A Swedish Rolling Block comes back to life

What are you using to trim your brass, don't see any trimmers with 50 cal pilots listed??

Cheers

A bit of a Backsheesh solution, but here's what I did:

- buy the Lee oversized trimmer head, and the case length gauge for the 500 S&W
- mark the 50/70 case to length (1.715")
- carefully trim down to the mark

You could order a custom case length gauge and not have to do the marking, but it's not a must. The 50 I did up will last a very long time with the mild loads I use.

Got to shoot her today. Loaded 28 grains of Hodgdon 4198 with a LEE 515-450-F bullet over top, lubed with 50/50 alox/beeswax. Extremely happy with the results. Even with the crappy sights on it 3" was no problem and the gun was extremely consistent with no fliers at all. Shot some pop cans at 100 yards with ease. Very fun caliber to play with. I was grinning from ear to ear. Got an 8x58r on the way now. Wish I could find a nice full military one in 12.7 x44r at the sporter price range.

Andy...just to add to your procedure for trimming. I pressed a deactivated primer backwards into one of the 50/70 cases to index from for length then ground the pin on the 500 SW trim length gauge to give 1.720" trim before the pin bottoms out. This made it easier to trim to length without having to measure over and over again. I'm planning on cutting the cutter handle down so it will chuck in my 1/2 " drill press to speed things up even more.
 
Andy, interesting that you mentioned the others.
Also Have a Danish rolling block (11.5mm) or .45 cal.

And with a Canadian Armourers funnel, clean up is no problem.
 
Excellent idea - I'm going to steal it. ;)

Andy gotta thank you for that 4198 load. Took mine out today with some soft lead bullets (8-9 bhn). First 3 shots cloverleafed at 100 yards. I should have put her away but went for 5 and opened the group up to my standard 3" grouping. The boys better watch out at our next milshoot. these things are like crack though. I have 2 now with a third in the works and am considering a a full military in 12.7. Shot the 8X58R along side the 12.7x44R and it just could not keep up
 
The amount of flames blasting out of my 308 today as I sighted in Stevens 200 using ammo loaded with H335 averted me from that powder. Must be way too hot burning powder, probably safe to use in short barreled chrome lined semi-autos, but that would be it.
 
I don't want to HJ the thread, but it's a standard Steve 200 with Win LR primers and loads of H335 ranging from 41 to 42.6 gr behind a 150 gr Hornady FMJ seat 0.015 from the lands and slightly crimped (of which I regret and won't do again).

Great pics that show just how high the lands are on the bores of these old girls - makes the bullet look hexagonal.

Is that the Lee 450gr? My gun loves it - I tried the 500 as well, but the 450 shoots better in my gun.

Having some loading issues the guys on cast boolits are helping me to sort out. Cannot chamber a loaded round without putting a small roll crimp on. Seems the chamber is too tight or the brass is too long or boolits are too big or ???

As suggested, I'd shorten a round 0.125", load up a lubed bullet to the same OAL, and see how it chambers. You do not have enough chamber clearance as it is, and I would not reduce the bullet diameter, as it shoots so well as it is, so you must either reduce length, or inside ream the neck of the brass. You could also ream the chamber to 50/70, but there are easier and cheaper solutions.

What neck diameter is your fired brass? You want 2-3 thou minimum over the diameter of the brass sized with bullet seated - anything less and you are looking at neck pinching and high pressure.
