There are damn few revolvers capable of accuracy like this, but far few men who could prove what the gun is capable of.

Thanks all around. Thanks all the way back to Sam Colt. Thanks to Dick Casull, Freedom Arms, Ed & Doug Shilen, Jim Stroh, the Winchester folks, and Bruce Hodgdon, thanks to my High Power Rifle instructors and everyone I've rolled with in dirt. Cave Man thanks to those who don't know any other way.
The wind was rotten, like dynamiting rock zipped with fissures. A 10 o'clock wind whipped the range. I over-counted left windage----38-clicks, which put me into the gut zone of the cardboard deer. I do not have a ballistics program, let alone a wind gauge. All I have is INTUITION and RECKONING. The Model 70 7mm Rem Mag printed 4.2-inches @ 300 yds. The Stroh/Casull FA .44 Mag printed 4.9-inches at 300 yards. Just over a 1/2" difference. I would not want to pit the revolver against the rifle, and I would greatly prefer to kill my meat closer with either weapon. I expected in the chopping wind to string the .44 horizontal. Not because of any instability, rather due to the challenge of squeezing each shot into the same wind drift.
SIGHT DOPE---300 yards
Rifle 7mm Rem Mag----hold top of back, 8" left.
Revolver FA M83/Shilen .44 Mag, Leupold 2,5-8x34mm LER scope----starting from 100 yard ZERO: UP 64-clicks; Left 38-clicks.

Dan and CMH.... that is not a can on the Freedom Arms weth Shilen barrel. I asked Jim Stroh to use a Shilen blank, cut the taper .011" or so to match the M83 barrel, taper and ejector housing, then run it full 1.25" diameter to the muzzle. As Shilen offered a 1:16-inch twist, I thought I'd try it. If you don't try it, how do you know? Were I to rebarrel, I'd probably settle on the standard 1:20" twist S&W gurus settled on long before I was born. Experiments with Ruger during development of the .357 Maximum demonstrated a surprising tolerance of revolver bullets for varying twists. As you raise ballistic coefficient, a bullet's twist tolerance narrows----rapidly when you combine high BC with more weight.
JWP.... that revolver with iron sights would be like stage coach steering on a BMW. However, were this revolver to wear iron sights, nothing less than the old Bo-Mar would be appropriate.
Top photo: .44 cartridge with Sierra 240 JHC indicates Point of Aim. Over-doped the wind by about 8-inches.

Spectacular shooting as always David. I appreciate you sharing your range photos and encourage others to do the same. Theory and internet discussion is for naught unless we apply it. And your 44 seems quite happy with that 1:16 tube. Ed Shilen has shipped dozens of barrels to Arlington, VA since the 1970's and we've never felt the need to send one back. Their quality, and consistency for that matter, are first rate. -Lee www.singleactions.com"Building carpal tunnel one round at a time," |

Fowler.... tried for years to rate revolvers by accuracy at 100 yards. Since each revolver is an individual, the task made me ready for a straight jacket. So I tried to average by my experience with CORRECT EXAMPLES of production revolvers. A proper S&W M-29 prints in the 2-inch zone. A proper Ruger Super Blackhawk possibly a half-inch more. A proper Dan Wesson M44 .44 or M40 .357 Maximum prints sub-2-inch. A Freedom Arms M83 .44 prints sub-2-inch.
The "average" very good Ruger or S&W groups sub-5-inch at 100 yards.
Anyone after revolver accuracy starts with excellent ammunition. A crap revolver fed excellent ammunition shoots crap groups. So these things must be learned.
Now, I've got to eat venison.

Great shooting and great pics too.
Your everyday groups in bad wind rival my best days under perfect conditions and numerous spotter rounds....that's some stone cold shooting. I am just happey to hit the steel swinger beyond 200yds.
Thanks for sharing that.
I'm gonna go practice more...
