[QUOTE="budlight, post: 1195664, member: 2939"] Really? I own two 243 wins, 9 1/8th twist. One is 22 inch and the other 26. The 26 chronos way over 100 fps faster. So I rarely even shoot the 22 inch and i have considered rebarreling to 27 or 28 inches to make it useful I tested over 10 powders with 100 gr spbt. the powders that came out on top were Superformance, R-25, and now the new R-26. Are those slow enough for you? For Varminting I use 80 gr spbt smoking out the barrel at over 3500 fps and 87 gr V-max in front of H100V. the 87 are at 3400 fps I've never even attempted less than 80 gr .243 because of the lower BC [/QUOTE]
