Re: Matching Ammo - newbie question
If I really liked the way it shot, I'd chrono 10 rounds and write down the velocities and the temperature etc.
I'd Measure the OAL length, as well as the length from the base to the shoulder.
I'd take a few of them apart and see how much powder was in them (I'd weigh and also estimate the fill volume).
Then I'd jump on Quickload and try to figure out a few powders that are estimated to give the same velocity with the same load and have around the same load density. I'd verify the loads in some loading books and start there.
Even without doing all the above, it is likely you will be able to find a load that shoots just as good (if not better) by reloading.
If you get a load using the same bullet at the same velocity, any drops you have with the factory loaded stuff should be very close.
If some is good and more is better, then too much is just right.
My mind is a raging torrent, flooded with rivulets of thought, cascading into a waterfall of creative alternatives
