I have not used my smoke poles much but need to get them ready for hunting in December.

I am curious, for those who shoot a lot which standard 209 primer would you run? It seems like milder 209 primers would work better. I have a bunch of strong primers but for weaker primers I have Remington *69 primers, which are suppose to be weaker for 410s. I have a whole pile of CCI209 and some Cheddite, which are both suppose to be weaker primers.

Is what they say about weaker being better for crud rings?

Also, I ended with an Austin Halleck inline and picked up both the 209 and Variflame Large Rifle Primer kits for it. If I run 209 then the same primers as the other inline would probably be the way to go but would the Variflame help with crud rings? If so then running a hot Win primer be better or worse?

Thanks
 
I found that weak primers caused partial ignition with 777, particularly in cold weather. I switched to hotter primers and the problem was resolved. Regarding the crud ring, some sabot bullet combinations seem less sensitive than others.
 
I get the ring when using pellets not with loose powder. When I used 3x 5050 pellets it really built up. The gun I use most is only rated for 2x 5050 pellets and I can get 10 or 12 shots before reloading becomes excessively difficult
I got better accuracy using milder primers. Can't think of the name offhand but they're for inclined. Black primer cup nickle primer. The packaging is orange with a black tray so I'd guess federal product. My 209 shotgun primers all had bigger groups and the cheddites that I use for shotgun I found were backing out of the cups in several inlines
 
I use bulk powder (78gr weighed). Clean after every shot at the range. No problems so far. Good accuracy with Hornady SSTs.
