Mauser 3000, set up for long rang shooting 30" bull barrel, not sure of the twist,looking for good target load for punching paper, or the occasional undesirable?

If you can't find anything the 308 Norma is 4% larger. Lower the starting norma loads by that amount and work up.

I also have a 30-338 set up for long range work. It has a 30" barrel with a 1-10" twist. My favorite load used 77 gr. of H-1000, Fed 210 Match primer, 210 gr. Berger all in a Lapua 338 Win Mag case (can't get them anymore). My velocity was 2940 fps with accuracy hovering around 1/2" for 5 shots at 100 yards with an occasional group in the .4's. I was able to shoot this load once at 600 yards down in Albuquerque. Out of the three 5 shot groups fired, the smallest was 2.132" in ideal conditions - first light with no wind. I have other loads that shoot well in my hunting rifle in 30-338, 26" barrel. Let me know if you want me to pass those along as well. I never got around to trying them in my long range rig as the H-1000 load was found early on and I didn't think anymore experimenting was necessary.

thanks for the info big stick will give it a try, my hunting rig is a 340 and thats dialed in . Right now working on this 30/338. Results to follow
