    I had 3,000 CCI M (red box) gave to me....I currently load 16 grains of 700X in a STS hull with spolar wads....They crono @ 1,155 fps....If I use the CCI M primers how much will I have to reduce my powder charge to stay in that 1130 to 1150 fps range...

    What do you all think of the CCI primers in general?????

    Thanks

    Shawn

    Go to the hodgdon site and get the correct recipe for your components. Anything else is going to be a guess...

    The CCI 209M primer is a favorite of mine for certain loads. They work rather well in cold weather and in larger capacity hulls like the Federals. I've never had any issues in the loads I've used them in. I'm sure they will usually increase the pressures over most other primers. You neglected to mention which primer you are currently using, and what shot payload. I would not expect a major increase in velocity using them. Most often, it seems that the pressures can increase or decrease, but the velocity might not change all that much. I would strongly suggest that you contact Hodgdon and get their take on such a substitution. You could potentially increase pressures by several thousand PSI by swapping primers. That could put you way over the top.

    My best recommedation would be to use the CCI209M in a load that specifically listed them. If you must use them with your existing load, you might consider dropping the powder charge, not because of velocity considerations, but because of pressure concerns. I would suggest limiting your pressures to less than 10,000 PSI for loads you shoot "volumes" of. The best way to know what would happen with your components, would be to send some out for testing. Short of that, a call to Hodgdon is the next best option. Just remember that they might be doing the "S.W.A.G." routine as well. It would be better if they have data to support it and I'd be sure to ask that question.

    I wouldn`t think twice about useing them for rifle or pistol, and normally do, but I have to say last summer I was a bit unsure when I switched from WW to CCI for shotshells. Just don`t like to change what works I guess. But so far they seem fine, always go bang in a few different guns. Time will tell.

    CCI 209M are magnum primers for heavy loads and slow propellants, water-fowl loads. I would call CCI before I used them with a fast powder. Wayne
