Preston, take any 12ga load in the 8 to 9000psi range and if used in the 10 you'll have even lower pressures. I say 8 to 9 because then it'll be down to 7 to 8000psi. The chambers are a bigger diameter so there's more surface area for the pressure to exert upon so there's less pressure overall. I've used RD,GD, Promo, 700X, Nitro 100 - they all work.

Good evening to all
Believe it or not I still have not figured out how to down load Peters spread sheet
Does any one feel like down loading the spread sheet and email it to me it would be greatly appricated thank you in advance

did you down load the Adobe reader?

if you do- it should open automagically when you double click on it

emailing it won't help if you do not have a PDF viewer like adobe

I got it I figured it out wow Peter did a tremendous amount of research this spread sheet alone is worth my membership for a life time thank you to all of you that tried to send me down the right trail I think I am on my way when I figure out how to poast pictures I think I have some nice Parker's " in my world any way"I will poast them

PS kudos to Peter Lester !!!!!!!!

Alternative powders
 

Since PB, 4756, and 7625 are no longer around, but most of the data in the manuals and spread sheet lists them (basically outdated), has anyone found load data for other powders?

blue dot powder is a good powder for heavy loads in the 10 ga also green dot and red dot are fine for light loads ..herco poder is another good powder for the 10 ga...paul harm also has some differant powders he uses maybe he ll pitch in here...the herco load is on pete lesters loading sheet....charlie

Questions regarding the short ten list and the Hull abbreviations. Rem OS. What dose OS stand for. Rem whtlr. what dose whtlr mean and finally Rem blktr. These hull abbreviations are killing me trying to figure out witch components to use. Looking for a 1 1/2 oz load using Black rem hulls (once fired) from precision reloading and trimmed to 2 7/8". Powders available are Red dot, Blue dot, Clay dot, 700x andsr7625. I have Sp10 wads and Win 209primers and a brick of Fed 209 primers. Any good loads would be appreciated.

i forget the OS - the white and black lettering was on the green hull

i am not sure what if any difference is within those hulls

I have been buying the new green hulls

I think the only difference would be the height of the base wad of the different Remington hulls when constructing a load with the components in the recipe. Other than that I would just follow recipes for Remington and make load height adjustments as you go along.

I have in the past followed Paul's advice loading 12 gauge data in the short 10. Since I had 10 gauge federal hulls and Remington SP10 wads, I just looked for data in 12 gauge with the same components and primers used in the 8-9K PSI range and loaded up some 10 ga. shells I used 800x and they were similar to the recoil to RST's.

I prefer to roll crimp my 10's and then trim off 1/8 of an inch after firing to get an almost fresh starting point. I start off trimming 3 1/2 inch hulls to 3". (The extra 1/8 of an inch should really not raise pressures very much in a 2 7/8" chamber). I load these hulls 6 times until they are down to 2 1/4 inches, adjusting the shot cup filler accordingly, using 1 1/4 oz of #8 shot. Testing of each length of hull showed no negative effects in pattern performance or powder burn cleanliness. Of course, I do not know what effect shortening the hull has on pressures, but I keep these loads down to moderate speeds, have never had any signs of high pressure on the spent shells, and am happy to get 6 loads per hull.
