That is horrible!!

Lapua will vary 1-2%MAX in several hundred cases. not 7% /ubbthreads/images/graemlins/shocked.gif

You NEED to report that lot of cases to RWS ASAP!

and please report back here...

hi jb100r
thanks for your reply
the cases where once fired ,that 2 friends in france collected for me from the shooting ranges and friends so quite not outta the same batch! but still a large amount of variation! as 7x64 in the uk is as rare as hens teeth but the most popular calibre in europe! if you go into a gunshop and ask for 7x64 ammo ,they will reply did you mean 7x57!
regards scirroco
ive shot the 7x64 for 3 years fantastic round,150 swift scirrocos @2970fps out of a sako

Well, in that case, i would batch them as you mentioned and dont mix batches while shooting.

THough, that still seems like a LOT of variation, even from multiple lots. I would still contact RWS.
