thanks for the responses, i will also be doing something similar as I know which bullets are which now...
this relates to SMK's, not Bergers, but worth sharing,
I traded some first gen Berger 338's for some SMK's the person I traded with packaged the SMK's worse than a 5 year old would have, threw them loose into a flat rate small USPS box with a peice of newspaper crumpled up.... no additional tape, or anything even holding the bullets. I lost a bunch of bullets on the way to me, 67 i beleive, person said they would send me more, never did, i figured as much, anyway thats another story,
but because of this, the tips were pretty messed up, meplats were damaged, but all still had the cavity
i tested some at only 50 yards to compare to SMK's I had previously that were not damaged at all.
at 50 yards with wet newspaper stacked together pretty tight:
the normal non-damaged SMK's entered at 338 diameter for 1-2" then for the next 2" or so started to open up, and from 5-16" through the newspaper, there was a 6-7" hole, that tapered back down, and I found the copper stripped back with barely any lead at around 24" deep in the newspaper, I did not test many, but they all did the same thing.
the ones with damaged tip, went in 338 diameter for an inch, then for 2-3" more there was around an inch hole, then it went up to 2" or so for another 8-10" and exited 25" of wet newspaper, not a very big exit hole though.
so again, I will test the Bergers at 50 yards, and it should show a bit, I know longer range would be better, but this will serve 2 purposes for me, show whether the ones with the deep cavity open better than without, also, if I have to shoot something close, it will show me what happens.
I know that it really should not matter if close and on softer tissue, but I have done the same test with a 300 wsm
and 168 A-max's, and it was pretty bad...
bullets entered the cardboard box housing the wet newspaper, then fragmented and pretty much went upward, almost no damage past an inch or so in, multiple shots did the same thing, so that worried me for hunting where I may need to shoot something closer.
I will let you know how this goes and post pictures and such.
also, anything I should try to do special with these tests or any advice?
