TOF, of course I have a manual, and would never jeopardize my rifle OR my body
I am only using recipes from my Lyman 49th Re-loader's Manual.
But here are my results:
I was a little hesitant on the lighter weight 40gn. bullets, due to what my manual said, "barrel twists of 1:9" or more should use lighter weight bullets (36gn - 50gn,) but barrels with twists of 1:9" - 1:12" are MORE ACCURATE with heavier 55gn - 65gn bullets."
But my recipe 20.5gn of IMR-4198 (right out of my Lyman Manual,) paired with the Sierra 40gn bullet, I was shooting -1" groups @ 25 yds!!!!!!!!!
I am QUITE sure that @ 100yrds the tables might have been turned, but @ 25 it was the ticket I've been looking for! VERY accurate in my Mini-14.
One thing's for sure... This whole reloading thing boils down to this: USE YOUR MANUAL, and find out what works best in YOUR rifle! For me: I think I found a GREAT recipe for my 25yd shooting needs!
Thanks again for the input,
