Would you mind (maybe in a separate post to avoid further clutter here) expanding on this?Y’all have chamber issues then.
I have a .243 AI Tikka rechambered by Kampfeld that went from mild pressure, 3130 fps at 52.5 gr H1000 brand new, to heavier pressure signs at same velocity with 4 grains less powder after 150 rounds. I've got a load well under pressure now that I went ahead and loaded 150 of and so far so good. I'll take a little slow and no cleaning over 50-100 fps higher and cleaning required if it works to do it this way, but wanted to get your take.
