D Ccots, I agree with you 100 percent. Hey Steve, see you at St Thomas before long.

so not a PRECISION rifle like a benchrest gun.
not precise enough to tell the difference.
basically the test equipment was not up to the test.
do it again at 600/1000 yards with a benchrest gun.
you can use your weighed primers( I do to)

This,was a custom 708 shiloutte rifle. That was many years ago , not sure if I shot the groups at 200 or 300 yds. I think 200. I have shot hundreds of various matches and have never heard anyone say, I won first because of my matched cases. I have heard shooters who wii throw a case away if they .shoot a shoot wild out of a group in good condiitions or if a case falls off a bench and makes any kind of mark, or even if it leaves no mark. Why, just because I suppose.

Ray, you are correct not the same as a benchrest rifle but not bad. I shot it for 2 years at 500 yd ground hog matches and won quite a few with it. My intent here was not to convert anyone but just to convey my thought on weighing cases and why I do not do it.

how do you get .014 on 30br brass ??

I turn my Lapua 6.5x47 brass to .0125 when required. I only turn necks to overcome excessive variance in neck wall thickness. After 4 or 5 firings/annealings, the necks can vary as much as 3 thousands. I turn these cases down to .0125 to get a variance of .0005.
Same thing with .223 Lapua cases.

Unless you shoot popsicle loads as you fire and size, your necks will grow in thickness. So not only to you need to trim the length as they grow but if you have a tight neck chamber the necks will over time thicken and might need recut to maintain proper wall thickness.
