    I am baffled

    Okay I need a little help or suggestions on this problem.

    I have a Remlin 1894 and before anyone starts I have no complaints with workmanship or accuracy with it.
    What has me baffled is ammo related I hope. I reload my ammo and about 1 out of 4 rounds are misfires. The primers are struck just no ignition. I have to try them 2 or 3 times before they fire. Issue points to hammer spring or primers.
    I bought factory ammo and not one misfire or light primer strike. It fires religiously. I even added a washer to the hammer spring just to eliminate that variable, but same results.
    I use the same type of primers and some from the same package in reloads for my 45/70 and T4. Not one misfire. I even changed the primers over from CCI to Winchester. Same results.
    I even loaded 25 rounds and did not sit the primers or bullets quiet as deep just to try and eliminate head space and too deep of primers. Heck I even changed bullets from 240 gr to 270 gr. Checked the rounds with a caliper against factory ammo and every thing measured the same.

    so any suggestions or input


    When the time to act is here, the time to prepare has past

    Pull the bolt.
    How far does firing pin protrude fully forward ? (0.055"-0.060")

    ps: Always seat the primer fully home. Don't worry about headspace

    I may be off base here but are you using the same primers for 45-70, 444 and 44 mag? The 45-70 and 444 would use large rifle primers, the 44 would use large pistol primers.

    Seat all primers to the bottom, if they aren’t solid they won’t ignite as well.


    I agree above with checking firing pin protrusion.

    I notice from your post that you are using the same primers for your 1894 (I assume its chambered in 44 Mag), 45-70, and Triple-4. Are you using large rifle primers, large pistol primers, or large mag pistol primers?

    I'm guessing the firing pin is a tiny bit too short or the spring is too strong.

    It's been a while, but ... As I recall some primers are 'harder' than others. I believe federal primers provided the best results.

    Large rifle primers are taller than large pistol, and
    would likely/noticeably stand proud of the case head.

    I believe that is true. IIRC--rifle primers can be harder than pistol primers depending on the manufacturer.

    Sounds like a short firing pin. A few thousandths of an inch matters.

    Misfires have several potential causes.

    Too weak firing pin strike. You have increased firing pin strength with that washer.

    Firing pin not protruding enough to create a deep enough strike.

    Primer not being seated all the way. The priming pellet must be crushed against the dimpled primer and the anvil. If the primer is not seated all the way, the firing pin strike must push the primer fully into the base cup before the pellet can be crushed to create ignition.

    Headspace could be too long. The bolt stops short of holding the cartridge fully into the chamber. The firing pin strike wastes energy pushing the cartridge to a stop as it fully chambers.

    The 1894's use rimmed cartridges which headspace off their rims, not a bottle neck shoulder. The bolt position in battery is crucial.

    I'd look at firing pin protrusion, and then consider whether your rifle's in battery bolt position is correct. The easiest way to do that is with a no-go headspace guage. Lacking that, I'd add layers of Scotch tape, one at a time, to the back of a dummy cartridge until resistance to lever closure (bolt going into battery). This will also give some idea of the space available between the cartridge base and the bolt face.

    Once you find out how many layers of tape prevent the bolt going into battery, I will do the same, and we can compare the numbers. Is your 1894 a 44 mag?
