Mercury recoil suppressor

^^ Yeah, those 458whims are way lighter loads, really nothing in comapre to a 3 1/2" goose shell at two ounces.

It's not really comparable.

What loads exactly are we talking about? I'm aware that the 458WM can go from what I deem stout to pretty obnoxious, but I'm not familiar with 3.5" 2 oz goose loads. What kind of recoil energy are we talking about (load and gun weight)?

There's some recoil tables and calculators online. Just look at the tables (e.g. Chuckhawks) for rifle/shotgun ammo...

I don't have a recoil "tester" and all calculations usually don't consider fit of gun for the shooter, or shooting position,... which can be detrimental for perceived recoil.

e.g.

Cartridge (Wb@MV)

Rifle/Gun Weight (lbs)

Recoil energy (ft. lbs)

.458 Win. Mag. (400 at 2050)

9.0

41.7

10 gauge, 3.5" (2 1/4 at 1210)

10.5

62.9

Thanks for that, I didn't realize the 10 had that much jam. I will say though, IMHO, that Chuckhawks recoil tables are sometimes a bit "off" in the sense that he'll thumb the scale by using a fatty for a rifle, while watering down the load. The 458WM example above is a perfect example, at least the load is. That load is possible in a 45-70 lever gun. A 500grn at 1800 fps out of a 8.5 lb 458WM rifle makes 58 ft lbs.

458 Win Mag example - from a November 1976 W-W Reloading pamphlet - 510 grain RN bullet at 2065 fps - page 61 - that probably gets yer attention!! Page 50 has notice that velocity is from 24" barrel, but does not give anything more about the test firearm - weight, twist rate, etc. I had some 510 grain W-W soft point Round Nose until recently - I think they ended up with a CGN guy in the Yukon who probably has a suitable use for them.

The pamphlet shows that load with 75 grains 748 powder making 41,000 CUP pressure - so I think it could go up a bit - but not many of us could take that!!

I agree. It only has exemplary meaning, I guess.

Haven't shot a 10 ga. with that kind of load but a 12ga Super Nova pump at around 8 lbs (unloaded) with Winchester DoubleX 3-1/2", 2 ounce @ 1300. Angling the gun up at a flock of incoming birds. Not gonna do that anymore,...

I load my 26" 458wm 400gr to 2400fps and 500gr to 2180fps. It weighs prolly 10lbs ive never weighed it
My 10ga bps synthetic stalker is i think 9.5lbs if I remember correctly. Its not bad at all with goose loads and even 2.25oz turkey loads. 18 pellet 00buck wakes it up.
My synthetic mossberg 535 with 22" barrel and 3.5" 2.25oz loads is just nasty. Ill take my 458wm loaded with rhino stoppers over the mossberg and turkey loads anyway


400gr at 2050fps is what id load if someone wanted to start to try a big bore.

I was gonna say 400gr at 2050fps is quite slow, factory ammo with 500gr are usually around 2150fps.
I load my 350gn at 2550fps and 400fr around 2300fps
