Nobody has answered this question ,I have 8 lbs of 8000 and am going to shoot later this morning on my 30 06 and have used it on my 243 with a heavy 105 bullet out a 26" bullet with good accuracy! Talking 1/2 accuracy but believe next tweet I can get it down to 1/4" or less ! Not much load data on this powder frustrates me so I'm going with heavy bullet 190 gr and 8000 vectan 4831 sc worked good on my 1948 harry pope press so as it's the sameburn speed as h4831 I use these figures for a starting load out the 190 sierra boron nitride bulletsDo have 1 lb of sealed TU8000. Hoping it works is a 30-338 project I'm working on.
