Hi Fellas! brand new to this forum. wonderful to see so many brothers in Christ! It is vital important that we not only are active in defending the right to bear arms, (which I find sooooo very important!) but also in defending the unborn, traditional marriage the way God ordained it, and GOOD VALUES plain and simple! Lets be sure not to let one of those liberal morons get into the presidents seat. Sorry for all the preaching, My question is for anyone who has reloaded the h&r .243 model sb2 "ultra". It has a 24" bull bbl. i've tried all kinds of combinations with varget and h4895, 3 different kinds of primers, including match primers, and hornaday 100 gr. and speer 70 gr. bullets. by best group at 100 yds. was 2X4". I remember reading something about an o ring? /something to do with the bedding? I don't understand how this effect the accuracy when the scope mount is attached to the barrel? Also heard about wearing down the rifling with rough bullets, cant understand that one either. I thought that with a high velocity gun, you want to keep the rifling as long as possible. ANY load info or related info about the stuff I mentioned would be greatly appreciated!
