REM-870/.735 Round ball/Rifled Choke

mehavey · October 12, 2017, 09:45 PM

For the search engines:

Ran:
- Ran the Bess 735 ball. Never tried small as intent was to use same ball as the Bess
- Ran pure lead & Lyman#2. Settled on pure lead/600grs/1⅜oz
- 34 to 40 grains/BlueDot. Settled on 38 grains/1,153fps. Recoil just a big push vs a nasty snap with commercial 1oz/1,610fps Foster slugs
- Sprue up, down, and as-is (vs) smoothed. Settled on Up/as-is
- Discovered that the cushion wad was was a PITA to get past the case mouth -- until I found the MEC-600 Jr's wad guide fingers worked perfectly fine using the press as normal
- Also discovered that the load shot rather high/past point of lowering rear ghost ring at 50yds. Hence put on an old Weaver 1-3X scope that I had in a drawer.
- RE-discovered the Group Law known as "...there's always shot #5..."

Sheesh. Got yourself a thumper there. I have a .69 cal round ball mould Ive been wanting to tinker with in 12ga. Probably have to use some type of cup wad. Good times.

I use a 0.690 round ball (lead) and it is good for 2" at 50 yds.

I haven't had the opportunity to go to 100yds yet, but it is in the plans.

You could try a drag tail like the brenneke uses. Bore a small hole in the base, hot glue an inch or so of para cord, add to the war column. No destabilising roll.
