I woke up this morning around 5AM and for the life of me couldn't get back to sleep. So instead of counting sheep I counted up all the reloading stuff I need to buy for the Spring .50 BMG initiative, where Michael Attempt To Get Beyond The ".50 Plinker" status. I've been lucky enough to put a lot of Big 50 rounds downrange from a bunch of different guns, including a few rounds through my own Barrett Model 99 single shot. I have a Hornady .50 BMG reloading set-up, and it works fine as long as it's a few rounds (think "power case trimmer!").
The .50 is irritating to reload because it's not like a "regular" commercial cartridge...specs are all over the place, since the cartridge was designed for the Ma Deuce with its adjustable headspace and blunt trauma style of operation. This is especially an issue with primer pockets...it's hard to screw up repriming a commercial cartridge, unless you put the primer in upside down. Not so with a .50...you can seat 'em too deep, or over-crush them or, in general, screw up.
So I'm looking at a dedicated primer seater like the M2 Precision. At $300. Or the Hornady primer depth gauge, at a liitle less painful $117. I'd like little more precision in seating the bullet as well, so add another $238 for a CH-4D in-line seating die. And let's just flat out deal with this case trimmer nightmare, which means at the top end some sort of power tool like a Gracey or the painfully expensive Giraud, or more sanely a hand-cranked Forster, which I've used before on other cartridges, or a K&M, which comes highly recommended.
One thing I can unequivocally say for the .50 BMG...it makes every other shooting sport cheap by comparison!
