Thank to Texas Tim for this. He's reloading long range 300-1,000 yd benchrest - non trivial!
If I wanted simple I'd buy a box of 20 off the shelf. I want to tune this rifle to shoot 1/4" aggs @ 100 yards. I'm not a plinker.
I'd hoped to express in my original post that this was an accuracy based thread. I welcome suggestions for more accurate measurement techniques. No dremel or dimple slip sleeves making up rounds that have to be measured and translated, using comparators, into die settings.
Taking the bolt apart to determine exact measurements is trivial. It takes less than 15 minutes. I'll do it once or twice a season, and requires a flat washer, a dime (big spender) and a 1/16th punch for the Remington. You can use comparator readings for bullet changes. Bolt disassembly should be done as part of periodic maintenance anyway.
It's the other stuff that's expensive and time consuming. Excellent matched prepped brass; match bullets and primers; exactly measured powder loads; concentric bullet runout; bedding; accurizing,; scopes, rests, bags; membership, gas money etc. And I love every minute.
This reloading procedure produces the most accurate benchrest seating that I can reproduce. I'm not really interested in quicker, easier, cheaper. I want consistent benchrest quality reloads.
As I said your mileage may vary.
(Is removing savage pin ugly?)
ps - i'll sell my Sinclair bullet seating depth tool for $10 plus shipping
