i too use 700-x and have not had a "dud" with it with 100's of shots, love it for 1 0z and 1 1/8th oz loads, 18 to 19 grs of powder, scott

What do you think
 

This Green Dot load is listed in the current Alliant Reloaders Guide, it is for 3.5" Federal shells. To those who reload for the short ten what do you think about backing the powder off about 10% to 26 grains in a Federal hull cut to 2 7/8"?

Along with 10% less powder I would think that less filler material being needed would also decrease pressure slightly as well (going from 6 .135 cards in the 3.5" to a single .250 16ga fiber filler in the 2 7/8")

I was thinking about trying this in a Twist gun and maybe send the loads to Precision Reloading for analysis of pressure and velocity.

What do those of you who reload for the Short Ten think?

Pete,

A roll crimp is great for pressure reduction.

Less "ejecta" should lower pressure.

I would start with a "cool" rather than a hot primer.

Mark a roll crimp would be impractical as I would use this load for volume shooting (crow hunting). Good point on the primer, a Remington STS or Fiochhi 616 (209 type) looks like it would bring pressure down further.

I got out my scale and weighed an SP10 wad and the 16ga .135 cards and a .250 16ga fiber filler wad. Ejecta (including powder) is 6% less for the 2 7/8" load. So we would have a 10% decrease in powder, 6% decrease in ejecta and it's using a cooler primer. My guess is this load would be in the high 7000's PSI but that is nothing more than an "educated" guess. I think might try these and call Precision to find out how to go about getting a 5 shot ballistic test done to find out for sure.

I think I have read all of Bell's work and I trust him. He has shot BP loads that register 8,000 psi.

I have tied a gun to an old tire and touched it off with a string. But I was shooting a Ross Straight Pull MK II. Works fine. So did the rifle.

In one of Bell's studies he took a damascus Elsie and honed the barrels paper thin, and then he fired off the proof loads. No problem with the barrels. I think after a few shots the wood suffered cracks. Proof loads are heavy 18,000 psi shots.

While we are all concerned about shooting damascus barrels, after all we've all been warned a hundred times not to, but still; I trust Bell's work, and he says that when using standard loads they are safe to shoot. He even shoots heavy loads with little or no effect. I don't think that 8,000 psi should be a problem...just be careful of obstructions in the tube.

In the old days damascus barrels were considered better. Parker did proof their barrels.

I have always wondered if proofing a barrel also weakens it so that it will let go later on. Apparently this is not an issue, but it doesn't seem logical to me.
