has no one tried to sand or mic down the brass to the proper spec? I get that would be time consuming, but maybe worth it and theoretically possible...

Neck turning would be the solution here, but after shooting nothing but tight necked wildcats for the last decade I'm not doing THAT anymore.The Collector wrote:has no one tried to sand or mic down the brass to the proper spec?

There are faster ways to accomplish it, but this should give you the idea behind it. Doing large quantities is quite the PITA. For my time, it's not worth it with the 300 BO to salvage a few cases with overly thick necks.The Collector wrote:What is neck turning, How is it done?highxj wrote:Neck turning would be the solution here, but after shooting nothing but tight necked wildcats for the last decade I'm not doing THAT anymore.The Collector wrote:has no one tried to sand or mic down the brass to the proper spec?

I turn all the necks on Blackout brass using a Forster case trimmer with the neck turning attachment. You can screw the handle off, thread a 5/16 nut back on the shaft and then use a cordless drill to spin the shaft. Doesn't take long at all, is certainly quicker than sorting through piles of brass, and yields a better result.The Collector wrote:What is neck turning, How is it done?highxj wrote:Neck turning would be the solution here, but after shooting nothing but tight necked wildcats for the last decade I'm not doing THAT anymore.The Collector wrote:has no one tried to sand or mic down the brass to the proper spec?

What about just bolting a power drill the bench and chucking in a piece of brass, and spinning it it against a piece of 600 grit sandpaper. Measure, rinse and repeat until the proper thickness is made?Poorboy1015 wrote:I turn all the necks on Blackout brass using a Forster case trimmer with the neck turning attachment.

Yes, you could remove material that way but I doubt it would be precise enough. All that measuring would take a lot of time too.The Collector wrote:What about just bolting a power drill the bench and chucking in a piece of brass, and spinning it it against a piece of 600 grit sandpaper.
