Hey people,

Picked up a pretty nice 1888 trapdoor on an auction (new years eve no one was on gunbroker lol). The exterior is rough, some roughness (not quite pitting but almost) on the barrel exterior but it's flawless inside. Paid $500 for it (I stole it I know).

I haven't checked headspace (don't have a gauge...) but I did the old two pieces of masking tape on the back of unfired cartridge test as a prelim and sure enough the action won't close. **Yes, I know this VERY ball-park, but I've used it before and then compared it against a gauge (granted in other calibers) and gotten pretty convincing results.**

Anyways, it seems this old rifle has passed my "field gauge test". Looks clean throughout. There are no competent, reliable gunsmiths who I trust in my area but the next time I head to see my folks I'll go see the family gunsmith-I promise. He says people are overly paranoid about trapdoors and that he has NEVER seen one fail that wasn't compromised by hot ammo.

Now the question: I have guys who have told me everything from "don't fire those guns without severely downloaded ammo" to "cowboy loads only" to "shoot whatever the hell you want through it, if the box says 'for use in all rifles' it's safe in a trapdoor". See poll above

I have shot a truck load of my "cowboy" loads through my trapdoor ( 11 gr Unique , 405 gr lead bullet) as well as black powder handloads. My 1886 issue carbine is in super nice condition and has a through cleaning after firing black powder.
 
Same as Ibmikey, Unique loads and black powder loads. Have also had good success with Trail Boss powder, and Black Powder duplex loads. All with cast lead bullets of 300 gr and 405 gr. This is in an 1884 Trapdoor.
 
Any factory loaded standard pressure ammo with be safe if the rifle is mechanically sound. Obviously stay away from Buffalo Bore, "Marlin only" loads, etc. You would probably get more enjoyment shooting some BP or Trailboss loads with 405gr cast bullets IMO.
 
I have an 1873 and an 1884 trapdoor and I shoot both often. I load a 405 grain cast lead bullet with 32 to 33 grains of H4895 powder. This gives about 1200 to 1250 fps which closely approximates the original black powder loads. Pressure for this load is well within the safe range for these antiques. Be wary of loading with Trailboss as the pressures can run quite high. Check loading data on Hodgdons web site. Also be aware that the original sights on the trapdoor are regulated for about a 200 yd zero and this causes them to shoot a foot or more high at 100 yds. These old timers are capable of 4 inch or better groups at 100 yds with the iron sights if you have the eyes for it.
 
Trapdoors seem to be the threshold for modern commercial loads in .45-70, except for specific higher pressure loads for stronger actions. Stick with the basic loads and you'll be fine.
 
I have read that the standard 405 and 300 gr factory loaded ammo is safe for trapdoors. Buffalo Bore and other specialty hot loaded stuff isn't. Stick to the loads in the manual's listed for the trapdoors and you cant go wrong. If you shoot black powder the only way you can get in trouble is to load with 4F. That's a no-no.

About the time your gun was made, Remington tried an experiment to prove how strong their rolling block rifle was. The filled the barrel halfway up with black powder and halfway with bullets, loaded from the muzzle. They touched it off and got a tremendous roar. And no damage.

The exact same thing happened with a trap door. Maybe they are stronger than we think.

R.I.A. auctioned off one in 30-40 Krag, an experimental tool room gun the Army was toying with at the turn of the last century. Don't know why, maybe they had conversions in mind. There were only a handful of them made. I have no idea if the action was deemed strong enough or why they dropped the project, but these few 30-40 trapdoors are the holy grail of trapdoor collecting. The one I mentioned sold for way up into five figures.
