I did something like that.
Had a Remington 22-250 700VL with the heavy barrel.
I was shooting 52HP bullets in Jacketed. I was shooting 55 Gr home cast lead gas check bullets.
In the end, I shot a jacketed bullet with a jacketed charge of WW 296. I DID happen to be usig the chronograph at he time. It went 4200 fps.
I got sprayed in the face with powder. The bolt would not open.
I took it home, used a hammer and block of wood to open the bolt. The handle broke off.
I sent the rifle to Remington. They took it apart and replaced the bolt and barrel. I got the stock and reciever back.
I pulled bullets and weighed charges until I finally figured out that I had used WW 296 instead of WW748. YES a stupid mistake.
I wrote a second letter to Remington expaining exactly what I had done. They shipped the rifle back to me all repaired. The invoice stated NO CHARGE due to Good Will. I think it had a lot to do with me admittig what I had done wrong.
That was maybe 10 years ago. I still shoot that rifle but gave up cast bullets.
Just so you know, I shot a 14 Shot group at three hundred yards 5.5". I am proud of that one, Cast Bullets I made in my garage and worked up my own load. It was a max charge of SR4759 with a 58 gr gas checked cast bullet of pure linotype going 2800 fps.
NOW I KEEP ON LY ONE POWDER NEAR MY LOADING BENCH
