Wow, that would mean a 12Ga slug has a TI much higher than I predicted. Guess thats why people use them for bear backup.

Well, anyway, it was a good discussion. I have a feeling I will not be able to shoot 150gr loads. Haven't tried it yet. Don't know too many people that has gotten good accuacy with the full house loads. I figure it will be around 130gr loads. I tried 777 when it first came out with No11 percussion caps, and it fouled my nipple so bad, I had to take it apart and cleaned wthin 5 rounds. Has anything changed with it? Figured the slower 777 would work better with my new 26" barrel. Thought maybe the 209primer will keep the thing from fouling the breech plug. I also have tried the powerbelts several times with my wolverine with no luck. Going to try 300gr SST's first then all the rest.
