    Hey Old Coot, Yep, if it weren't a Sharps, that is what would have been first on the list. If you own a sharps, look at the barrel next to the receiver. If it does not have a tulip but has a Hartford collar, you can set it back but if the rear barrel flairs into the tulip, the forearm is not set up for it, you have a large hole. The wood and barrel aren't a match anymore.

    Ted, I have regretted almost every firearm I have ever sold! Just hold on to that rifle. There is a gentleman on here, John Taylor and (his place is in the North West, maybe close enough to you to drive) he relines barrels. I hear he is good and reliable. The cost may be about half the price of a new one. Those large cases you have for the 45-120 bring a good price even used. I don't know how many you have. They could offset a little of the Smithing cost and take some of the sting out of it.

    What about going the old way and fiting a tube into the cases from just beow the bullet and to the case head. These could be glued in, lightly pressed in place or installed and a channelure rolled to hold them in place. SOme of the modern plastics may make a long lasting sleeve. A section of .410 shotshell might press in snug and take alot of spce away. This would be like the 45-70 carbine load with the 405 grn bullet and 55 grns of powder. It might do just what you want

    That sounds like it could come out upon firing and lodge in the barrel.
    On every question of construction let us carry ourselves back to the time when the Constitution was adopted, recollect the spirit manifested in the debates, and instead of trying what meaning may be squeezed out of the text or invented against it, conform to the probable one in which it was passed.

    In my experience, the best case filler for reduced smokeless loads is foam backer rod.
    It is the foam coil sold in hardware stores to press into gaps around windows and door jambs.
    It is cheap, weighs nothing, comes in three or four diameters so fits snugly into the case and is easily cut to length.
    In the 45-120 start with about 40-45grs of 4198 and fill the space with backer rod to the base of your boolit.

    I have also worried about ringing chambers but I am shooting only lead with no crimp in reduced loads and my theory is that for a filler to advance toward the base of the boolit with enough energy to ring the chamber, the boolit would have to be pretty immobile for that split second before moving down the bore. I've never had any issues - knock on wood...

    I have never had an issue with a rung chamber either ... Don't want to either.

    Yes my 120 barrel has the Hartford ring on the breech end of the heavy oct barrel ... So setting it back should present no particular problem except for having to re d&t new forearm holes and moving the spring mount for the 74 action.

    Boolit head ... Great avatar bubba. Gotta gawk Everytime I see it. NICE!!!

    My main thrust now is putting together a barrel for the Encore. She will be a 45 Colt chamber and fairly tight to do spme smokeless patching for.

    This is beyond STUPID. I have a 450 3&1/2" Nitro Express. It's a HUGE bottle neck case and works just fine with light loads, 300 gr cast boolits and my coarse cornmeal filler. Don't screw up a nice rifle, just try what actually works for me.

    Has no one read the series of articles by Sherman Bell in DGJ about pressure testing with fillers and/or Wrights book "Shooting the British Double Rifle" and the loads pressure tested by Kynoch and Birmingham Proof House? Corn meal, Cream of Wheat, cork wads and other fillers of that type raised pressures the most, sometimes to dangerous levels. Dacron, Kapok, open cell foam and of all things cotton balls, either gave a pressure readings similar to or below normal loads. I don't recall Styrofoam peanuts being tried but would expect them similar to open cell foam. I don't believe chamber ringing an issue with any of the fillers Wright and Bell found pressure acceptable. It's a fact I haven't rung a chamber yet in 50 years of reloading and using fillers.

    I know for a fact corn meal WILL solidify into a solid plug and in a bottleneck case is dangerous. I didn't shoot any, thankfully, but when I pulled the bullets after 10-15 years of them being loaded I had to pick the corn meal out of the case. I don't know what would have happened had I fired any.

    I use corn meal in a 40/82 Winchester, works well.

    I have played with wheat bran and wheat germ as a filler in a bottle neck case. Both of these raise chamber pressure but wheat germ the least. Wheat germ works better in a bottle neck because it flows better and doesn't leave a ring of itself behind the shoulder.

    I did find that light loads of bulky shotgun powder with wheat bran caused high pressure in the neck area. I know this because the neck would expand into rust pits which doesn't happen with normal full pressure loads. This while the primer flattening indicates low pressure.

    Well, I don't load cast boolits and let them sit for 15 years. The Cuban style cornmeal is very coarse and works better (accuracy) than the fine American stuff. Dacron also works fine but it's a pain to make those balls, stuff in the case and pack down with a stick. Coarse cornmeal works fine thru a Lyman 55 measure.
