I did this a couple days ago. I always hear, the 245gr Powerbelt doesn't shoot good in my gun, I use Such and such powder, tried the 295 powerbelts and they worked perfect and shrunk my groups greatly!

I decided to go ahead and use One rifle" CVA Accura V2", Two bullet weights "245 & 295" One primer, Hodgdons Big Three Pellet powder. The Big Three being, IMR White Hots, Pyrodex Pellets and Triple 7 pellets, all in 100gr Charge.


Making sure everything was equal i went and swabbed between shots for best accuracy, and mainly to be able to get the next bullet seated.

These targets were shot from 75 yards, and to be honest, No pellets offered me the accuracy that i desire and know the rifles can produce.

Starting out with 100gr IMR White Hots and a 245gr Powerbelt, Heres the result:
Now i did take 4 shots because shot #3 hit the bulls eye, i found that odd that it threw it off so far so i took another shot after cleaning and to my surprise, it hit down with that shot.


Changing targets, i again used the IMR White Hots, but this time the 295gr Powerbelt.


Having completed the IMR White Hot test, it was time to clean AGAIN, and load up with the 245gr Powerbelt and 100gr Triple 7 pellets.


100gr Triple 7 Pellets- 295gr Powerbelt.


Already i could see that both bullets with the Triple 7 and shrunk down greatly with just the powder change.

Taking the Quick Release Breech plug out and setting it up on the Best Gun Vise, i proceeded to clean the bore of the Triple 7 fouling. This powder produces some of the worse, hard to clean crusty crud ring i have ever dealt with. This fouling is baked on solid and took 4 patches to clean between shots where as the Pyrodex and IMR's only took one patch, using both sides.

T7 Crud ring,


Going over to 100gr Pyrodex Pellets and the 245gr Powerbelt i was very happy with the first two shots dead center of the bulls eye! Shot Three however wandered off.


Now switching over to the 295 powerbelt with 100gr Pyrodex Pellets, i did NOT expect this at all!


While most of the powders and bullet combo's produced decent hunting size groups, i didn't want to end it feeling poorly so i loaded Five powder tubes with 100gr Blackhorn209, CCI 209 Magnum primers and the 295gr Powerbelts. That actually is 5 shots, one shot apparently threaded into another hole and so it was impossible to figure out which hole it went into.


Now THAT was ending the day on a good note and feeling good about the accuracy it could produce.

It just goes to show you, One bullet may work great with one Powder, but the next bullet, may HATE that powder and not shoot for snot.

Muzzle Loading is a game of spending loads of $$$ on new powders, primers and bullets. Ain't Muzzle loading fun?!!?!
