Head size stated on tins is a nonsense. Doesn't matter if it says 51,52,53 they'll in the majority be under that and under 4.49. Which I why I ended up testing sizing to 4.48 because it was the only size that marked all the heads all the way around the edge.
Some rifles liked it. Some didn't.
As per others, weight and size and even chrono strings don't seem to reveal the best grouping batch. The only way of finding them is to buy a few and spend some time on paper down range testing.
I've never got a bad batch to perform as well as a good one even with sizing weighing and other playing with pellets.
