Chuck, do you have the quick access feature on your old PW? This is one accessory that is worth the money. You can change shot and powder bushings without draining the reservoirs. I have converted all of my old 800Bs to this feature. It makes switching from one ounce to 7/8 ounce loads a piece of cake. I don't know how much it costs but it is worth every penny. If you forget what you have in the bushing cavity, you can remove the cap,look down at the bushing and read the number off the top of the bushing, change it if you wish, all without touching the shot or powder.

WW 209 primer
CB 1100-12 wad
23.5 grains of IMR 7625

3500 psi

This works well at sporting clays and you can hardly feel the gun go off. I shoot it through Damascus and Twist Parkers.

I too started using 7625 this summer with great results. American Select is a very clean powder and works well with 1 oz. loads. Isn't there something out there called Promo that is loaded like Red Dot. It seems Red Dot has a number of imitators, that should tell you something.

Murph,
Just my .410 Plat 2000 has the EZ access top plate and short hoppers. The 12g 900 has the standard top plate that requires draining the hoppers.

eightbore, I suspect there isn't a great difference in brissance between RD and Nitro 100. I base that conclusion on the charge wgts. being similar for any given shot wgt. and velocity. The major difference seems to be that Accurate is listing a lot of low pressure loads (including 3/4 oz) and Alliant isn't. I load a lot of Promo for skeet but right now loading mostly Nitro 100 1oz. load for my delicate and beautiful Flues trapgun. I save the 7625 for 16 ga.

Similar charge weight to make a similar velocity will have absolutely nothing to do with the burn rate of a powder, burn rate being the factor that determines suitability for specific loads. Red Dot and Nitro 100 could have similar burn rates, but it would be a coincidence unrelated to the weight of powder required to propel a shot charge at a certain speed. I do agree that Alliant is a little short on low pressure 12 gauge light loads.

2003 Accurate reloaders guide equates Nitro 100 with Red Dot, Solo 1000 with GD, Solo 1250 with PB as "comparative powders" (probably means comparable powders). Equation must be based on relative speed. But I stand corrected.

Promo is Alliant's bargain powder. Loads the same as Red Dot but density is purported to vary from lot to lot. Don't rely on a bushing alone for powder drops, weigh them again when opening a new container of Promo...$77 for 8#.

Two of the advantages of using a powder like Nitro 100, rather than 7625, PB or some of the others, most of which cost more per pound than Nitro 100, are lower cost and less recoil. Using 24 grains of one powder vs. 15 grains of another will produce more recoil. Not a great amount of difference on these very pleasant loads we're talking about here, but I have used the others and can feel the difference.

Shame on you, Jim. You know very well that weight and velocity of ejecta are the only significant indicators of recoil and weight of powder charge does not enter the equation. Red Dot, Nitro 100, PB, and 7625 have very different burning rates and are not suitable for all the same loads, even though they may be suitable for some similar loads. Charge weight is not a factor in determining powder substitution except by coincidence. Should we change the title of this thread to "Old wive's tales of reloading"?
