I've recently been given a selection of .243 ammo from a very generous member on here and was just after the best way to test the selection in one outing to the range. I've only got 7-8 or so of some rounds and up to 20 of others so want to know what people think to get the best results.
Ive heard some say I'll need to clean the barrel between brands to have a baseline but then will only 7-8 rounds be enough to get an accurate representation between cleans. Also how many to fire in what time frame to keep the barrel cool and let it cool between test?
My set up is a Tikka T3 lite in a Boyds thumbhole stock with P8 Wildcat.
