For 50 years I have heard of "For Rifle Only" 44-40 [and 32-20] ammo but I have never actually seen any. Nor have I seen the specs to see the difference.

NOT FOR PISTOLS
NOTE H.V. HEADSTAMPS
NOTE H.V. HEADSTAMPS
And the neutered High Velocity by Remington tha can be used in all revolvers etc.

Beginning back in 1903, and for about the next 40 years, higher velocity .44-40 cartridges were offered for both the '94 Marlin and '92 Winchester. Catalog velocity was almost 1,600 f.p.s. with a 200 gr. jacketed bullet. Pressure was reported to be around 22,000 p.s.i. and therefore were not safe to be used in the '73 Winchester.
Lately, I have been working with my '94 Marlin Cowboy Ltd. (24") replicating those vintage factory offerings. As I recall. 44-40 Willy had done some of this in the past.
The jacketed bullets I have used have been 1.)R-P 200 gr. .427", 2.)Winchester 200 gr. .426" 3.) Speer 200 gr. .429"
The groove diameter in my rifle is .428" and all of the bullets shot well even though both the R-P and Winchester were smaller than the groove diamater. Surprisingly, the smallest group was fired with the Winchester bullet that was .002" under groove diameter.
Using R-P cases, here are the loads I have tried:
20 / 2400 / 1,670 f.p.s.
21 / 4759 / 1,619 f.p.s. (Capacity load)
21 / H4227 / 1,610 f.p.s.
25 / XMP5744 / 1,630 f.p.s. (Capacity load)
All of these loads shot groups in the 1 1/2" range @ 50 yards.
The best group to date came with a slightly higher charge of H4227 under the Winchester bullet.
22 / H4227 /1,685 f.p.s. went into less than 1" for 5 shots @ 50 yards....but the powder had to be positioned to the back of the case to get that result/
I'ts been kind of neat stepping back in history and shooting these replication loads of days gone by.

Also, look back at the targets I posted and review target #181...right target head shots. 200gr Lasercast at 1,500fps @ 100 yards at barely +P loads....well below the +P+ 22,000psi SAAMI from yeasteryears HV factory loads. No leading!
