I was out at the range today shooting a couple of my wheel guns, had a really good time.

I had an opportunity to enlighten a couple of other fellows on the line about barrel length and it's perceived effect on accuracy. One of the revolvers I was shooting was my S&W 66-5, which is a snub.

I was shooting my own reloads, using a long time, as well effective recipe of 140 gr. and 158 gr. XTP HP's, with a max charge of 296.

Initially, one of the guys on the line made a comment during a cease fire, that although that snub with those loads sounds impressive, but I bet it's about as accurate as sling shot at 100 yds.. He was obviously being sarcastic. So when we went green, I picked up the 66-5 and started shooting the target at 20 yds., which I was shooting off a sand bag rest. He was watching intently as I emptied the cylinder twice, producing a near single ragged hole in the bull. the groups was so consistent, that of the 12 rounds I fired, only 8 discernible holes were visible. Honestly, I didn't measure the group, but it was about an inch, and dead center of the bull.

As I was extracting the last cylinder of brass, he walked over and apologized for having under estimated the accuracy potential of both the 66-5 and full house 296, jacketed loads. I then went on to shoot back to back cylinders with similar groups, this time with some 110 gr. and 125 gr. XTP's, also loaded with 296.

The expression on his face was priceless, to say the least. But he did have the decency to walk over to me and apologize for his arrogant remark, and then complimented my shooting skills. As it turned out, he himself was a darn good shooter, as I discovered when I let him shoot a few cylinders of my full house loads using the M66 with a 20 oz. trigger, and my 4" Taurus 608. And rather than let a remark like that cast a dark cloud on my day, we ended up trading stories and interests, along with a friendly hand shake.

Later in my shooting session I shot at 50 yds with the same loads, and by golly I shot a really nice group at that distance also, not an inch, but dog gone nice, none the less. But today was one of my good days, something I've come to appreciate as my vision continues to degrade with age.

I have a 2 1/2" Ruger Alaskan in .480 Ruger. It is quite accurate and reasonably easy to shoot and quite packable. It weighs 42 oz unloaded and 50 oz with six 400gr cartridges.

Bought because I was always intrigued by the concept and justified it as a "backup" while bow hunting elk in bear country. Turned out it's a lot of fun to shoot. More than enough accuracy for it's intended.

First six shots off hand at 9 yards to get a feel for the gun and check POI of various loads.

Shot this target while chonographing loads. 385gr HP at 1,050 fps. Upper left benched at 25 yards while chonographing. Lower right (after moving windage right a bit) at 12 yards off hand.

Here's a link to a post on Jeff Ault's facebook page -- showing Jeff shooting the Alaskan at a 75 yd popper and his opinion of the Alaskan. Jeff was trained by Bob Munden and took over the business after Bob passed. I know Bob was one of a kind but Jeff is one of the best shot's I've ever seen and an excellent gunsmith in his own right.

I believe it was RC model that said it all depends on your eyes, some people are just good with shorter barrels because of their sight . I know m 3.75 inch barrel Ruger SBH is more accurate in my hands than my full 7.5 inch barrel one is.
 
I gotta get me one of those Alaskans. It is a serious handful of accuracy and power. Good shooting.
 
So long as the rifling starts the bullet spinning, longer length barrels will offer better velocity and sight radius, but not a whole lot more except balance and weight - and that can be important when it comes to unsupported hand held accuracy. :uhoh:

Then the combination of lighter weight and shorter sight radius comes into play, especially if you are shooting heavier bullets because, all other things being equal, it produce heavier recoil. You may then find a marked difference between short (less then 4 inches) and longer (6 inches or more) barrels in hand-held groups - most noticeable at longer distances.

All of this is one reason that bullseye target shooters - where maximum hand-held accuracy is everything - tend to shoot longer barrel lengths combined with moderate loads.

However if you are shooting from a rest - especially a machine rest - the accuracy difference between long and short barrels becomes much less, measured as is usually done, at 50 yards.
 
I had wanted a ruger alaskan til lipseys made that redhawk with the 2.75 inch barrel, if only they offered it in .45 colt, but i can Live with the .44 mag.
The Kodiak Backpacker! Yep I've had my eye on that one too. Looks like a nice version of the Redhawk if you dig short barreled guns.

And I do.
 
Maybe it’s just me or my fading eye sight, but I have S&W’s in 38 and 357 with barrels of 2, 3, 4, 5 and 6 inches. I can shoot more accurately with my 3” model 13 followed by the 4” model 19’s. The 5” and 6”ers have the least accuracy but I blame that on the all black sights.

Yep thats the one , Mama Bear said I can only get one more gun for 6 months , so Im gonna save every last penny for the kodiak redhawk. Would look great next to my 5.5 inch barrel redhawk.
 
You know, way back in the dark ages, I was a federal agent and we were required to carry American-made revolvers for duty. I carried either a S&W Model 66 or a Model 60, depending on how I felt that day. 2.5" on the 66, and 2" on the 60.

We had to qualify quarterly with those guns, which included drawing from a holster and firing at 25 yard targets. It is purely amazing how well you can do with practice, with a 2" barrel. I believe I only dropped a couple of points total, in 7 years of carry.

We were restricted to .38 Special loads, but they issued us the old Gov't (non-retail) 110 gr. JHPs, +P+ loads.

Never make fun of a guy with 2" protrusion. :)
 
I watched a feller at a CA Swat training school put on an demonstration about the accuracy of various guns.

He started with a 30-06 bolt action with scope and all the goodies. He put two rounds on a gong hanging on a cliff 200 yards away.

Then he did it with a Winchester lever action .32 special with iron sights. Then a Model 27 S&W .357 Magnum.

Then he pulls out a Model 10 2" .38 Special and did the same thing.

Bottom line, he obviously knew where to aim each gun to hit the target....

Hmmm? Ya s'pose I'm onto sumthin' here?

The gun will do it's part if the feller behind it does his.:cool:
