44-77 brass

[J.B.]

Thanks Kurt. All good information. As both Don and I ..and several others found, the run of JBA brass that I purchased from early last year ( I think thats when it was ? ) has been working fine. Its rims were running the .0715 - .0725" and were working fine in my rifle. The necks averaged .010" and this was working also ( ie. grease groove ..ie. .446/.447 diameter bullets ). While the chamber rim cut is .078".. I've found .076 in the case rim to be ideal. It can up a little but anything above .077 means some camming by the breech block. Not much...but its there. The 'generic' sizes quoted on the Captech site aren't much help as there is no SAAMi standard I believe but they are obligated to put some measurements down as a reference. So Track of the Wolf hey...I gather they are fitting very nicely then ? What neck thickness have they been running by the way ?
This is an observation and heads up and by no means any criticism of BACo. Dave and the gang have kept a lot of us going when others in the industry couldn't have cared less and this may well be an effort to make a good product even better. The best fitting brass I have for this rifle is actually RMC and the new owners there have done nothing but give me assistance and corrected dimensions in the two orders I've received. If anyone wanted to order some of their brass.. they certainly have the Shiloh dimensions now and some shooter feedback to go with it. Their cases are a little thicker though..so you lose some capacity but thats only an issue if you start climbing above about 78 grns or so.. depending on bullet and whether you're gg or pp.

...Just a nervous Aussie not wanting to get caught out
