So, with the supposed shortcomings, how DID IT SHOOT? I only ask this as I've seen some pretty good components shoot like crap and some stuff that shouldn't do worth a hoot turn in 1/2 moa consistently... I've had 7mm stw fireforming loads with 375 h@h brass haphazardly trimmed with tossed charges toss ten in 3/4 inch. I've seen 30-06 with 3 different primers and 3 different brands of casing but a bullet the rifle liked and a decent powder dump 1/2 moa.. I've also had groups with turned/ uniformed brass that would make a shotgun cringe. The brass is a vessel; as long as it fits with a few thou. wiggle room to center and isn't a total joke concentricity wise you will probably not notice the difference in most rifles.Here's the measured Weight Data Grains:
Lapua Dry Filled with H2O
336.5 451.4 114.9
329.5 446.7 117.2
330.2 446.35 116.15
Avg. Case vol. water weight Lapua 116.1
Hornady
319.3 426.8 107.5
318.8 426.4 107.6
Avg. Case Vol. Water weight Hornady 107.5
Do your own comparisons. This was on once fired brass. Clearly the Hornady Brass weighs less Dry and has less volume of H2O
when filled. Could be its just shorter in the neck or case, or maybe it doesn't have the same alloy, weighs less and is less volume.
Yep, try this on your own too.
More people on this site have trouble staying in nodes with fickle bullets than really have any issues with modern brass. I hear people chasing bad loads that they spent 1/2 of their barrel life developing and wondering why their trickled charges and perfect brass couldn't fix a poor barrel/ bullet relationship. I've dumped deer at 1/2 mile with 140 grain 7mm flat based pills in a factory sporter with tossed charges in rp brass. The trick was the rifle would consistently shoot 1/4 to 1/2 moa.. Offhand at distance was rather easy knowing exactly where the bullet was going. Too dang bad I shot that pipe out.
