Was wondering if anyone out there in LRH land has any experience using Hogden Superformance Powder for any of their reloading. I have been working up a load in a custom 6.5CM with the 120 gr GMX bullet. Any input, good or bad??? I have the current Hornady manual and they dont use it for any of the other rifles I shoot. These are the bullets I'd like to shoot if possible. 6.5 CM 120 gr Hornady GMX 280AI 150 gr Nosler LRAB 338-06AI 210gr Barnes TTSX 22-250 36gr Barnes Varmint Grenade What is a powder with a similar burn rate???
