While it is in violation of the manual, many Savage ML shooters are now tinkering with knurling bullets for a tight fit, and loading smokeless, sabotless.
I've seen most reports of it to be in the .45 Pacnors, but some are also tinkering with the .50's now.

It's not something I have tried yet, but I mjst admit that the idea of doing away with 1/3 of the components and shooting a .45 in a .45 bore is beginning to eat at me just a bit.

.308, shoot me a PM if you want to know more and I'll point you to the information.
