Just finished with my 10 cases for the 10.75x65R Collath drilling !

Took the first case and rechecked the trimmed length and then primed them all with CCI200 primers . Next I slightly belled the necks of all them in a raised 444 Marlin expander die . Then I measured out a 16.5 grain charge of Unique and poured it in one case . Well actually before that I set the seating die to crimp on the top of the 405 trimmed case . Then after I put the charge in I seated a Castboolits Group Buy 434-207GC bullet and crimped it . That one was a hair above the crimp groove but it went in the gun okay . Took it outside and fired it into a bank and came back in the loading room !

Took the fire formed case and used a RCBS Universal depriming die and knocked the primer out . Cleaned the pocket and reprimed as well as expanded the neck slightly . Recharged the case with Unique and seated another bullet after adjusting the depth a couple red hairs . Tried the loaded round in the case and it was just a hair snug but thats fine since I hadn't sized the case ANY . Took it back outside and fired it in the bank again no problem , case extracted just like it had before .

So I reloaded the same case for the third time and here's the finished product .

Looks like this thing will get run over the Chrony again wednesday just for kicks . I was getting about 1580 FPS with this load in 444 MArlin brass . So I'll just make sure everything is relatively the same and with 10 loaded rounds I should be able to see how well or bad I shoot at 50 yards with open sights !

craig that should be a real meat gun for sure...make sure to tell us the rest of the storey..... charlie

IF it shoots decent at 50 yards this one will be done until we get Damage Control Permits in late july .

And if it does okay I'll just see if I can't scrape around and get some 7x57R brass for the other drilling as well as try my low pressure 16 gauge #1 Buck loads . I doubt that this one will take much effort .

i bet the old gal will do fine at 50 yards and should do the 100 yard with no problem either...i know the stantard load buckshot load for a sixteen is no 1 buck but ive loaded some no 4 buck it really patterned well...shoot the big gun soon and tell us how she done... charlie

Charlie we finally made a deal on the J.P.Sauer that I posted pics of earlier . Took almost a month to get the guy at a price we were willing to pay . Got a partial box of 7x57R ammo in the deal .

What shell holder do I need for 7x57R ? Or rather what RCBS number shell holder should I get ?

craig i can not help you with the number...wish i could...youll love the 7x57r.... charlie

Craig, just looked up RCBS 7x57R Mauser dies and they list the shell holder as a # 26

Thanks !

When I got home today I tried the shell holder for the 416 Rigby that I've been using with the 405 WIN brass and it seems to do alright with the 7x57R brass as well .
I already have 7x57 dies so after a range trip wednesday I'll be set to try some loads .
