Whistling to classical music, yes, the thought alone is annoying.   

Well, got an update. Had a busy day at the range. Started off breech seating with Unique. Tried 2 different bullets, a Lyman round nose that cast at 413 and a buffalo arms money chicken bullet that cast at 435. Got ok results, but definitely nothing to write home about. I did not have high hopes for the Lyman bullet because I had to size it down .005. Next off tried fixed ammo with the money bullet and it got better, but still not great, then got to the Lyman bullet and found magic. The picture below is 5 shots at 200yds and just under 1100fps.

Moved on to duplex loads next. Used 7gr 4227 and about 80gr Swiss 1.5 with a .060 was and a 3/16 felt was. Holy crap that had recoil! Sill was ok, but not great, about a 4" group.

Moved to fixed ammo with 83gr Swiss 1.5 with a 535 buffalo arms postel (my silhouette load) and got much better results. Found out this rifle does not like breech seating. Had some windage issues, but I think that was caused by the fact the benches were not long enough to rest the barrel where I do off sticks. The vertical spread was great though.

Definitely learned a lot today, and with 120ish shots of 45-70, I'm feeling it! The fixed load with unique was the clear winner

Here is my breech seater. It is set where the base of the bullet is JUST barely engraved to the base. The bore slugged to .458, and the buffalo arms bullet I used was a reduced band .459. The barrel is a factory badger, so it's not set up for breech seating, which I think is part of the issue. Another part of the issue may be that unique doesn't like being so loose in the big case, so another powder may work better. 

I pulled out my calipers and the fixed ammo group put 4 shots into .74" (edge to edge measurement) at 200yds, I pulled the 5th, and had an ES of 8. I think it's going to be hard to beat that

Over the past 20 or so years I have often shot a 45-70 in local Feuerstutzen matches. By strict rules (Bavarian Feuerstutzen) it is not allowed because rifles must be in 8,15x46 and must be original or replicas of Teutonic rifles, original or replicas of American guns are VERBOTEN!

Anyway, I never expected to win and was in the game for fun. I shot 500gr lead over BP with a 5744 kicker. As said previously, the roar of a full charge and lots of smoke really aided in my placement on the score sheet

Three years ago I got a Shiloh Business rifle to continue this and put MVA sights and a level on it but no shoots have come up. No I have just acquired a Browning 1885 Trad hunter in 30-30 and equipped it with MVA's and got a palm rest for it. Now researching the rules I have discovered I still cannot legitimately compete in Feuerstutzen, wrong caliber wrong action. Oh, BTW, palm rests are not allowed either

Looking at our Unique load, where was your dacron wad and your .030 Walter's wad placement in the load? I can sympathize with the pain of recoil after shooting a lever gun match with the afore mentioned load that I posted and I'm looking for a reduced load and that looks like a great one. Tighter group too!

So I took pictures of the whole process. There was a quote I heard a while back "I do 10 steps, 4 of them are probably pointless, but I'm not sure which 4." That may apply here.

First, I full length resize, expand the case mouth, then clean the brass. I put a strip of a #2 coffee filter on my primer seater, and use the primer to punch a wad when I seat it, then I dump 12gr of unique on top. I cut pillow batting into roughly 3/4" squares and stuff it in the case, I punch it down just a hair to make it easier to put the next wads in. I put a .030 fiber wad on top of the pillow, my thought is the pillow was is a bit "stringy" and the fiber wad seals all that from getting in the bullet lube. Then a newspaper drop wad to keep the fiber wad from sticking to the bullet. I then seat the bullet down and use it to push all the wadding down. This keeps the wad pushed against the base of the bullet to guard against chamber ringing.

I will be taking this to the range Wednesday again to verify that the really good group wasn't a fluke.

Based of a suggestion of someone else, I loaded 45-70 with 12 grains of Unique and I decided to keep the powder in the primer vicinity with 1/16th of a sheet of Charmin TP (yes 1/16th) pushed very loosely down to stay 1/4 inch above the powder (giving the powder plenty of room to slump). This produced a very even burn of the Unique and had enough hold on the case interior to keep the powder down there. Note that the little square of Charmin was pushed evenly down with a neck sized stick like loading a ML without the ball. My alternative would be like 1 grain of kapok fiber. Way back when I thought that dacron would work and then I found several warnings not to use dacron. YMMV but I hope you don't find out why it said to avoid dacron.
