[QUOTE="mikebob, post: 211964, member: 6041"] I shoot 47gr retumbo 90gr bergers .007 in and lapua brass and not at max. My throat is long though, i couldn't get enough pressure out of retumbo with 80 gr bergers or amax's, velocity was about 150fps slower and getting powder down bbl. I have loaded my lapua brass about 7 times each and still good. You have to make sure you dont bump shoulder back to much or you will loose alot of brass with this round. 47gr with 90gr is a compressed load and 48gr with 80gr amaxes is compressed enough it was putting dent ring on the bullet but still wasnt at max for me. I think if your going to shoot retumbo youll need to shoot 90 grainers which you should be able to do mine is a 1-8 twist. I was going to try 4831 with the 80's but i tried the 90's and they worked so i went that way instead. If i remember right i was getting 3450 with 46gr r22 and 80gr bergers which was a max load in mine with a long throat. With mine i seamed to have best accuracy around 3400 with 80gr. [/QUOTE]
