To all, I am up to it again, working on a varmint line of wildcats. Just starting out on this so it will be a bit before they are ready, looking for vialble commerical bullet options to make them work as I want them to. Would like any information any of you could offer me as far as velocity results you are getting with the Berger 50 and 55 gr VLD 20 cal bullets and also the Sierra 90 gr SMK in 22 cal. Basically what I want to know is how fast have you guys been able to drive these bullets and in what twist barrels for best accuracy results. Just as a teaser, I have plans for the 17, 20, 22 and 6mm AV. AV stands for Allen Varminter.
