No
The Marlin 795 has a built-in feature that prevents the gun from firing without a magazine in place. Though, the modification to reverse this feature is very simple.
There are dozens of models of rifles and a few revolvers that fire the .17 HMR cartridge. Rifles in that caliber are made by Remington, Winchester, Marlin, Mossberg, Savage, Taurus and others.
In short, no. The .17 Mach 2 and the .17 Hornady Magnum Rimfire are two different cartridges- they just happen to both have a 17 in their names. Only use the caliber of ammo that is stamped on the rifle. When chambered in a .17 HMR rifle, the .17 M2 will either not fire at all, or will split the cartridge casing on firing. The HMR has a larger case diameter and length than the M2.
It is so very easy and so much faster if only you can be bothered to use your calculator! 795*345 = 247,275
Yes, may people use lead bullets for a variety of purposes.
dashes and bullets
Bullets were invented in prehistoric times. Originally bullets were not made for use with firearms as they were invented before firearms were.
burning bullets is an ability that only soldiers can use
Hollowpoint bullets will cycle throught both my Marlin 1894 and Rossi '92 copy, both guns are .44 Rem Mag. These guns have digested every factory JHP bullet without any problems. I also use Lyman Devastator cast hollowpoints, these will cycle fine too but sometimes hang up in the Marlin when chambering causing the mouth of the hollopoint to deform slightly, this can be resolved by loading the bullets in .44 Special cases.

Yes. Lead bullets do not wear out the rifling inside the barrel as fast as steel bullets. Still, many people use steel-jacketed bullets . . .
