BH 209 with plunger style inline?

Can Blackhorn 209 powder be used in a ?plunge style? open breech inline?

My current set up: 50 caliber Knight Bighorn (2002), 90 gr triple7, 290gr hollow-point power belts, Winchester 209 shotshell primers with NO plastic jacket.

I've searched online and find the generic answer of ?no? in ?plunger style? inlines because of possible blowback. I also find people saying that they have no problem using it in those types of guns and that 777 gives just as much blowback.

I have a good muzz elk tag this year and the benefits of BH209 are very intriguing. If I am going to switch loads, now is a good time.

What do my MM friends think about BH209 in a Bighorn?

heartshot

western powders does not recommend it in an open breech muzzle loader. I know another fellow on another forum tried it in a tc black diamond and had to pry the primer out of his forehead.

Not safe to use BH209 in the plunger style inline and thats all of them.

Thanks for the replies. I will stick with the 777, it has worked great in the past.

I was on a muzzle loader kick for some years but it has been 5 years since I had a muzzleloader tag. Question: Is 11 year old triple seven to old? Does it loose its oomph over time?

Get some new powder T7 only list one season. so shoot it our loose it.
