Federal 7/8 loads?

[Paul Harm]

Reloaders like to shoot for something under 7 to 7500psi. Don't know where that number came from. I try to keep under 7000psi - why - guess because it sounds good , or maybe because I shoot them so much it's less strain on the action and old wood. Kensal said it all, how many shells went through those old guns that were " magnums " and didn't blow up. I'm not saying to tempt fate, but 7500 to 8000psi isn't high. I'm sure you'll be fine. But you know Gary, we are on the reloading forum, so there's a easy way to fix your problem - start reloading and quite worrying about factory ammo.

The new Federal 7/8 ounce loads at 1200fps, now that Federal proclaims that they are 7500 to 8000 PSI, are the greatest thing we have found to shoot in any gun for high volume 12 gauge shooting. For everything else, RST is the thing to use. By the way, the Federal load is not exactly new. They have made a low velocity 7/8 ounce load for cowboy action shooting for years. However, it has been about impossible to find on the wholesale market. By the way, have you ever heard of a cowboy gun blowing up because of use with store bought shells?

There is one way to know for sure exactly what they are .send them in to be tested , Probably cost you about $50.00 bucks . If where me and I wanted to shoot them all the time , Thats what I'd do .There is only one problem with that if Federal decides to change their load you will not know it .

Like Paul said the only way to know for sure is to reload.

Reloading is the only way to go.

24 GRAMS IS .85 OUNCES
7/8 OUNCE IS .875 OUNCES

I REALLY LIKE THIS LOAD. FROM THE IMR LOADING BOOK (2007, PAGE 38).

3700 PSI !!
1200 FPS
WINCHESTER AA
24 GRAMS SHOT (.85 OZ)
24.5 GRAINS SR7625
WIN. 209
CB1100-12 WAD (Claybusters)

Jerry, How can a load with 24.5 grains of SR 7625 equal 3700 psi?

I agree - sounds incredible Dave

but the current load chart says the same thing - page 11

Dave,

It is just the properties and burn rate of SR 7625 I guess with so little shot. Dan Morgan who works on Damascus barrels told me about the load when I had some bad dents removed from a Damascus tube and I was down to .022 thickness at that spot. If you get the IMR load data book there are over a dozen loads with 24 grams of shot from 3000 psi up to the highest of 5400 psi for a humming along 1250 fps.

When I shoot 12 gauge AA hulls in my 10 gauges using Gauge Mates, regular loads ruin the hulls where the cases split in the little gap of the Gauge Mates. When I use the 24 gram 3500 psi loads, the hulls do not split in the Gauge Mates. Thus I can tell they are very low pressure. I can't copy the book at home but I am sure someone else has the IMR book. Do you have one by chance? Look at the Winchester AA loads.

Thank You Gents, I load alot of 7625 in my 16 gauge and light 12 gauge loads. I will get out my IMR loading manual and check it out. Maybe I will load a few just for the heck of it.

After about a million members on this forum told me to start reloading... :-)
I finally jumped in.. picked up a used Mec Jr from a member on this forum.. so will be reloading now. in the process of acquiring the components now.. and doing a lot of reading (research). Going to be using 2 1/2 hulls left over from all the RST's I've shot. Got the short kit for the 2 1/2's and a recipe for approx 6500 psi for 1150 fps. 1oz 8's. that will get me started and i can experiment further down the road as i learn more.
Thanks to all for your input.
