Shooting a converted 45/70 - 62 grains imr4198, wool Wad, cci large rifle primers, 300 grain Pittman .452 aeromax sized to .4495 - and am getting squib loads? Same powder and primers. Everything sealed and dry. Not sure what the heck is going on and super frustrated about ready to go back to black powder…

How much hand pressure does it take to push the bullet down the barrel?
Are you using CCIM primers?

Same pressure about since I got it - using cci large rifle primers br-2 same primers I’ve always used.

I've been using cci magnum primers for a couple years since the Federals have been hard to find in my area. I haven't had any trouble with the cci magnums.

I realize going back to black power is a frustration statement, but it may shed light. If the problem persists, you have eliminated the powder. The powder is my first suspect. Squib load in center fire is usually when a shell accidently gets a light load of powder. That is not the case with a muzzleloader. So, if by squib load, you mean it is firing a very low velocity, I begin to suspect the powder has, in some way, degraded.
I presume you have done this, but my first step would be to remove the breech plug and clear the channel and put it in an ultrasonic cleaner. It is a quick thing to try. I'd also examine it closely for any plug issues just from a safety perspective. If everything looks OK, my next step would be to borrow some 4198 from a friend and see if the problem persists.

Clean, clean and clean. Clean the plug and modules. Start with the basic if nothing else has changed.

I cleaned the breech plug but it was completely clear. I guess I’ll try magnum primers? But everything seems to be good. I’m being told that sizing all my bullets to .4495 could be the problem? But they’ve shot great up until now?

But they’ve shot great up until now? Did you clean your modules? Did the builder tell you to size your bullet to .4495?? Size the bullet to fit your barrel only. It’s a feel thing not a measurement thing.

Possibility? I and another had some misfire/ fail to fire due to how we were storing our modules and primers. We had them sealed and when we discontinued this practice the ftf went away. I believe the primers need to breathe in the original pkging.🤔

I’ve had more issues with blackpowder not going bang vs 4198. Open the powder container and smell it. Did it go bad from exposure to heat or-is it soaked w moisture possibly?
The other culprit could be the colder temps. Bullets that were sized to fit well in warmer temps will almost always be looser fitting in cold temps.
Maybe I missed it - but the loading force was never mentioned when asked other than it was the same as before. More details are needed as in 1 hand/2 fingers for pushing the round down the barrel. But 4198 will usually go bang w 1 finger pressure.
Dennis talked about the primers being the issue. Fire some off without powder to check them.
If the primers go bang and the bullets have some resistance pushing down - then it’s most likely the powder has went bad.
What ignition are you using ? HIS/ASG/Direct ?

I’m not sure about my ignition system? I just use the modules and primers? I’ll test my primers.

I’ve stored the powder in air tight containers and I just got the bottle this summer. I’m hoping that’s not it?

Can you post a picture of your plug and modules to help determine what you have?

I also don't do anything extra with my powder just store in the original container in the coolest and dryest area, basement on a wood bench.

if you can try a .40 cal bullet in a sabot, it'll surely have a tight fit to bore and see if it goes bang as it should.

99% sure your problem is loose bullets. Tighten them up some and see what happens.

So if all of my bullets were already sized to .4495 how do I tighten them up? How often do you have to adjust the size of your bullets to prevent misfire/squib? I got into smokeless to avoid the issues of black powder - and so far have been very disappointed unfortunately.

I would never size all my bullets even though my 1st RemPac hasn’t been changed in 8 years. Some bullets even have some spring back. Like all things, there’s a learning curve to SML. Don’t get overly frustrated but be patient and learn.

I got into smokeless to avoid the issues of black powder - and so far have been very disappointed unfortunately. 1- 4198 burns really clean and actually gets a little easier to load after the 1st shot. This isn’t the case w blackhorn 209 -just the opposite. 2- Don’t size all of your bullets to one size going forward. 3- Get a good bullet size established in cold weather- make sure the bullets and barrel are cold. Get the bullet sized so only 1 pass through the die works best. 4- As temps warm up it may get harder to push the round down the barrel. Try running it through the die 2 times. If this works take note of it. If temps get hot -you might need to run it through the die 3 times. 5- Take good notes. The above on sizing the bullets has worked well for me with clean burning powders like 4198. When sizing your bullets write the die setting and number of times through the press. Example : 300 Pitman 3.2 (Die Setting) S1 (sized 1x) If this bullet is too tight in warmer weather -run it through the die again (S2) and it should go down the tube. Likewise if it’s cold (rounds dropping down the tube) and you have (S2). In this case save that bullet for warmer weather. Your results might be different than mine but I used to change the die settings to adjust for cold and hot -or buy separate dies for cold and hot. I no longer need to do this. Again - my results and advice.
