My good friend just recieved his Sharps Quigley,he loaded 95grs.ffg,535gr lyman bullet.First trip t range they keyhole any help or comment ?
 
There's not enough information in your original post. The quick, easy answer is that the twist rate might not be fast enough for such a long bullet, but BPCR rifles have their own set of circumstances. There are a lot of variables involved and a one-line question doesn't tell us what we need to be helpful.

What's his barrel twist? What brand of powder is he using? What dies is he using? How is he loading the cartridge? Does he use a wad or coookie? Did he cast the bullet himself or buy it somewhere? What's the true diameter of the bullet? Is he sizing? Did he slug the barrel to learn about his land/groove diameters? All these things are important with a BPCR.
 
"ffg" means he was using black powder in his.....uh.....'black powder' cartridge rifle.
The keyholing indicates the bullet is not big enough for the bore. It is not engaging the rifling. I would think the company that made the rifle could provide reccomended bullet sizes for the barrel.
 
"ffg" means he was using black powder in his.....uh.....'black powder' cartridge rifle.

I think by brand, PawPaw meant swiss, goex, something else. Could have a bearing on performance.

I also agree with PawPaw that it could be way more than just bullet diameter. Rifling twist rate versus bullet weight/length can definitely be a contributor to keyholing, even if the bullet diameter is perfect. Definitely do as Rifleman suggests and check manufacturer recommendations.

I know that ffg is black, but I was asking about brand. I know that in my Sharps I had problems with 500 grain bullets until I started using Hodgdon Triple Seven with a grease cookie under the bullet. There are lots of things that might cause that bullet to keyhole, including bullet alloy. There are lots of questions you have to ask when you're having problems with a BPCR.
 
I agree with the recommendations that everyone else has suggested, especially that your buddy should slug the barrel. Every other fix is meaningless if that bullet is rattling around the bore.
 
95 grns. of powder in a case designed for 110? If he's not using a filler he's asking for trouble.
 
Yes it does but you cant get 110 grains of FF in a 110 case. 45-70 means 70 grians of BP too but you cant get more than 63 to 65 grains in a new case with FFF.
 
Gentlemen, remember, when the 70, 110, 120 designations were made when the cases were baloon head and the brass was MUCH thinner throughout the case. These old cases held much more powder than modern cases designed to use smokless and much higher pressures.
I can only get about 60 grains of compressed FFG black in a .45-70 Government case of any make.
That is my understanding of 1880's era brass, someone correct me if I am wrong.

That's my understanding as well. Those old balloon-style cases held more powder than the current production.

On another note, it looks like jms was a drive-by poster. We haven't heard from him since the original posting.

You should be able to get 65 in them without a compression die and still seat a 405 grain bullet. You can get 70 with compression and use a 500 grain bullet.
 
Where you getting your 45-70 case's, and just how much compression are you talking about? I have been shooting BPCR since 1980 and I can get no such loads in my guns, nor can any of the folks I shoot with.

Sharps Rifle Co. got it right the first time..and it looks like thry were alot smarter than us "enlightened" folk. The never stamped their arms .45-70, or .44-90. Instead they gave the length of case...45-2.1 for what we call .45-70
Thus they avoided all the guessing and questioning we see on this post.
 
I am well versed in compassion dies, If you look in my reloading room you will probably find 15 or 20 of them, I for the life of me cant figure why you would want that much compression. We have found that if you start cracking the powder you are basically making a new granulation this is not conclusive to accuracy.
 
Because I wanted to shoot rounds with original charges and bullet weights. Weren't too shabby either.
