I just shot my Lyman GPR kit (1-60" twist - .54 CAL) for the first time and it was a blast!. It took a while to get it to fire. I think the tube connecting the cap and chamber was a little clogged. I tried cleaning it out, I wasted several caps and I finally removed the nipple and put a small amount of powder in there. That did the trick! After than it didn't misfire once, not once!
I was amazed how accurate it was. I used 777 and Pyrodex Select (that was all I could find). I played around with the powder type, load size, ball (.530 & .535) and patch. I found it real hard to load the .535 balls, so I stayed mostly with the .530 balls. I assume as the gun wears in that I'll move to .535 ball, but we shall see. I also found the Pyrodex a tad more accurate that 777, but both worked well. The gun also seemsed more accruate at lower charges (60-70) vs 90-95. I though maybe the larger ball and higher charge might solve that issue, but forgot to check.
Unfortunately, I didn't like the sights on the gun at ALL!! I used the adjustable rear site that came in the kit beacuse the fixed one was too loose to use. Has anyone used a different sight on the Lyman GPR riffle? I see that the Lyman offers a couple options. The one with fibe optics looks interesting. I'd like some opinions.
I'd also like to know if anyone uses "loaders"? I plan to use the riffle deer hunting and I can't see my self fumbling around with the powder can, measures, patches etc, while hunting. I see on line that they have some "loaders" that hold the patch ball and powder in a tube. Do these work well?
I had a great time!!
Thanks for all your help building the gun!!
