be done, if anything.
