[QUOTE="elkaholic, post: 1070649, member: 13833"] I totally disagree that Retumbo is too slow in this case! Remember, these are not 140-150 grain bullets. RL33 is Much slower than retumbo and I think you will be surprised when Ryan gets his chrono going. This case holds more than the A.I., especially with the throat it has for these bullets. He can compress about 74 grains of RL 33 behind the 165 Matrix. I can reach 3100+ with a 160 in the same case with a 6.5 bore and that with a 26" barrel. Ryan has considerably more capacity than mine because of the throat length, he is shooting only 5 more grains of bullet with a .013" larger bore and has a 27" barrel to boot. The chrono will be the judge, but I am betting that he will reach at least 3150'........Rich [/QUOTE]
