Hello everyone,i have been wondering if i'm the only .260 shooter who is interested in the Hornady Superformance powder for this cartridge. I know Hornady does not list it for the .260 but they do list it for the CM, a ballistic twin, or nearly the ballistic twin. I'm curious to find out if some of you have actually tried it and what was the outcome. No one has posted anywhere that they have but i believe it has been tried by someone. I've asked this question on a forum in the USA and did not get an answer. All i received was some lectures on different powders working better,try this,try that, why do you want to use something that has no data listed? So im' asking here because you fellows seem to be a lot more helpful than the USA shooters. Again i want to say, if someone has actually used it in the .260, please respond. I really think this powder would give outstanding velocity with a 129 gr. Hornady SST. as this is what i'm thinking i want to try. I'm shootin a Savage F-Class 30" Barrel from Bartlein with a 1-8 1/2" twist. Thanks in advance. .......SEMPER FI!
