I loaded some 230 bergers .743 bc

rem brass 215 match primer 89gr retumbo at 3.9 length

3 shots fired smooth with no pressure signs at all

1. 2971
2. 2983
3. 2977

My goal was 3k fps which looks like it will be easy to get there, I will shoot some paper soon and see how they group. Shot out of a sendero with DE brake ( Thank you Shawn ) awesome job and nxs scope 26" SENDERO tube. Do these velocities look normal to you guys. I was expecting about 2850 fps. Looks like 20.7 moa @ 1K yards 2018 fps and 51.2 moa @ 1760 yards 1442 fps and 64.3 moa @ 2000 yards 1300 fps. At 1k yards still has 2081 ftlbs of energy plenty for elk.

That's very encouraging because I plan on running those out of my 300 Jazz.Thanks for sharing.

My load with the 230's out of a 27" select match HV barrel is 89.5 Retumbo( Fed 215 large magnum match primers) getting 3000 just touching the lands. I am going to be playing with seating depth today trying 5-10-15-20 out and 5-10 in to see how the groups play out. Right now I am under 1/2 but I know the gun can do better and has with the 208 Amax.gun):cool:

I thought the 230s were supposed to not be finicky with seating depth. I hope they shoot good out of my sendero. I usually shoot the 208 amax but i wouldnt try to kill an elk with them.

What dies are you guys using for the 230s? I have a rcbs rock chucker supreme reloading kit and was going to get the rcbs dies to go with it. Will this setup work or do the 230s require a special seating die? Do you full length or just neck size?

Also, how do you work up a load for your 230s? I was planning on finding my max coal and max charge, then seeing how it groups. And then play with seating if I need to for better accuracy. Am I on the right track?

Thanks for any help!
