I have a new mini 14 tactical with a 1:9 twist. So far I have been shooting 55gr PMC factory loads just to get the brass for reloading and now I need to order some bullets. My question is, what is your experience with different bullet weights? Has anyone played around with a wide variety of weights?
I have, 55grn is the best for 1:9 twist , as far as accuracy in my Mini. It shoots very near that with anything from 50 to 62 grain. We had a good discussion about this at: https://www.rugertalk.com/forum/f38/rifling-twist-rate-question-963/ hope this helps. Jim
