40-82 crossno print request

Does anyone have an electronic simple copy of a 40-82 crossno reamer print??

I need basic dimensions to confirm it will clean up a specific chamber.

If anyone has the 40-82 win as well, id like to compare.

Mike

Ballards may be weaker,
but they sure are neater!

Why not contact Dave and see if he can email you the dimensions? You can get his contact info here:

Dave will usually give freely with his time if you call around 4:30 p.m. or so his time, as he's winding down then and answers phone calls.

If you call Manson Reamers, they can email you a copy of the 40-82.  I just got one a couple of weeks ago. Bob

Someone told me that the Crossno 40-82 is pretty much the same as the 40-65 Ballard Everlasting. If you have acess to those dimensions you will pretty much have the Crossno 40-82. I have both Ballard and the 40-82 Win drawing if you still need them.

A friend of mine has a 40-82 Crossno that was done by Dave to clean up a poorly done 40-65 chamber. Think of a 40/65 on steroids. It is a straight taper case 2.40" long with a .600" long straight neck. I don't know the neck diameter but I know it cleaned up a 40/65 chamber that was off center.

If Dave had just called it a 40/65 Ballard it would have never been as controversial as it has been. The dimensions are very close.

By NRA rules in black powder cartridge matches, cartridges must have a historical background of being chambered in firearms used in the United States prior to 1895 I think it is. Early on some cartridges such as the 40/70 Gov't were accepted which have no basis in history. This caused some controversy. The 40-82 Crossno was considered by some a new development with no historical basis. As I said, if he had just called it a 40/65 Ballard everlasting then everyone could compare it to an original and see that it was within a few thousandths of an inch all over and a very close match.

If the end-user goes with the 40-82 Crossno he can simply call it the 40/65 Ballard Everlasting and no controversy. Life is good.

This is the drill.
The GOOD MAN that John Taylor is, has agreed to rebore a swede 8x58 barrel at 30 inch to 40 cal, or at least take a shot at it.
The idea is to reuse for hunting purposes, several 8x58RD barrels that are not worthy of keeping.

I like the petite feel, balance, etc of the Swede roller in forester form.
I have a "GOOD" number of them, most all have exceptional case color, retaining 90% bluing on all but a few.
Tight, clean, just worn bores or having some scattered pitting. I have some that are pristine like unfired, those will stay as is.

My intent is to with or without a minor setback, rechamber to 40-82 win or crossno, to clean up the chamber following a rebore.
Shorten the barrel 3 inch, adapt a proper sight or relocate the current field worthy ramp front as is in several. Some have the military ladder sight calibrated to 2500 yards. Ill leave the sight. It should make a solid 28 inch 40 cal thumper, may not win at the bench rest, may foul a bit, but deer and animals dont allow a volley of 10. Its a one shot deal. I need precision, not accuracy, in a clean barrel.

Im sure that with a 350 in it, recoil will be substantial. Will it be 7MM mag substantial, I doubt it!

Thats the plan, Stan! It may not fly, JT is worried minutely about the barrel material and a good finish. Worst case is, I have a new tomato stake or a liner donor barrel for him to rework later.

I appreciate all the responses. I was able to procure a 40-82 win dimension so I have the needed numbers to overlay and ensure a clean chamber, as least in the "white papers". Everything may change when engineering becomes installation.

Mike

Think you will be pleasantly surprised how light the recoil will be with that 350gr bullet. I shoot a 412gr bullet with 65gr of powder in my 40cal and don't find it bad, at all. And, I'm a recoil pussy.
