Well I tried 2 brands today in that IAB Sharps 54.
Old Eynsford
And Goex both in FFG.
OLD Enysford grain consistency seemed finer than Goex.
I had some misfires.
Goex worked ok.
I hit the target at 50 yards and was pleased with my groupings.
But then I fiddled around, lost my zero and struggled a bit.
I think the Sharps itself got dirty and I lost accuracy.
But it was good practice.
Towards the end I had some misfires.
I took the cap off.
Waited to make sure it wasn't a hangfire. And when I opened the breech some powder had been burnt.
But no resulting bang.
There isn't any real gas seal.
I drop my conical in. Add my 80 grains of powder close my breech, cap and fire.
The conical is lubed.
But towards the end (shot about 20 times) I think I was running g into fouling of the nipple spark region.
So I quit.
I did take one shot using the top bead on my globe front site. Didnt drop as far as I thought it would.
I fo need more practice with it though.
My plan is to shoot my bear over a bait pile at 40 yards.
That should be attainable.
