Anyone got a good recipe for reloading the 69 grain matchking? Anyone have any recommendations and/or things to watch for?
+1 on varget. I love that powder it has always been a performer for me. Also +1 on small base dies, this is a must for reloading cartridges for any semi-auto.
I usually back of a bit from the book. Unless you are trying for maximum range, the higher velocity tends to aversely affect accuracy if all other conditions are equal. However, with the length of these bullets you need a fairly quick twist with a decent velocity to get them to stabilize properly.
It is good to pay the insurance early and use small based dies. A semi beats the brass up, and you will be replacing brass after 6-8 times fired or earlier depending on how hot your loading it. SB dies help with getting that round into the chamber. I use a case gauge anyway, and have had no failure to chamber issues. Piece of mind anyway. JPG
Not trying to cause a pissing match, but you should think about the saftey of you throwing out your wisdom on the internet. What if this guy was asking about an M1A and he used your advice on using a non small base die, and had a round go off with the bolt slightly out of battery? Which has happened more times than it should, by the way.
Say he blew his gun up, at the minimum. I bet you wouldn't even say your sorry, would you.
