I kind of think that the lead rings plastered to the case mouth is an indication that the case might be a tad to long and the case is stretching into the throat before the bullet has released the case.
I've also found that running bullets with to thick of paper , and bullets to small in diameter, both can leave you paper rings even in paper patch chambers..

Yessir. That is truly the key to success in these rifles. More so than most of the reloading experiments I've done. I use the acronym from Jim Owens books. BRASS, breathe, relax, aim, slack, squeeze. The one that helps me most is the relax part believe it o not. When I'm having my best days it's always when I'm most relaxed, and the shots just keep on hitting the center all by themselves :-)

I've never seen an actual paper ring Don, but it might be like Kurt has said in the past, that they are being pushed out the bore when wiping. When I got into the paper patching I pretty much went straight with the advice of Kenny and Dan on the big bullets, thin paper thing.

I learned one thing the other day. I have been running my patches about 0.025" shorter than the shank. I tried Brent's idea of wiping with pure water. When I go home and cleaned the bore, the patches came out with a grey wash of lead. No pieces, just color. I guess patching a tad short might be bad. I never had th lead wash before, but probably because I was previously using a little Ballistol in my wiping fluid. I think I'm going to patch the full shank from now on :-)

Chris patching up to the ogive, will likely cause you to have to use 2-3 minutes more elevation.

That makes sense Don. I remember Kurt saying that the bullet will generally bump up as far as you patch it, so that would probably reduce the BC a bit.

As a side note, when I replaced the tall C. Sharps front sight on my highwall with a Distant Thunder, my settings are now 9 minutes lower :-). I never thought that the CSA sights were quite that tall, but then I never measured them...

Chris.

Chris those tall CSA sights aren't good for much beyond midrange IMHO. They are simply to tall and with the additional minutes needed on the staff, reduce the chance of a good cheek weld when the distances get long.
I do like that Distant thunder sight. I'm also a fan of the Baldwin sights.

That Danielson prolate is a very good bullet if you can get it duplicated right. The bullet in the center is Brent's .45 prolate. The left is my .44 elliptical and the right is my .44 prolate. All three bullets shoot very good.
The reason Brent can patch his bullets just short of the ogive is the way he designed the bullet with the small step down from the shank to the ogive. This helps keeping the ogive from setting back from bare lead making contact with the land tops or groove bottom if the alloy is to soft.
The 4 bullets below I ran some alloy hardness tests using the .45-70 and the .45-90 to see how soft I can go to keep the profile of the nose and not change the BC of the bullet's design. The bullet shot from the .45-90 (right bullet) was to soft. The center .45-70 bullet had the same alloy temper as the .45-90 on the right. The .45-70 is just right with the powder charge used in it to hold the alloy from having the ogive set back unlike the one in the .45-90. If you look close that alloy let the nose get set back enough to make contact with the top of the lands and this is what happen to you to get gray on your patch.
The bullet shot from the .45-70 on the far left is almost to hard and did not get full engraving.

That's what I figured was going on. I was using the Buffalo Arms 446535 Money bullet in 16:1 alloy. The bullets were shot over 89gr of OE 1.5 with Kenny's wad stack with the felt in it. Velocity is about 1370fps.

The shank length is .745" if I'm remembering correctly. I've been patching them to .730". I never noticed The lead wash until I wiped with pure water. I'm sure that bare lead has always been contacting the bore a bit, but I guess the bit of Ballistol in my wiping fluid has been enough to prevent the leading.

I'm going to order a copy of Brent's bullet when I get back from Phoenix. I'm not sure if I'll order from BACO or Steve Brooks. I think Steve might have made Brent' first mold.

Chris.

Chris,

Do you know which 1 of the Buffalo Arms bullets is the prolate bullet? I went through the online catalog, and can't seem to find it listed as such. Thanks for any help you can provide.
