I finally got a couple of loads with the 100 gr TSX to work in my .257 Wthby Vanguard. I tried all the "standard" powders but could not get the accuracy I wanted...or even close to that level. RL-22, IMR-7828, IMR or H-4831, etc. Finally, H-1000 at max levels came together. Work up to this load, of course - but 75.5 gr of H-1000 with Federal GM Match Mag primers in Weatherby brass grouped in between 1/2 and 5/8 inch consistently. Now I have to chrono the load to see what velocity it is giving.
Ramshot Magnum came close to those groups, but not quite and I cannot find a single store that carries it locally.
Now I can go out and shoot the rifle at distance and see how it does.
