I first started out with the deer creek, got good groups, nothing i was to happy about, went back inside, grabbed the traditions kentucky flinter and was Really happy with the groups i was getting, even though i forgot to use pillowticking patches
Beautiful cloudless, almost windless day, 56* "Nice T-shirt weather"
Loaded up the CVA Mountain Stalker .50cal, 100 grains Pyrodex Select "My cheek hurts" 295 grain Hollow Point Powerbelt "Chapbelts, Chap donated them to me"
Found a 1.25lb Plastic Icecream container, Took everything outside and went and set the container up "58 yards" and packed it with a mixture of wet/almost dry sand.
Went back to my shooting Log, Capped, Aimed and squeezed the trigger and i see the container jump in the air and tip over. Went and dug through it and found a couple small fragments, then dug deeper and found the entire bullet.
Loaded up again with 90 grains pyrodex Select, same bullet load, same yardage, Capped, aimed and fired, Bullet hit 3/8" to the right of the first shot, Dug though and found the bullet and it had just one small section of Pedals missing on the corner. Overall i was happy with it.
Next shot was with,... Can ya guess? Hmm? Anyone?

80 grains Pyrodex Select, same bullet,same yardage.
Aimed,fired and again saw the container jump in the air and tip over. Shot #3 hit just under a 1/2" high of #1 shot. This Mtn. Stalker is one hell of a shooting rifle if you dont mind the sore cheek. I blame my big head, Not the rifle
I would say it's safe to use 85 grains Max with the 295 grain powerbelt if you are shooting out to 100 yards and want it to hold together incase you get a close range shot.
Take a look at the 100 grain charge Powerbelt, Can you imagine what this bullet would look like if i were using that 150 grain mag charge?

I'd have to be dressed in a Flax Jacket to be protected from the fragments.
Top to bottom:
100 grain Pyro Select " Fragmented"
90 grains Pyro Select " Slightly fragmented"
80 grains Pyro Select " My recommended charge, and the bullet that mushroomed perfectly with no issues"
