Will a #11 percussion cap fire Pyrodex pellets in White rifles or do I need to use 209 shotgun primers?
The #11 nipple-breechplug in a White designed rifle is short, with less than 5/8 inch between #11 cap and the powder charge. The #11 nipple with cap installed is also very nearly impervious to weather. The combination yields good results with pellets. Ignition can be enhanced by switching to a musket nipple-breechplug, which is almost as good as the #11 at keeping moisture out of the powder charge on wet days and comes very close to duplicating the performance of the 209 primer. The 209 conversion ignites the pellet even better yet, but at the sacrifice of weatherproofing in slam-hammer guns like the Whitetail series or Super 91 and M98. The new ThunderBolt locks the 209 primer in place and is once again quite weatherproof.
