You just can't beat a GPR

Had my Lyman Great Plains Rifle out again yesterday (.54 caplock from a kit) for the first time in several months. I'm tellin ya, it can't be beat. Anyone thinkin about getting into blackpowder should get one.
I was with some friends/family who had been wanting to see it so we took it down to their creek. I hung a paper plate in a tree (so we were shooting into the bottom of a 40ft creek bank/hillside) and we stepped back about 40- 50 yards. I took the rifle out, let em all take a look at it. Showed em how to load it and then prayed that the sights were still on....
BOOM!......smoke cleared, and from where I was standing you could see the hole right in the middle of the plate :D
I ran a patch down the bore, and asked if anyone else wanted to try, only one guy would. He shoots/ hunts a lot so I loaded it up minus a cap. Explained the double set trigger and then handed him the rifle and a cap. He shouldered it, tried the balance a little bit then BOOM....another hole in the plate about an inch above my shot. His response? "That doesn't kick at all"
I put a couple more through it and it was shooting great as usual. Its such a comfortable gun, aims naturally and soaks up the recoil so that just about anyone could shoot it. I was just using a .530 ball over 60 grains of FFg Goex, a very accurate load in this gun. ( makes a can of powder go a long way too)

So then I decided to try some experimenting. I'd heard that a slow twist barrel won't accurately shoot conicals (I still believe this, but I think when folks say accurately they mean match accuracy). I'd also heard that hunting class loads give you a sore shoulder.
So I loaded it up with a 435 grain maxi hunter made by TC over 60 grains of powder. Shot it at the plate, it hit 2 inches lower than the ball, but windage was right on and it punched a clean round hole. No keyholing.
So then I bumped it up to 80 grains of powder under another maxihunter and decided to do some ballistic testing on a log that was down over the creek. BOOM....you notice the recoil now, it raises the muzzle some. But its not painful in any sense of the word and I was only wearing a long sleeve shirt and light jacket, no padding.
It hit right where I was aimin, just like the patch an ball I could call my shot. And while it didn't penetrate all 12" of the flood swollen ash tree, there was a 2" pucker mark surrounding a nice half inch hole, and I couldn't dig the slug out with my knife.
So I tried another maxi hunter on the old ash tree, and sadly it didn't punch through the second time either, but once again I was able to call the shot, and it was a clean round hole that went in deep and turned the surrounding wood into pulp. Those little fellas hit hard!

I'm not tryin to brag on my shooting, cause its not like I was shooting very far or making tiny groups. I'm just trying to show what a great rifle this is. Its got the balance, and the accuracy to shoot it offhand and HIT what your aiming at EVERY time, and while it packs a heck of a punch, it only punches what your shooting at. Some good hearing protection is all you need to shoot it all day comfortably.
I can't recommend this rifle enough to someone looking to get started in blackpowder :D
 
As a first rifle, I can think of none finer. It's also more accurate to the Fur Trade era guns than the TC Hawkins. I have a GP myself. :)
 
questions

for most use, which barrel might be a better choice?

the 1 in 60 or the 1 in 32?

Sheesh there's even a 1 in 48 for the Trade riifle.

Stupid Lyman website doesn't give one a whole lot of information.

Teasing me, you are...
 
Personally, I recommend the 1-60".
This is the twist rate for shooting patch and ball loads. It is very accurate, and from what others have said, a .50 or .54 is quite capable of taking deer at moderate range with ball.
Shooting ball, is a heck of a lot cheaper since the ball itself is cheaper (buy 100 for the cost of 20 buffalo bullets) than conicals and you don't generally use as much powder. You also just have to patch it rather than messing with lube.
And like I said above, at least in my gun with the TC buffalo bullets its still accurate enough to kill deer out as far as I was shooting it and probably farther than that. So if you REALLY want to use those big hunks of lead on a deer you can with a slow twist barrel, you'll just have to do some experimenting to find out how far it will be accurate to.

The fast twist rate will shoot conicals and only conicals. Your stuck with buffalo bullets and sabots. A patch will simply shred coming out of this barrel and probably won't produce any kind of accuracy. Conicals/sabots are expensive from what I've seen. I suppose you could cast your own bullets, but if your buying them your going to pay. Sabots sound like they're a PITA to shoot too much cause you have the added challenge of cleaning plastic out of your barrel instead of just fouling which comes right out with hot water or butch's bore shine.

The 1-48" twist is supposed to be a compromise. And from what I have read, second hand only I don't have any personal experience....its just that. A compromise. It does shoot both but neither one very well. So going by that, and by my limited experimenting with my gun last weekend I would much prefer to get the 60" twist and be garaunteed to shoot ball accurately and have a good chance of shooting conicals decently.

And to throw another variable in for you, they do sell just barrels. So you can buy a GPR with a slow twist, and for another $175 or so, you can get that fast twist barrel to pop in around deer season and shoot those XTP's :D

Personally, I'm real happy just having the slow twist.
 
Thought I should add, changing the barrel is easy. Its a hooked breech set up. You remove the two keys, which simply slip out and then lift/rotate the barrel out of the stock. Lay the other back in, put the keys in and your ready to shoot :D
 
Midsouth Shooters Supply has the barrels for around $125ea if I remember correctly.
A 1-32 can still shoot roundballs, it's just that it probably won't so well accuracy wise. Velocity is another part of the equation as to what stabilizes and what doesn't. A short conical going very fast may stabilize ok even in a round ball slow twist barrel (1-60).
