David,
Truly fascinating. Looks like I would take the 1/16.

David, Truly fascinating. Looks like I would take the 1/16. ***** Jayhawker.... thanks for the kind words. Fortunately, the low ballistic coefficient of most revolver and pistol bullets renders them less sensitive to twist rates that slippery rifle projectiles. To digress for a moment: even more fortunate for the revolver shooter, slight chamber-to-bore misalignment exerts only a minor affect on accuracy. This observation comes from the 100 yard to 200 meter Firing Line and is not subject to argument based on undemonstrated theory. And I attach serious caveats: namely, unforgiving elements of a revolver’s DIMENTIONAL ORCHESTRA, without which tournament accuracy doesn’t happen. After each shooting session of SRM prototypes on the Ruger estate in Croydon, New Hampshire, Bill, Jr., would take the revolvers back to Southport, Connecticut, where all Ruger single actions were made and assembled until some time in 1992. As all ammunition was experimental----from Remington’s lab to my handloads----with Rocks & Dynamite thrown in, folks in Southport would strip and examine the revolvers. The SRM’s would then be reassembled, probably test fired, then carried north again for more lead slinging. While volume of fire was necessary to discern revolver behavior, my preference was to simultaneously target, with most of it @ 100 yards. I suggested 100 meters; Bill, Jr., preferred yards, so most of it was 100 yards, with occasional targets at 100 meters, 200 yards, and 200 meters. Because of the lay of the land on the sidehill behind Bill and Bill, Jr.’s houses, 150 meters/164 yards (IHMSA turkey distance) was not included. Fine with me, since the asymmetrical turkey is the most eye-fatiguing target in silhouette, and range sessions typically stretched hours. To ease the eye strain factor, Bill, Jr., drill & tapped SRM-2 for a Leupold 4x28mm Extended Eye Relief scope, in Leupold Dual Dovetail mount. This led to the next step: Bill, Jr., had SRM-2 fit with 10 barrels, twists ranging from 1:10 to 1::60. The twist experiment should have included my handloads with Hornady and Sierra .358 200 grain rifle bullets. SAAMI protocols insisted on results from collaborating ammo maker, Remington. My guess, we would have settled on 1:14”. As it was, 1:16” handled .358 200 grain round nose. So did 1:14”, and 1:14” grouped the Hornady .358 200 Spire Point @ 200 meters, which 1;16” failed to do. But, a 200 grain Spire Point is too long for the Maximum’s Total Loaded Cylinder Length 2.010"----cylinder, rear face to front face 1.950” + .060” rim thickness = 2.010”. Bill, Jr., proposed we experiment with a case length of 1.660”. I resisted, as it would necessitate a long frame, with thinning pf the bottom strap forward of trigger guard. Neith Bill, Sr., nor Bill, Jr., shared my concern, but both agreed to continue with the present SRM. To conjure Bill Ruger and Bill, Jr., today, with a snifter of cognac in front of Old Man’s tall fireplace ablaze, I would hand them that first production revolver, with a handful of our powder coated Bradshaw-Martin 194 SWC Gas Check, deep seated over 18.5/H4227, and say, “Tomorrow we shoot!” David Bradshaw |

David, sorry for the delay in responding. I've been gone all last week while attending the SHOT Show.
I have heard of the one & only Hawkeye in .357 Max, and would LOVE to have it in my collection!
I did have a polite discussion with Jason at SHOT about the revival of the Maxi revolver. I don't think it'll happen anytime soon, as Ruger has several other projects it wants to invest in. But,, never say never,, as it has "potential" to be chambered in a few other calibers that need the longer chambers a Maxi design has.

Lee & David, thank you for the detailed information. I find it fascinating.
David, your memory, even refreshed with notes of the era blows me away.
Have you been diagnosed with Hyperthymesia?
noun. hy·per·thy·me·sia : the uncommon ability that allows a person to spontaneously recall with great accuracy and detail a vast number of personal events or experiences and their associated dates : highly superior autobiographical memory.

Have you been diagnosed with Hyperthymesia? noun. hy·per·thy·me·sia : the uncommon ability that allows a person to spontaneously recall with great accuracy and detail a vast number of personal events or experiences and their associated dates : highly superior autobiographical memory. ***** WARDOG.... appreciate your kind words. And thank you for adding a word to my meger vocabulary: hyperthymesia. Parents reading to their children and children reading on their own fertilize learning. We can’t forget what we don't remember. A cousin of my grandmother Bradshaw told me, forty years ago, from the age of five she preferred to hang around adults, absorb oral history. She developed or was born with a photographic memory for people, places, events, and the stories elders. Like my grandmother, she was born to livestock and horses and never made the transition to driving an automobile. She became a genealogist of the area, sought by persons wanting to know their own family history. I bear a fraction of her interest and none of her talent. Glee Kelly noted some colorful characters in the family. One, a Capt. Wright, went to church one Sunday. The minister wasn’t long into his sermon when he turned to call out Capt. Wright to vilify him before the congregation for shooting a bear on Sunday. Hearing enough, Capt. Wright rose from his pew, drew a pistol from his belt, pistol at preacher “Desist, vain person!” Whereupon Capt. Wright marches minister and congregation out of the church, and bolting the door. In High Power riflery, we kept match notes, rifles, wind, light, etc. Later on, when I fell into silhouette, the practice resumed. When spotting or coaching, I encouraged the shooter to conditions and sight dope, which are bound to inform critical moves down the road. Had we not fed so many targets into the fireplace, my memory of the .357 Maximum would be better. David Bradshaw |
