Lyman Rifle
« on: May 19, 2013, 07:45:47 PM »
Hello all I just got a Lyman Rifle with a 32" barrel 1/60 twist 50cal. What kind of groups are you getting or what should I expect with this rifle at 100yds. I have 2&3F Black.

 TIA Birddog

Birddog,

If you get the right combination of patched round ball and powder charge it will be accurate. However I believe your expectations concerning distance & group needs to change. You sound like a center fire rifle shooter.
Think get closer, think where can I make my one shot go every time.  ;) your a muzzleloader hunter now. It takes a different mindset.

Of course I'm not a target shooter. I'm a hunter pure & simple.  >:( so I think different than a paper puncher b ;)

There are people that shoot matches with black powder guns, just not me.

what should I expect with this rifle at 100yds.

The limiting factors are the open iron sights and the shooters skill.
I'll presume it's the GPR, the slow twist is designed for shooting Ball. Conical projectiles require a faster twist to stabilize properly and that's the Great Plains Hunter rifle with 1-32.
 
That said, once you've done proper load development with the variables of Ball size, Patch thickness and find the patch Lubrication Properties that your rifle likes with your loading technique,,
(Off Hand)
,, the average shooter can get 8" maybe 6" group at 100. An experienced shooter in good physical condition that spends time Practicing and keeps his rifle and gear in good condition can bring that down to 3". Get the thing on a bench and you can get it down to 1 1/2-2",
Again it's the sights, the shooters eyes and practice.

But 99% of shooters can't see the sights well enough to shoot that good.  Heck 99% of shooters can't shoot that good with a scoped deer rifle off the bench.

Swampy is right about the sights. My groups got bigger and bigger off of irons. I'm slowly getting the ones I shoot switched over to peep sights and they are shrinking back down.
Every rifle is a little different. Generally the gpr I have owned like 50-65 gr 2f for accuracy. The one I'm shooting now likes 55 gr 2f goex, .490 ball, cardboard over powder card and a .015 patch lubed with beeswax/alox. 50 gr is just a little bigger so I go the cheap route and skimp a bit. If I do my part it will be within 2" at 100 until the barrel heats up. With standard sights it doubles.

Hmmm. I keep meaning to try a lighter load in my GPR. I had (still have actually) a little .50 carbine that likes 50 grain loads but I have always shot 90 grains of FFg in the GPR. With a .490 LRB, a 0.030 fiber wad over the powder and a 0.010" patch. At one point, I mounted the Lyman aperture sight but could not get good groups with it and went back to the buckhorn rear.
