I am getting 5 reloads per case. How about you?

Long story short is I haven't reloaded since around 1995. The only remaining piece of my 1st reloading system are my .30-.378 dies. Everything else, gone....and, trust me, i lost alot of dies, a great tumbler, and, of course, my press.....lost it all between moves. But I just bought another RCBS system and will start reloading very soon.


2.903 is what Lee recommended, too. Thanks!

How much retumbo did you end up using? I am trying to figure mine out as well.

I found a good load with 107.5 grains of retumbo with a 180 gr. sierra pro- hunter. 5 shots at a 100 yards in the size of my thumb nail and 2" group at 400 yrds. But last year I shot a moose and there was no exit wounds. The bullet just expolded on impact. It was a close shot 35 yrds. But if it was a grizzly I would something that penetrates more.
So I went to the 180 grain barnes TTSX. With a 108 grains of retumbo. Not as good of group about 1 " groups at 100 yrds, going 3400 ftps. Shot my moose this year and he didn't go far. I am still going to do some more fine tuning early next year. My C.O.A.L is 3.640" Hope this helps.

Thanks for the info, I tried 110 and it shot a 3 shot group all touching, but it must be too hot of a load for my gun. Bolt wont always open. I am trying to get my chrono to work, but not having any luck.

Broz and others were correct, I had too hot of a load. I shot 4 times with a 108 rotumbo load and everytime the case came out just fine.

My chrono set at 13.5' away from end of barrel, on 3 shots averaged 3475fps.

How does this sound? Its a F1 Chrony.

This seems like it is very fast for only a 108 charge.

What fps should I be trying to get, or am I good were I am at. I havent shot for groups yet, except for the 110, which was under a half inch.

I do have a coal is 3.750, I might move that back to 3.765. Will that change anything?

I am happy for the speed, but surprised. I am sure the accuracy is still there if it was at 110.

Thanks
