Hi.
Does anybody have some tips for some loads for 360grs. cast bullets?
I'll be happy for everything, but I'd love some loads for Vithavouri, or Norma powders.

I have no direct experience, but using Quickload it looks like a full case (81 grains) of Norma 204 gets you to 2300 fps at 38,000 PSI. That is a good maximum velocity to try for, until you learn how well your rifle and bullets match. The slower powder also often gives the best performance.

MAX LOADS: 78gr. of Norma 203B (whatever that is?) would get you to 2560 fps in a 24 inch barrel. 84.6 gr VV N550 gets you 2559 fps.

I made a lot of assumptions as to COL 3.375, Barrel 24 inches, and bullet length 1.09 inches to get these results. Absolute max pressure was limited to a safe and sane 55,800 PSI.

Don't know about the taylor, but I use 400 gr Hornadys behind 55 grs of XMP-5744 as a fire-forming plinking load in the 416 Rigby. It's not fast about 1800 fps but blows out those big cases using relatively cheap bullets and is extremely accurate.-Rob

Oh -I misread your post. If you are using the Hoch 350 gr GS bullet, again use 50- 55 grs of XMP5744. Cast the bullet from pure Linotype alloy and install the GS immediately. Don't wait or you will be sorry! Wait a day or so for the bullets to harden fully and use SPG lube. Shoots one hole groups at 100 yrds with very mild recoil.
