snub 357 mag velocity

Deja vu,

But just 1 example of the weight (125) considered by many to be the most effective 357mag? Their 158 357magnum load gave higher velocities then the 125DXP.

You might find at least some of the info you are looking for at < https://www.buffalobore.com/ >. Check out the technical articles and different loadings they offer, they say what firearms they use for testing and include snubs. As I reload all my center fire ammo I have never used theirs but they get good reviews especially if you are wanting full power ammo.

Hope this might help.


PS: I enjoy "Ballistics By The Inch" and you will never hear me criticize them. I am pretty sure they visit here, good job guys.
 
It's my carry ammo for an M&P 360 scandium frame in .38sp. I have checked it several times over the years with a chrono, and consistently get 1050fps out of my gun. It's a handful, but manageable.

To those interested the "Balistics by the Inch" website has a section under cylinder gaps where they compare several revolvers < http://www.ballisticsbytheinch.com/realgap.html > including a couple snub nose. I am thinking that is were you got the velocity reference you were mentioning.

Everyone has their opinions and mine is; I like the 158 grain bullets like the ones you are looking at from Buffalo Bore especially in a short barrel firearm. I load mine with straight 158 grain semi wad cutters and a fast powder. I am not sure how I feel about the hollow point part.
 
Hand loading I am sure you could exceed those numbers but that would exceed the SAMMI pressures firearms are designed to and I don't think that is a good idea. I don't buy center fire ammo but if I did Buffalo Bore would get serious consideration. I am also thinking they have testing equipment beyond my means.

I use 4.3 grains Bullseye which is right below +P in Hornaday's 7th edition manual for jacketed bullets. Jacketed bullets are supposed to have more friction in the forcing cone and barrel so pressure should be lower with a lead bullet but you are supposed to get an increase in velocity.
 
CorBon's DPX 125 is a "Lower Recoil" sub magnum load. These type of loads also get compared to 38+P and 9mm out of short barrel revolvers.

Kinda like comparing the acceleration of a new 300hp V6 Mustang to a new V8 426hp SS Camaro and declaring the Chevy the winner. Now if it were a full power V8 GT Mustang vs a V8 SS Camaro then the conclusion could be considered valid.

You're still complaining about what they tested.

They weren't comparing one load to another
They were comparing only the effects of different barrel lengths and types

They didn't "declare winners"
They simply gave results
 
Last time I chronographed factory .357 Magnum ammo through various revolvers, I used Federal American Eagle JSP. While I didn't think to write down the exact numbers, I was averaging ~1150 fps from my 2 1/2" S&W M66, ~1200 fps from my 3" S&W M13, ~1300 fps from my 4" S&W M28, and slightly under 1350 fps from my 5" S&W M27. While I didn't chrono as much of it, I got very similar number from Remington HTP 158 gr SJHP which is my chosen self-defense .357 Magnum loading. These Federal and Remington loadings are advertised at 1240 fps and 1235 fps respectively and while Federal does not specify a barrel length, Remington states a 4" vented test barrel for their advertised velocities.
 
Snyper,

You are correct in that ballisticsbytheinch are just reporting the ammo they tested and calling them deceptive is unfair on my part. What I don't agree with is when people use their T/C shortened barrel data to backup the 38+p vs 357 revolver discussion. Yes, the 357 looses quite a bit when the barrel is short but it still out classes any 38spl load, especially with the heavier 158gr bullets. Our fellow members who were kind enough to share their chronograph data are much appreciated.
