Christel has been diligently filling cases for me today, and as it is a new year I thought it was time to confirm the OAL in my AI again, it has moved 8 thou with 155 Scenar's over the last 12 months, not sure if that is good or bad for a 7,62x51
Anyone?

Re: Chasing the throat..
Sounds like quite a lot of erosion, but I guess that depends on how many rounds since last measurement, what type of powder and load, and what type of barrel?
Presumably you're using identical tools (same comparator etc)?

Rox, Same comparator, different OAL gauge and case as I use a different thread these days so that may well contribute partly to the variation. Border barrel, 155 Scenar's with 47.5 grains of N540 and it has shot just under 1500 rounds over the last year including some very hard hitting Danish milsurp.
Rob, It has started to give string vertically. climbing my maybe 1 MOA at 1000 yards over the first 3-4 shots, it then settles down and holds reasonably well. I need to get the old book out and have a count of the total number of rounds I have put through it.
