32-20 BP - getting there...

The last year I've been working on getting my 32-20 (and the nut behind) to consistently shoot , the delicate part being the cleaning between shots.
The smaller the hole in the barrel, the harder it becomes to get a consistent bore condition.  But I do believe I found the recipe.  

Target attached was shot last sunday at 100m with the BSA 12/15 rifle chambered in 32-20 (.308 barrel, 1-12 twist).

Load was 18.4grs of Swiss 1 1/2 Fg behind a 152gr RN .311  16:1 L/T bullet of my design with an overpowder card wad.

the 9 at  2 o'clock was the 1st shot from a cold, clean barrel.  Th 9 at 12 was the 2nd shot, and the other shots were fired after adjusting the tang sight a cat's hair down.

Yup, I came home happy...  For reference, the shooting was prone with sling, aperture sights.
Cleaning between shots with 2 wet & 2 dry patches, that seemed to work as it should.

Next step?  200 & 300m of course!

Shot some rounds at 200m today, I can confirm the JBM ballistics calculator is pretty good, 1 st shot landed in the 9-ring, rest were 9 or 10 except for a pulled shot in the 8-ring, the 'nut-behind' -issue.
But yes, the rifle and ammo will perform at 200m, no issues there...  Next step will be 300.

Thanks for posting your info.
Just acquired a 44 1/2 in 32-20
While I have not yet shot it, I'm looking forward
to getting a BP load that does as well.

What lube are you using.?

Just using a homemade lube consisting of beeswax and canola oil, nothing special. 
Don't forget my rifle has a  308 barrel, 1 in 12 twist, which allows me to shoot heavier bullets, so not really a standard .32-20.

Well, the short answer is - not yet.  I did shoot some targets at 200 - 2 encouraging sessions, 1 a bit disappointing.  Still trying to figure out the why for the disappointing session.
