This hereOn my Marlin 336 I remove the lever, slide the bolt out and clean the barrel from the rear. This also lets me clean and lube the internals.
Really hard to clean a 99 Savage another other way than that...I asked this exact question to a renowned lever action gunsmith with 50 years experience. The gun is a Savage 99. He told me to use an aluminum rod and clean from the muzzle. Sounds scary but the guy’s forgotten more than I’ll ever know.
I love my 99, it's a takedown. Easy as it gets to cleanReally hard to clean a 99 Savage another other way than that...
Wouldn't surprise me any if thats what he has...
