Didn't haul my chronograph along - sorry 'bout that. But I did shoot the factory loaded 405 gr Remington into a row of water-filled one-gallon milk jugs at about 20 yards. Remington advertises the velocity at a sedate 1330 fps.
Bullet was recovered from the 8th jug. Recovered weight is 397 grains, measured .530" at widest diameter. This bullet barely expanded, and penetrated deeper than either the 350 Swift or the 350 Hornady in my limited testing. They however, were launched at over 2000 fps and expanded quite a bit more.
Regards, Guy

try loading that 405 remington bullet over a 215 federal primer and 50 grains of H-4895, it makes it much more effective

Oh yeah - I shot 'em for years over a stout charge of Reloader 7... Lots of fun! Effective on mule deer too!
Here are some photos I shot of the 350 gr Swift A-Frame and 350 gr Hornady, loaded with 50 gr H4198. The Swift was doing about 2050, the Hornady about 2090.
Neither of them penetrated quite as far as the much milder Rem factory load, but both had pretty impressive expansion.

That 405gr Rem is one of the best. In my tests, and hunting experience, it's far tougher than the 350gr Hornady (I can't speak for the 350gr Swift as I've never used it). Sad that Remington no longer makes it. But I've hoarded a supply! At 2100+fps from my Marlin with a 22" tube it will flatten any black bear in it's tracks. They never even wiggle! That's with Rem nickel brass, WLRM primers and a healthy dose of RL-7 or AA2015. CUP is just under 44,000. That's also a good load for moose out to 300 yds. I don't know about water jugs...  It also shoots MOA consistently.

I see in the latest Midway circular that the Remington .458 405 grain bullet is still available as a reloading component at $28.99 per hundred. Is the loaded ammo discontinued? I really like the bullet. With Reminton brass, CCI standard primers and 51.5 gr. IMR 3031 I get a chronoed 1810 fps. Very good accuracy. Survey of game harvested=dead as a door nail!

CUP is just under 44,000. That's also a good load for moose out to 300 yds.
44,000 CUP is equivalent to 48,802 KPSI.I would like to know whom recommends this load as the "accepted" operating pressure of the Marlin 1895 action in 45-70 is 40,000 CUP/42,740 KPSI.
Stretching it some are we not?Each and everyone of us has the option to ignore the industry standard but those that do,run the risk of shortening the life of there firearm.
I would like to see where you found out the Marlin 1895 action in 45-70 is acceptable at 44,000 CUP as an operating pressure?

The "K" connotes one thousand so you should either write this as "48,802 PSI" or "48.802 KPSI".
I agree it is not wise to run the Marlin 1895 45-70 at 44,000 CUP and even 44,000 PSI would be pushing it.

Strongly agree w/"Logcutter" and Jackfish - no need to push the Marlin real hard. It kills quite nicely at rather mild pressure and velocity. If I wanted a .458 Win mag or a .460 Weatherby, I'd buy one!

thats the load I pointed out before,its a mid range pressure load that should give about 1600fps and good accuracy, keep in mind with a 45 cal 405 grain load you don,t need to stress the gun to get good results on game, pushing the pressure up results in more recoil and less accuracy and darn little else is gained with the increased velocity except more stress on the gun, 1600-1800fps, with the powders like IMR 4895,IMR 3031,WW748,IMR 4198,RL7, IMR 4064, is where the gun and that bullet performs best, theres no sence in pushing those bullets faster it won,t kill much better and it will thump your shoulder harder for nothing.
the guys are correct, if your looking for more than about 1800fps from a 405 grain remington you probably should have bought a 458 win, yeah you can safely exceed 1800fps some in a marlin 45/70 but nothings really gained in lethality on game

As I recall, the load I used on my mulie doe was only 45 grains of Reloader 7 under the Rem 405 gr bullet, and produced about 1650 fps from the stubby Guide Gun. It whacked that deer real hard!

I've killed many plastic jugs with factory 45/70 ammo,afew deer and black bear ...always worked.they would poke out of my Marlins barrel @ 1150 FPS. slow but very effective.

Anyway,thanks for straightening me out as that was intolerable.The point being,if anyone got it,40,000 CUP is set as the accepted standard for the modern 45-70 as a safe operating pressure and one should not knowingly and willingly exceed that pressure to try and make the 45-70 a .458 Win Mag.It does just fine at the pressures it handles with ease.
