This one guy at Kames said that if you use a 209 primer then it might effect your accuracy because it has too much of a blast. So..when the trigger is pulled, (if your using 777 pellets) the blast goes throught the holes in the gunpowder and hits the rear of the bullet - displacing it - before the gunpowderevenignites, effecting your accuracy. He told me to use a 410 primer instead (for better accuracy). Is this true????

777 suggests using 209 shot primers with thier pellets. However I have used pryodex and clean shot pellets with musket caps and had no problems.

Nope. I've got an Omega and I use the 25 ACP ignition. ZERO difference in group size between Win 209 and Win Small rifle primers. The guy you talked to probably got that from PR bullets who sells 25 ACP ignition systems and claims better accuracy. It's a sales gimmick.

Yep, can be true. Just cause one guy had one experience on one gun, doesn't mean much.

But they are designing the hole to control this I have noticed. I know the revolution changed its breach from when it came out due to this. so for some guns designed to keep the spark down, you might be hurting yourself.

I have only experienced crud rings on T/C's, never my knight. The believe which seems pretty valid is that in some guns, the initial impact of the 209 pushes the load up before igniting causing an air gap.

I have heard the same thing. In my Black Diamond XR I really do not get a "crud ring" like many people talk about. Sure I get fowling, and lots of it. You should see the scope at the end of the day. But a crude ring that is next to impossible to swab out... nope.

Today, I just bought some Winchester 209 primers at Wal Mart. According to the package they are, "WINCHESTER 209 Primers for in-line muzzleloading rifles." Code # WML209 (instead of W209 like before) $3.95 for 100 of the primers. The new REMINGTON primers for muzzleloaders were $5.95. Also on the back of the Winchester Primers they tell you that nothing in this, "Non-Corrosive and non-mercuric, these primers contain no ingredents that cause rusting of your barrels."

According to the sales manager of the sporting goods, they were told, the new winchester primers are low powered and will put an end to fowling problems and all the other complaints made by muzzleloaders. I can not wait to try them out.

And I got a number of different projectiles to try out including the 200 grain Shockwaves with the blue sabots, some Spitfire 230 grain HP's , and a bunch of other stuff. I should never go into those kind of stores...

Actually 4 guns total. I just didn't mention the 3 guns I used #11, Musket cap, or 209 primers in. Of course that was back before all this primernonsense started. Only difference I noted then was a slight POI shift.

I don't know if this is true or not, but years ago, I was using loose Pyrodex with a nipple adapter on a caplock rifle that took small rifle primers. After shooting and chronographing a ten-shot string with this device, I removed it and installed a regular nipple that used No. 11 caps. I then shot another ten-shot string, which I also chronographed.

Not only did the ten shots fired with the regular No. 11 caps group much more closely (100 yards) than had the ten using the SR primers, but the extreme variation in velocity dropped from 110 FPS to just over10 FPS.

So, in this test, the less powerful primers worked a lot better!

What about using #209/.410 primers ?

Wasnt' pointed to you or anyone else, just stating the experience I had. Congradulations on not seeing any issues

Kevin.. that's what everyone was using or at least trying to get their hands on. Remington and Winchester saw a real need out there for a low power primer and have produced it. Remington is much more expensive the Winchester but we will see how they work.
