So for giggle shits I did some brass measuring.
-6.55x56 lapua(rim.478/thick.055)
-30.06 hornady(rim.468/thick.050)
-308win brass(rim.471/thick.050)
-hornady 308( rim.470/thick.050)
-lapua308(rim.471/thick.050)
So I guess your right the 6.5x55 lapua brass rim is thicker by .005 than 308 and 30.06 brass I had to measure. Should I call the smith and send him a sako extractor and have him open bolt face or call him and send him some lapua brass.
My experience has taught me simply having a Sako or M-16 extractor, or simply having a PTG bolt will usually avoid most/any problems with Euro Swede brass. But if you're working with a std Rem bolt and std Rem extractor - it's best to double check.
I would send him a couple cases and if it doesn't work without a hitch, then have him order or send him a Sako.
