doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com Need Help - Low Pressure Load Recipe

Hey all, say, I'm looking for a LP load to use for clays. The components I have are 12ga 2 3/4" Remington STS/Gun Club hulls, Win 209 primers and a jug of Promo powder. I can get wads no problem, but I'd like to use the above because I have a ton of them.

I'd like to load 7/8oz and really don't care to much about velocity, but would like to keep the pressure down to that 6500 to 7000 range.

The recipes on the Alliant site gives one at 7000psi, but the primer they state is the Rem 209P and according to the Alliant reps the Win primer would increase the pressure to around 8000.

So....does anyone have a recipe that would meet my requirements?

Thanks so much!

Greg

Greg, there's a STS/Gun club recipe at this site.

Promo is not a great powder for what you want. It is designed as a full target load at a cheap price. Look at Extra Lite or ClayDot or American Select.

In fact just go to Alliant Powder web site and pick 12 Remington Hull, select shot charge, primer and powder, all, to see your best options. I'd go for a 1 ounce load. The lighter loads tend to have more velocity to get proper powder burning.

1 ounce payload from a Remington hull in a CB-4100-12 wad on top of 16.5 grains of Clays powder ignited by a Win209 primer yields 1125 FPS and a chamber pressure of 5800 psi according to Hodgdon.

I agree Promo is not a good powder for what you want to do.

Greg,

As KY Jon suggests: "Promo is not a great powder for what you want. It is designed as a full target load at a cheap price. Look at Extra Lite or ClayDot or American Select."

I use Alliant Extra Lite powder to load 1/2 and 3/4 ounce 12 gauge loads and it performs quite well for in close targets. Pressures are down around 5000 - 6000 psi and speed at around 1300 per testing of my loads by Tom Armbrust.

I use a Claybuster CB0175-12 wad for the 3/4 ounce lead shot load with about 14.3 grains of XL powder and either a Rem or Win 209 primer. For 1/2 ounce lead loads, same thing but 14.0 grains of XL and I put a 1/8" thick card wad in the bottom of the shot cup to take up some space for nicer looking crimps.

I also load 12 gauge 2 1/2" shells using RST hulls to shoot out of my H&H hammer gun that has 2 1/2" chambers.

Nice mild stuff that gets the job done at short to medium distance targets. And actually, out of the left full choke barrel of my A. H. Fox early A, does reasonably well at distance shots too. It might not smoke 'em but a break is a break.

Hope this helps.

Sometimes you can figure out a good low pressure load for yourself, with help from Tom Armbrust. I came by an 8lb. keg of commercial grade Solo 1000, from a small shell manufacturer, some years ago. I had no way of knowing for sure if the burning characteristics were the same as the Solo 1000 anyone can buy. So, I loaded up a few shells with components I chose, just doing some extrapolating from the charts available, and flew them off the Tom. They turned out to be a pretty darned good low pressure load. Lower pressure than I needed, at about 5100 psi, AIR, which left me plenty of room to ease the charge up to get a bit more pressure, and more cold weather dependability.

Just a reminder that there is no danger in trying new loads, Greg, if you have them tested by Tom before using them yourself.

Best of luck, SRH

http://www.hodgdonreloading.com/data/shotgun just plug in your components. Try 12 gauge. 1 oz lead shot. IMR-7625 powder. Case type. I think You'll be happily surprised.

Low pressure 7625 loads are great if you use them in T-shirt weather. When you have to don your Long Johns they can give you squibs & let you down. I found this out in a duck swamp with temps in the low 20's. As I don't do clays except occasionally with a portable thrower for a bit of practise I have bought no more 7625.

Faster powders with a bit higher pressures suit my needs much better. When I pull the trigger I like the gun to go off with a solid Bang rather than a muted Burp.

I have had pretty good results with my low pressure 7625 loads in fairly cold temps, Miller. I've used them in the 20s temperature range, maybe even the 'teens, and have never had a squib load or a weak sounding one. Maybe it has something to do with wad pressure, or weight of shot charge, or primer used, or................?

I am not doubting that you have had issues, I've heard you say so before, just reporting my experiences.

All my best, SRH

I thought 7625 was discontinued. No?
