30-378 weatherby handloading questions.

Hi everyone,
Has anyone loaded the new barnes TTSX in 180 gr. with retumbo powder. I have the stock accumark 30-378. I get great accuracy with the 180 gr. sierra pro hunters, but I didn't like what they did at close range last year on a moose.
I want a bullet that will stay together better. I like the sierra bullets but I think the 30-378 might be a bit fast for it. They work great in my 300 win.
I am loading the sierra 180's with 107.5 grains of Retumbo with fed 215m primers. When I look at the barnes loading data I see the max load for the 180's is 105. grains. Is there a reason for that that? Do the Barnes bullets create more pressures?
I bought some 180 gr TTSX and was wondering where to start. Any info or recipes on any bullets or powders would be greatly appreciated.
Thanks ,
Malibual0.

The mono metal bullet will create higher pressure. Start lower than you would with conventional bullets.

Malibual0, how are you trimming your .30-.378 cases? I am having one heck of a time finding products that will trim this particular case. Thanks.

Re: 30-378 weatherby handloading questions.

I have used Retumbo and the TSX 180's and also the 168's in my accumark 30-378. The accuracy was good but Retumbo seems to go over thi line quick. I have had very sticky bolt lift occure in just 1/2 grain step. I would start low and work up.

And for what it is worth, my rifle loves the 210 Bergers over H-1000. I have taken a lot of game with great results with the VLD's.

Re: 30-378 weatherby handloading questions.

I use the Lee case trimmer to trim my brass. I had to phone Lee and tell them what I wanted and they made it for me. It works awsome. I think it was only 15 bucks for them to make it for me.
I also found the same with the retumbo powder, just a little to much( about half a grain ) and I get the hard bolt lift as well.
I think I will start with about 105 grains of retumbo and work up from there.
Thanks everyone,
Malibual0.

Thanks Malibualo0. What trim length did you give them? My Nosler reloading manual says 2.908, while Lee told me 2.903. I know, that is a very small diference, but I really don't want to trim too much (or too little) off each case. Also, how many reloads are you getting per case?

I am just going to use a standard batch of reloder 22 and 200 grain Nosler partition bullets. Using 85.5 grains of reloder 22 will only put me around 136 FPS slower than some other loads but will save from 10 to 26.5 grains per case per other powders!!....and if 2,966 FPS doesn't get it done, I will go to my .300 ultra or .300 win mag.

Thanks again, Malibual0!!

Re: 30-378 weatherby handloading questions.

I gave them a trim length of 2.903" . Its been working great for me at that length.
I am getting 5 reloads per case. How about you?
