slip-fit bullets

[Old Jim]

I will try a few slip-fit bullets in various loads this spring. My new Boomer mould has tapered bands and bullets can be seated out a'ways. My question is about contact in the barrel ... does the loose bullet need to touch gently in the throat? I am concerned about fouling after a few shots and while using a BT, I don't need to fight loose-fit rounds being forced into the chamber in this old roller.

ALL experts are welcome to weigh-in ,

I always try to get a slip fit load working before I add neck tension. I like to leave the brass alone if I can because it's simpler, but some of my rifles/bullets prefer some tension. I've been loading them with a little compression and with the bullet just touching the rifling.

My new .40-65 sure likes it that way. It's chambered about perfectly for slip fit IMHO. The only trouble I have with slip fit, is that if you don't anneal reasonably often, sometimes a fired case will no longer accept a bullet. Dan Theodore wrote about that some time ago. After 4 or so firings on my Rem brass (and no annealing), maybe 4 or 5 out of 50 cases will no longer take a slip fit bullet. My sloppier chambered C. Sharps highwall only rarely does that.

Got to the range this AM with the 45/90, and its embarrassing to say that all loads were cr*ppy!, 'cept for one F.L. sized load firing a BACO $ bullet and 82.0 Old E. It showed promise, with a 4" group @ 200. So, I returned home, loaded 10 more, with 85.0 of Old E 1.5, then back to the range. Better, 1.75" @ 200 yds. this time, for all 10 shots ..., first 3 in one ragged hole, I'll take it.

For the near future, I won't be testing any more slip-fit loads based on these results. I have some 1.5 Swiss I will try with the same bullet on another day.

Happy Easter to all that visit here,

Happy Easter to you to Jim. Last Sunday we had a Buffalo shoot at Carthage, me and my son went up. 1,2and300 yd. match. Jeremy got 2nd place with my Shiloh 30/40 Krag and I got 1st with my 38/56 CPA I got 2nd with my MVA scoped Hiwall in 40/65. so except for the rain It was a great day. Plus got home today and there was my new BACO mould. .446 money - slick, cast 50,cut paper and roll em up today.

Here's pic of 300 yd. target 535 BACO $ bullet and some Old E ...

I used an online ballistic program for the 300 sight-setting, and as you can see, I almost missed the whole target. I will try some 1.5 Swiss in this same ammo at a later date. Looks like it may be ok.

That looks really OK :-)

Nice, very nice.

Update;

Recently, I acquired a Browning BPCR, 45/70. It did well with the BACO $ 535, as in 2" @ 200 yds. Those cases were fl sized.

Now, eating crow about never trying slip-fit bullets ever again ... I have ventured back there again.

I am trying the Boomer Money bullet, 535 gr. slipped in to lightly engrave the bullet and 74 gr of 1.5 Old E.

The Brooks New Postel @ 530 gr. caught my attention so I have loaded a few of them also, same charge, engraving also.

I'm off to the range. Film @ 11!

Heres a 200 yd. target with the Boomer $ bullet. The 300 yd. target area was being used by another.

Boomer's $ bullets have a longer , tapered nose, unlike the original money bullets. The first driving-band is same dia. as the nose, 0.448, making room for more powder, they say. The Browning rifle used is rather picky about how much engraving, compression, etc. goes into the loads.
