Case prep. - Kurt - 08-09-2020
I spent the day trimming and prepping the .44-2.6 cases today and my fingers hurt
I been shooting the CPA .44-2.6 and I been noticing the verticals getting higher so I looked at severaL cases and I could see the necks starting to creep up into the 4 degree funnel throat pinching the bullets when they get hit being fired changing the release tension. Also these cases fired with the CPA will not fit the Shiloh .44-2.6. The bases got larger shooting them in the different chamber so I ran them through the base swage die I made to take them down to .500" so they fit the tight chamber bull barrel Shiloh.
I still have to do 200 more but I will keep them separate and not mix them between the two rifles.
I really don't understand why the CPA's chamber is larger they were cut using my reamer. I think they must have polished the chamber after cutting it.

Kurt,
How important do you find the cleanliness of inside necks? Should they be "as new" in appearance, concerning crud build-up? Many folks do a good job of cleaning cases, but the inside neck condition is as the case comes out of the tumbler. I look-over everyone as I use greasers and I wish for a smooth release each time. Are PP folks concerned about this? Any advice is appreciated.

Jim,
The way they come out of the tumbler using the ceramics or set pins is good enough for me.
Stay well Jim.

Jim,
I might add;
I'm more concerned with even neck tension than a little carbon build up inside the case neck that is imbedded in the pores and scratches of the brass.
I want the case neck wall thickness as close as possible in uniformity so when the charge goes off and the bullet starts to expand while still in the case neck it gets a even release. This is more important with the GG than the PP because the GG is seated deeper in the case, but this also effects the PP also but not as much as the deeper seated GG.

Just keep doing what you've been doing Kurt. Your ammo is working fine for me. Just need to get over there and burn some more up for you. ..Mind you.. shooting 44/2.6 might be a stretch in the 44 x 2 1/4

Gavin, just hold it upside down and it will do just fine.
What caliber does your friend shoot that makes the trip over with you ?
Sorry I forgot his name.

I'll try that Kurt...but my varied neck tension may let me down . My mate Gary shoots a 45/70 in the U.S. and either a 45/70 or 45/90 back home. Lot easier to organise cases and projectiles when he's in the U.S. Shakes his head every time I'm having trouble getting stuff together for the 44/77...but I just tell him its a labour of love.
As for case prep, I rinse once with a mild detergent and nylon bottle brush in the necks and do the same again with Birchwood Casey case cleaner before drying them and running them an hour or so in the walnut media. I'd like to set up with a rotating drum and the ceramic media but the cost to set up is putting me off when I already have a system thats working.
