Then yesterday I was shooting mine and verifying zero. I really feel I was being as consistent as possible loading and seating bullets. Needless to say I had a huge pressure peak shot also. I have shot large bore guns up to a 460wby. I thought I had blown up the gun, and the recoil was easily more than a .458win.
Has anyone experienced this and or what are we doing that is causing this. Needless to say I dont want this to continue.

I have never experienced such a thing.

Whats different - Extra tight bullets ? Different bullets?

I am new to muzzle loading and have only fired about 400 shots through one. I have been reloading and shooting for over 40 years, so am reasonably experienced in firearms. My buddy is getting into it also so we had a bullet test day recently. We were pretty careful in our loading procedure. He had a insane shot that had pressure through the roof. The recoil was so bad it it bruised his entire shoulder and upper arm for over a week. He could barely move his arm that day, and the muzzle blast was so loud I thought he had blown his gun up. We thought about it and he was sure the bullet was seated. We were using pre-measured powder charges individually packaged.

Wow! my first reaction was a 'double load' either the powder or the bullet... but I am just not seeing you make that error.
So I would ask:
1. Which powder were you shooting?
2. Which ignition system?
3. What was the load - volume or weight?
4. What was the weight of the projectile?
4. Which sabot or was it a full bore conical of some type?
6. The shot you experienced the how did the projectile load - how much pressure to get it down the barrel?
7. Is your ram rod marked for that load?
8. Where did the projectile hit the target compared to the normal shots?
Another question that I would ask... do you or your friend have any more of those pre-measured loads left? If you do I would dump them individually.
1. Look at each load to verify that the powder granules all look the same size
2. Does the volume of each dump appear to be the same?
3. Re-weigh or reload volume measure to verify that you have what you think you have.
I have some other questions but they are way out there - so I will wait for your and others responses...
Glad everything seems to be OK

He was shooting 300gr Harvester in their crush rib sabot. 110gr charge.
I was shooting 290TEZ in their blue sabot. 120gr charge.
Loading pressure exactly the same as the others shots.
Ram rod is not marked....yes I know but we just nalized our loads. I had been using a range rod....first time using the rifles rod today. I think I will set my range rod depth gauge the next time.
Don't remember his shot but on mine today it hit about 12" higher. The recoil was so bad I was shooting on a front rest rear bag but holding the forearm. The gun almost flipped out of my hands. If not for the thumbhole stock I might have.
LOL...yes and I just weighed out another 30....yes I will be checking/re weighing them.
Yes I stand the tubes together and they look the same.
He thought possibly did not get the bullet seated fully. I know mine was seated. The only thing I can think is I dumped two tubes down it....only thing I could have done. I was specifically trying different methods to fully seat the bullet so I could figure out what I would do hunting (no range stuff with me) I was only taking out 2-3 tubes at a time from the cooler to the bench because I had to let it cool after 3 shots. Not saying I didn't but I wont bring out multiple tubes again. One at a time.

You mentioned that you measured the powder and you also said you weighed your powder out. as far as I know, you don't want to weight BP it is done by volume only not weight. do you bounce your ram rod when loading or just push the bullet down. with a rod not marked it could be off the powder just a little, if just pushed down & not bouncing the rod. Stay safe out there.

Tagging along

I weigh 95% of my charges as they can be weighed and or measured by volume. My volume I have experienced greater weight (hence more powder??) by measuring by volume. Also if you tap or bump the measure it will take a lot more powder...again...makes me believe more powder.
No I don't bounce...it against the bullet/powder. I just press it down using the range and or ram rod with the starter ball as a handle with the ram rod. I put quite a bit of pressure but obviously I did or am doing something wrong.
I am going to dump my weighed charges into a measure and track if they overfill or underfill it to see if I am getting any variation.
