Bad time to start reloading 10 gauge?

If you weigh the amount of red beans/ for instance, it takes to fill the hull, it may have a significant impact. Unlike a light cork cushion wad, the beans actually have a lot of space which the shot occupies, so it takes more than you would guess to really fill the shell. I don't remember the numbers, but I loaded a hull normally and added enough beans mixed with the shot to get the proper length and the combined weight of the beans sdplus shot surprised me. Be nice if someone loading these would have them pressured tested against a shell with a cushion wad filler and a simple shorter shell with the base load.

You may be quite correct in your assumption . But I’ve had no issue in over ten years of loading this stuff with various fillers . What you Need to do I would think is weigh the cards you’d normally use vs whatever other thing you choose for displacement . While I say I’ve had no issue it only takes once , I may blow one up tommorrow with the same load and no longer be of the living but I seriously DOUBT IT

Looks like Midway has Longshot and a few other powders in stock this morning.

SR7625 is “THE” 10 gauge 2 7/8” powder . Unique and Universal Clays can be pressed into use for decent 1 1/4 to 1 1/2 ounce loads . And of course Red Dot for 1 1/8 ounce loads .

What kind of pressures does the SR7625 generate in 1 1/4 oz. loads?

IMR SR7625 was discontinued at least 5 years ago.

Sure was and I bought all I could get my hands on hence my reference to using Unique and Universal Clays . I’ve still got close to 16 pounds of SR7625 .

I dunno I got the load from a Ross Seyfried article in Handloader about twenty years ago .
