Anyone know anything about this Remington 45-70 405gr SP full power load? I bought a couple boxes of it and it differs from previous boxes of Remington Core Lokt 45-70 405gr in that it says "Full Power Load" on it and something like "for use in modern rifles only". I don't have a pic of it right now but I'm wondering if it's just the same old Remington 405gr in a new lawyer safety box or if it's a hotter load, because the old 45-70 Remington i've fired is definitely no where near a full power load. I've found nothing on the internet about it. I plan to chrono it next time I take the 45-70 out but that may not be for a while.
 
The laws of the land in Canada and USA, limit the maximum loads for 45-70 cartridges. With 105 grain bullets, velocity is supposed to be about 1450 fps. This is considered safe for the Springfield Trap door, in good condition.
I have some antique Winchester 45-70 cartridges with 405 grain bullet, some of the first ever made. I also have an 1884 Springfield Trapdoor and I recently fired one of the antique cartridges in it. The velocity was just about exactly what it was supposed to be, at about 1430 fps.
 
45-70 been around a LONG time and there's still a lot of older rifles out there that would have a bad day shooting some of the modern 'smokeless' powder ammo. Original 45-70 cartridges used black powder.
The original Remington 405gr ammo was good for 'all rifles' as the pressures generated were lower than other modern ammo. The stuff you have is good for modern rifles only and would be comparable to most other modern 45-70 cartridges available today. Well, maybe not Buffalo Bore:cool:
 
Here's a Remington 45 caliber 405gr FN bullet recovered from a Bull Moose I shot with my 45-70 Marlin. Muzzle speed was 1850 fps and range was about 75 meters so impact speed was about 1600 fps.

A rear quartering shot as it looked back that broke the close shoulder, severed the spinal chord and lodged in its neck - dropped DRT. Total penetration was only about 18". Hornady 45 caliber 350gr RN shown for comparison.

Point is there's no +P 'greenbox' 405 gr 45-70 ammo on the shelves.
Remington makes the same ole stuff with the garden hose trajectory for the trapdoors and that's it.
Buffalo Bore makes a suped up 405 grain 45-70 load but it's almost $100 a box.
Get a Lee Hand Press ($59.95), some cases, bulk bullets, primers, H4198 powder and < $200 worth of supplies and using data from bonafide online sites make your own.

Trajectories for the 405gr starting out at 1330 fps compared to 1850 fps. Sharp drop off beyond 150 yards for the standard load, and beyond 200 yards for the higher speed load.

No problem on targets beyond those ranges using a rangefinder and a scope with a ballistic reticle. ;)

We're leery of remlins on sale.
We don't buy them sight unseen.
We took a chance on one from cabelas a couple of years ago and got one with crappy shadow checkering that had no depth to it.
The rest of the wood to metal fit was ok so we sanded the checkering off and applied a tru oil finish to the wood.
It looked and shot good and we sold it the same year.
