1874 Sharps Pedersoli help..

I took my Sharps to the range and I can't seem to get it to group. The rifle shoots way to the right and I had to crank the rear sight far to the left to compensate.

Thoughts?





The upper left is the Sharps..

These have a fast twist. They are happier with heavier bullets. The "cowboy" cartridges don't have enough velocity to stabilize the bullet. You might have to go with a gas check (or jacketed) bullet to get enough out of a 400gr bullet.
The bore in the Pedersoli is .458. .459 lead bullets will badly foul the barrel after a few shots.
I've had good luck with the 500gr Montana Precision bullets.

Would that also explain the rifle shooting far to the right? The three shots far to the right were the first shots of the day.

Your Sharps covered up the M14 just right to where I thought you had somehow scout mounted the Sharps with something strangely similar to an M14 mount... I was about to give you an earfull

It's bad enough when people mount up their leverguns. I took the the mount off both Rio Grandes right away (you know, the one I'm about to get rid of )

Not sure how much good a scope does for such a rainbow trajectory anyways...

Very nice rifle though, I'd love to try one

First check to see if your front site is centered with your bore. Then get a small level and put it on the topflat of the barrel. Then put the level on the side of your rear sight shaft. If you use 2 squares instead of levels it's more accurate. What you are checking for is seeing if the rear sight might be canted one either to the left or right of the front. If it is you can put a shim under one side or the other of the rear sight base and square it up.

This happened to me when I put a rear sight similar to yours on my pedersoli and it corrected the problem. If you are shooting factory ammo, try different loads and stay away from Hornady lever evolution. It has shorter brass made for lever action rifles if you plan to reload the brass.

Like Stoky say's they are happiest with heavy slow bullets.

To get the best info on shooting this type of rifle go to the -shilosharps- forum or the - castboolits- forum. These are great sites with very friendly and knowledgeable people.

Thanks from Gus Fisher

I am told that LEVERevolution brass is only good for reloading LEVERevolution bullets because of the short length, at least with .45-70. Probably everything else too though.

I have the same rifle, but fortunatley not the same problem. Agree with speerchucker that frist place to look is to see if the front sight might need to be drifted. Then check to see if the long range tang sight is square with everything else. Hopefully this will solve the windage issue.

As for grouping you'll just have to find a load the rifle likes. Strangely, mine likes the 300gr jacketed flat point Remington factory load the best.

Buckeye - I thought about this a little further last night. It has been quite awhile since i mounted sights to my rifle. I changed out the front sight with an interchangeable post setup that includes a spirit level. It looks like you might have something similar.

When it was time to mount the tang sight to the rifle, I placed the rifle in a vise and got it level across using to flat on the top of the barrel. Across the garage i hung a heavy washer from a string. Then I mounted the tang sight and compared it to the string. To get the rear tang sight vertical required a little filing on the base of the sight where it meets the tang. Mine came slightly concave to allow for filing to get level.

You probably did all of this - but if not, might give it a try. The more accurate the level you have the better. As speerchucker says' squares would be better.

Since you were on a bench with a mechanical rest, you folded the sight down and compared the target through the bore and the sights?

Here's a few more thoughts. These steps have worked for me and may or may not work for you.

Feel free to ignore all of the following,

Once you have determined that tang sight is square with the front sight your windage problem should easily be adjusted for. All the info I am about to repeat I learned from the two forums I mentioned earlier.

If you have shot any jacketed bullets prior to shooting lead, you must removed all traces of copper fouling. Your barrel will lead up if not removed, and your groups will not get any better.

Most leading is caused by the lead bullet being too small diameter. A smaller diameter bullet lets the burning powder slip past the projectile and melt the lead, which bonds to the barrel.

The next common cause of leading is the bullet lube that is applied to the lube grooves.What is applied on factory loads, may or may not work in everone's rifle. Most BPCR shooters load their own and apply one of the many recipes found on the above mentioned forums.

Lead bullets do just what the name implies. *LEAD*. This is easily controlled with proper cleaning. I use a bristol brush wrapped with bronze wool. Enough to get a very tight seal and forcefully push through the bore, after wetting the bore and letting it sit awhile with with Kroil. After the mutiple scrubs with the bronze wool, I then use very tight patches to do my regular cleaning.

My groups closed CONSIDERABLY after doing this a few times. I have been shooting my Pedersoli's about 3 years now and cast my own lead bullets. My 32 inch barrel will shoot Blackhills factory ammo with very good groups, while my 30inch is so-so. I was advised to find out what works in my rifle and did.I could go on for another 2 pages but I won't.

Please check out the 'Castboolits' forum and the 'Shilorifle' forums. They are full of great info and people.

DISCLAIMER: This info has worked for me and I am only relating my experience. I am in no way an expert and telling others what to do. You have to do the research and find out what works- IN YOUR RIFLE-

Good luck in your endeavors..... speer [not spear] chucker

Stoky brings a critical point to light and one I forgot to mention. IIRC, I leveled the rifle and then aligned the string with the center of the bore (looking through the bore). This may take a few iterations. From there, you can begin the sight alignment process. If you bump the rifle at any point, you should check level and alignment with the string again. As Speerchucker notes this should get you close windage wise and on the paper. I was in pretty good shape at 100 if memory serves.

Never finished developing a good load for it. Somehow got involved with an M1a and learning to shoot service rifle.

Good luck.

I checked the sights several times and they are straight and true. This rifle only has about 60 rounds through it and it has been cleaned after each outing.

I think I am going to try 500 grain ammo and see what happens.

I see that drcook from the shiloh forums offered to help. Take him up on it.There are plenty of good shooters/people that shoot these big ole single shots. There are usually monthly shoots in just about every location in the country. If you are willing to learn , they will show you the way. Once you get your rifle shooting good groups, it becomes an addiction.
Good Luck to you

Thanks from IC2(SS)19Z50C5
