Curious if anyone has any data for the 375 cheytac running 350grn bullets with the imr 8133. I've heard that it's very similar in burn rates as retumbo. Thoughts and suggestions welcome.
Deano, try starting around 125 grains and go up from there a grain at a time until you see pressure signs. 125 grains of Retumbo is a safe and mild load that performed incredible with the 350 smk. Good luck!
One guide I hunt with in Kansas wont let you use mechanical anything broad heads due to too many lost deer.
I have had good results with Magnus on elk and deer for years. I use phat head fixed blade with crossbow.
Brass was the weak link in load development, sd's, velocity and accuracy goals were reached but brass didn't hold up, first part of 2019 I'll have a small batch of new brass to test, If it holds up then I'll make it available to the public and all load data, reamer prints will be released as well
velocities shown in pics were with H50BMG in a 32.5" Rock Creek 8R 7.5 tw barrel

Todd,
I knew I should have just asked you in the first place. I just didn't want to buy you. I appreciate it sir! I finally got all my parts in and put together.

I bought a jgs reamer in late December, they stocked a .375 cheytac. It's got a .100" fb, .4100 neck diameter. It works perfect with the Peterson brass. I bought a set of whidden dies they stock. I had to make a bushing .403". I can seat the cutting edge 400 Lazer and 377 mtac with the sealing band out of the case. I'd think .080 fb would be fine.
