I failed to remove my ramrod from my Savage 10ml2 before shooting. 65 grains of IMR4198, orange mmp sabot and a .458 300 gr Remington JHP. Recoil was very harsh. It was my first shot and thought I did not shoulder rifle correctly. New powder load down the barrel, started sabot and bullet and could not find my ramrod anywhere. I realized what I had done. Got my cleaning rod and pushed bullet down to about 5 inches from breech plug and bullet fell down bore. I had bulged my barrel due to my carelessness. I was fortunate that is all that happened. It was also a testament to the quality of Savage barrels. A part of my ramrod also hit the target at 100 yds.
