Mike AR, I think what you were seeing in the receiver area was due to the problem you described with the rifle's fit. Most any rifle will have some degree of blowback and fouling in that area regardless of primer used. Primers are not standard in dimension though so a tighter fitting primer might save you a bit of that grief. As to inside the bore - you are very likely to have that internal crud ring with Triple7.

Been using the Winchester standard 209 primers since I started using an inline and never had any problems with them. I have used them with pellets and loose 777 and have nothing but praise for how well they work IN MY RIFLES.

I have heard for awhile that cooler primers seem to work better with 777. Anyone have any info about using them with Black mag3?

I shoot Black Mag'3 with the .25ACP conversion using Winchester small rifle primers which are pretty cool compared to the 209 primers. I have very good results with BM3 using the cooler rifle primers. I also know that standard #11 percussion caps will ignite BM3 just fine. It is easier to ignite than 777.

Wow guys thanks for the response. I did figure that different primers ignite and burn at different temps. thus would burn the powder at different rates of speeds. The hotter the primmer the faster the rate of powder burn. I just wasn't sure how much difference there was in primers. Thanks again Mike

Can any of you experienced in-line guysor re-loaders list some of the different 209 primers on the market made specifically for muzzleloaders without too much trouble? And, could you list them in order from hottest to coolest? And, how do you know which are hotter or cooler?I'm assuming the list would be short but don't know.

As mentioned before. There are some primers marked for muzzleloaders that are just standard shotgun primers repackaged so it is a little confusing. Remington just came out with a primer that is reduced power (actually the old .410 primer from information I have been able to get) Now called the Kleen-bore or something like that. Winchester has marketed a black powder primer for some time that was really just the standard shotgun primer repackaged and marked up in price. From what I remember Federal 209 primers are the hottest, then Winchester and Remington standard 209 shotgun primers, then CCI, then then new Remington Kleen-bore then the new RWS (Dynamit Nobel) 209 which I cannot find anywhere that has been made specifically for muzzleloaders. I may be a little off on listing from hottest to coolest but this is close. Anyone else want to help?

I do not believe the new Kleenbore ML primers are anyway close to the old Remington 209-4 primer. The 209-4 is a whole lot cleaner and seems to be even cooler than the new designated ML primer.

The new Kleenbore ML does not appeal to me at all because of price and the amount of material that it leaves in the breech area. I am forunate to still have 2/3000 - 209-4's left so that will take care of me for awhile. Another cooler 209 that I have used with really good luck is the Cheddite 209 - I think it is a tad cooler than the Winchester 209, but it is strong enough to start t7 pellets on really cold miserable days. And most important for me shooting Remingtons 700ml it is not very dirty. If I run out of 209-4's the Cheddite would be my next move.

SL, are the Cheddites also a bit smaller physically? I've meant to try some of those for a long time but keep forgetting. Fancy that!

Age - it does take its toll & I should know...

You know UC I use them in all my trap shells, Remington, AA's, and even some odd ball stuff andthey work just fine into the primer pockets. In the ML's they fit great and come out easy. I have not mic'ed them but tey seem pretty comparable to the 209-4's.

I have gone through maybe 30,000 of them shooting trap and I can not remember a misfire due to the primer, I can rememder several misfires with the bb's running out on the ground - but that was the loaders fault, I mean the mechanical loaders fault, for not putting any powder in the shotshell, Gees come to think about the loader has done that in my ML once or twice also.

They really seem to be a cleaner 209 also...
