Anyone wanting to get into 10 ga reloading might look at my advert to sell an as new MEC press complete with 2-7/8" short kit AND 500+ SP-10 wads in the Members Forums.

REALLY glad I found the guy in Canada with a ton of SP-10s a while back. I bought a bunch and I believe Craig did as well. BP has their BP1044s in stock at $25 for 250. I'd be inclined to try'em before Ebaying at $75/250. I use BP wads for nearly every load I shoot in 12,16, and 20. Never any issues, work well for me.

The BP1044 work well too.

Haven't tried the "new" ones, I shot some of the 10ga. wads they had a while back before they disappeared and they were just fine. If/when I run out of SP-10 you can bet I'll be getting some of the BP 1044 before I pay crazy money for the old Remington wads.

OK, I finally have my supply of primed Cheddite hulls and BP wads.
What is the best powder CURRENTLY AVAILABLE to load 1 1/8 ounce target loads in my old 10s?
I have Perfect Pattern, which seems too fast, and Winchester Super Handicap, which seems too slow burning.
I also have some International.
Any suggestions?
Most of the powders in the spreadsheet seem “unobtanium.”

Hodgdon International is very close to Alliant Green Dot. I would not be afraid to try 22 grains of International with 1 1/8 ounce lead. It would be an untested load if you decide to try it but I believe the risk of something bad happening in a sound gun is negligible.

Tested load
 

Here is a load I had tested at Precision if it helps you out.

Wow!
That is as close to what I am looking for as anything else. The only difference is the wad.
And that the pressures we are dealing with, that should be absolutely no problem, I would think.
Tell me, how do they shoot, and what do you shoot them in?
Presumably, it’s in guns approaching 9 pounds, so the felt recoil should be negligible.
Thanks a million!

I've got a few different 10s all with Damascus barrels I shoot them in.Seems like a mild load.I haven't patterned them but shot skeet with them and worked good.The bp1044 wads will likely have a little more pressure as the crush section is somewhat stiffer than the sp10 wad.The old sp10 wads had a thinner built crush section than the newer ones do and as a result created a little more pressure also.Tom Armbrust will verify this with tests he has done for me.If you were to substitute a ww209 primer for the cheddite primer,pressure and velocity would both likely be a little lower as the ww primer is a little milder.Ive got 1 1/4 oz loads I've had tested using long shot with similar velocity but lower pressures yet.I think I've posted some on here in the past.Jeff

It seems like pressure is hardly an issue in that load. In fact, a little more pressure might make it burn cleaner. Is that possible?
