Took my Lyman Trade Rifle (54) to the range today. My goal was to find a good hunting load with Grafs 3F powder. I just bought a few pounds of it. Based on my previous results with Pyrodex RS in this rifle, I didn't think it would be very hard. The Pyrodex shot nice tight groups anywhere from 60-100 grains.
Today I started working up from 60 grains, 5 shot groups. 60 and 70 did ok, about 1 1/2" at 50 yards. But 80 and up opened up a lot. 3", then 4", and probably 6" for 100 grains.
I'm shooting roundballs with .018 pillow ticking lubed with olive oil. I tried a few groups with prelubed ticking also, but they seemed to shoot the same.
Not sure where I should go from here. Is there anything else I try to tighten up the groups with stiffer charges, or might it be that my rifle wont ever like a healthy dose of 3F? I've read that 3F sometimes calls for a tighter patch, but not sure I want that in a hunting load. Its pretty snug as is.
On a side note....I did pick up a pair of 1858 Remingtons over the Holidays and they sure shot wonderfully today! Worse come to worse, I have several pounds of Grafs 3F to burn in them!
