My GPR is a shooter

[irataylor]

Took my GPR to the range today, my second time
shooting the rifle. I have added a RMC vent liner.
Really makes a difference. I am working up a hunting
load to be used this Thanksgiving. My first three shots
were virtually one hole. My fourth shot made the group
1 1/4. I pulled the last shot getting a 1 1/2 inch group
at 50yds. 530rb, 70grs FF with a 0.18 T/C pillow ticking
patch. I am pleased that my first shot grouped with the
rest of the group. I am cleaning between shot using a
damp Windex patch followed by a dry patch.
I will continue working the load next weekend at
100 yards.

I have a .54 cal. GPR flinter that shoots excellent at 50 yards with .530 ball, 80 grains of FFg Goex and pillow ticking with moose milk. At 100 yards, I kept everything the same, except I increased the powder by 10 grains, to 90. Using the same sight picture, I got the same point of impact. With the right load and a good set of eyes, these GPRs with the primitive sights will give a scoped 30-06 a run for the money at 100 yards. You just have to do your part. Your GPR will do it :thumbsup: .

Thanks for the info I will try increasing
the loads and see what happens this weekend.

I totally agree and I have a nice scoped 30.06 with all the bells and whistles.

Back when I got into muzzleloading I played around with a lot of different rifles and wasn't really very impressed.

And before I got them, I had my doubts on my .54 Lyman GPR-H and my .54 Cabela's PBR, but each have long since proved their worth

What is an RMC vent liner, and where do you find them?

The ventliner is coned and the vent
hole is larger. You put it in
with an allen wrench.

Thanks!
