Ronnie and Lee.... you have math. I have a bottle cap abacus. I measure revolver groups to 1/10” (0.1”). There is no reason to measure a reliever group in hundredths----let alone 1/1000----inch. Hell, there’s no reason to measure the best IHMSA Unlimited pistol, nor the best hunting single shot, tighter than 0.1-inch. Let’s look at a group of five or six revolver rounds which hit the 5-foot banana rock @ 600 yards. a 60” group @ 600 yards reduces straight to 10” @ 100 yards. Which reduces straight to 2.5” @ 25 yards. This exercise presumes there is no cone of dispersion (accuracy degradation) as distance increases. The Blackhawk .357 Maximum with 10-1/2” barrel has a target sight .100” wide. Depending on the shooter’s anatomy, from the Isoceles standing position, the front sight is 8” wide @ 100 yards. Same sight picture widens the 1/10” sight to 48”, or 4 feet, @ 600 yards. An estimate, of course, as any variation in EYE RELIEF changes width of front sight on target. Long eye relief narrows front sight (subvention). Short eye relief widens front sight. This seance in Raton, New Mexico was attended and witnessed by reputable shooters. A target six football fields yonder the muzzle introduces atmospheric fuzz a closer target cannot imagine. It proves FOLLOW THROUGH an absolute necessity. the collective consistency if these shooters throws down a gauntlet answerable in witnessed performance only. To put it Country Simple, this squad of hombres can shoot. If the revolver can’t do it, the bullet can’t do it. If the bullet can’t do it, the shooter can’t do it. David Bradshaw (To put it Country Simple, this squad of hombres can shoot.) Yes sir, i can attest to that. Not to Mention that if that rock is 5 or so foot long, then being the banana shape that it is, that means it is somewher between a foot and a foot and a half tall. So yes sir i was impressed. I love shooting long distance. This year myself and a few otheres are going after the white buffalo with 500 Maximums and 525s. It is almost twice that distance. It is a a full sized silhouette of a Buffalo.Supposed to be about 11 something. I wanna here that Mammy gongggggg. Should be fun. R

Very nice gun you picked up & good advice, it will save you a few primers working up a load if you're using the Bradshaw/Martin bullet. Send some target photo's! Dick Hey Dick How far away is the white Buffalo in Raton? R

First off, I'm a Ruger DA guy (shooter and collector of the Security Six series and newer). BUT, I am not so dumb as to not buy something special when the opportunity knocks. In the spring of 2022 I had a customer bring a dozen Rugers to my shop (I'm an FFL who does general repairs and Cerakoting) to have me sell for him. One was a basically NIB 7 1/2" Maximum, he said he had only shot one cylinder of amoo that a friend gave him and didn't shoot it any more so wanted to sell it (he really didn't know what he had). I immediately said to myself, "this isn't leaving here, I'm buying it". With my consignment commissions for the other guns, I got it at a great price.
I called my friend - contender - and filled him in. He told me that he would send me (I bought them) some of the Bradshaw/Martin bullets that he had cast and to use 18.5 grs of IMR 4227. I found and got some Starline .357 Max brass at a gun show (OGCA July 2022) and loaded them up. Oct 2022 was down at contenders place and got to shoot them. What a great combination. ACCURATE and fun to shoot, I had a great big grin when I was done shooting it. This gun will not leave my gun safe until I die and the kids sell it.

Ronnie, I believe 1200 yds but I easily could be wrong. Glenn Swaggart would know right down to the inch! Me & Ken O'Neill took a few shots at it a few years back with one of Bob Bakers round butt guns, can't remember the caliber but I do know it was a fair piece out there. Looked like a Texas grasshopper.

Everyone extolls the long range virtues of the 357 Maximum, and justly so, but I am impressed with it's close range abilities.
Where I hunt here in the foothills of NC, shots are not long. I hunt funnels in travel corridors, which usually meens shots are close. Very close. 50yds is a long shot. Less than 20 is more normal. Sometimes it is just a few feet.
The Maximum loaded with any of the three main bullets I use from MP molds(359-640,358429,or 360-180 Carbine) on a case full of 4227 seem to hit as well as a 30-30. You can actually see the shock wave radiate out from the hit and they are down within a few yards if not right there.

Loaded up 50 rounds with the Bradshaw-Martin bullet (got them from Sixshot a while back) and 18.5 grains of 4227 per the suggestions.

Is the bevel on your meplat caused by the seating plug? If so, I’d try a SWC seating plug, or an ogive seater. David Bradshaw

With such a long bullet and tight neck tension (thus the deformed nose) I am not worried about bullet pull

Order some for all your revolver dies at the same time. If not, it costs more for them to mail it to you than a plug costs.

Wayne, I've used the same 3 bullets you mention, plus the Bradshaw/Martin on deer or antelope but I haven't seen the shock waves you mention. Mine have been a little bit farther out but I still say the 357 Maximum or the 41 magnum is my #1 favorite revolver..... I know that's 2 revolvers but I learned my math from Tyrone Dick

bamagreg.... those bullets won’t pull. I use minimal roll crimp. As you note, neck tension holds bullet. Just as important, the deep seat provides uniform holdback during critical phase of ignition.
Only compariative targeting @ 100 yards can say whether a slight meplat distortion will degrade accuracy. Sure is ugly!
As Trapr advises, a flat seater plug will do the trick, and doesn’t care how wide the meplat is. Just make sure the bullet is on-axis (not tilted) to start seating. David Bradshaw

I know that's 2 revolvers but I learned my math from Tyrone Dick I believe it's the close range and high velocity that creates the effect. That and 12bhn alloy with the large hp pins. The skin and fat just ripples around the impact. I don't trust the penta pin yet on game.
