I have an older "Country Boy" 50 caliber in-line muzzleloader produced by Navy arms in the late 80's or early 90's.

It was manufactured with a #11 nipple in the breech plug as the ignition source. I discovered last year that my Traditions breech plug, equipped with a 209 nipple, fit into this Country boy. I decided to try a 209 ignited low power charge in the Country Boy and it fired fine.

I tried 3 more shots with a full charge of 100 grains of Triple Seven and it fired and printed fine.

Do you guys think I am risking any issues by going this route of the 209 ignition instead of the original #11 ignition? The # 11's aren't always as reliable as the 209's , but if the general opinion here is that I should lower the charge to say, 80 grains, that would make sense to me.

Opinions?
