Obviously even though a 50cal PRB is only about 180gr

It would be rather hard to get a chrono reading if the projectile never left the barrel don't you think.

There is a small pellet rifle and i think a pistol made by Pedersoli that uses a 209 for its energy source. It would make an interesting test bed for 209 primers.

Grrrrr, I don't have any RB's for the .50 laying around. Guess I shot them all up out of the old Hawk. I'll try it with a Connie.

Thanks for the link Ron. I'll read up some on it, and if you wouldn't mind, tell me a little about your setup and how well it works for you. Like I said earlier, it's not making a BIG difference, mainly on like the 3'rd or 4'rth shot I notice a lower impact point by between 1/8 to 1/2 inch at 100 which yes I know that aint much but it's enough to drive my OCD to the point of a fit!

Well i started out by purchasing a plug for the Omega, and some of the adapters. The adapters i prime using an RCBS hand priming tool with a RCBS #12 shell holder. The adapters i deprime by using the #12 shell holder in a Redding reloading press with what ever die is handy. Today a 223 die was used to deprime the adapters in the photo.










After a while i decided to modify one of my breech plugs to use the adapters. You can see in the photo, they are larger diameter than shotgun primers. In my mind, one of the disadvantages of the adapters is that they don't crush, beings how they are made of stainless. In order to stop blow by around primers, i like to see them crushed a few thousandths, when the rifle goes into battery. So what i did to my breech plug is not only make the diameter of the primer socket larger, i also made it deeper so i could utilize an o-ring, shown in the photo, which makes a good seal at the nose of the adapter, without crushing it..













It seems like the adapters will last for quite many many shots. They are very tough, not like brass cases. These here have been used around 25 shots each, and show no indications of failure. The only thing i do is clean the primer pockets once in awhile.

Can't really say i notice much difference between using shotgun primers or using the magnum large rifle primers.





To see if it could be done i also modified a couple of CVA plugs to use the rifle primers. The one in the photo has JB weld in the tool slot to help support the edge of the enlarged primer socket.

Why not just use the 209 primers for muzzleloaders? From what I understand they aren't as hot as even standard 209s but should be plenty hot enough for BH209. The reason they were made was just to solve this problem.

In my rifles, the muzzle loading primers are not hot enough to reliably ignite Blackhorn. Have read they are more than once, but they aren't. Shotgun primers are required in my rifles.

Same here. Tried them the other day actually when this was starting to run through my brain. (wife would say that's one short run!)
