Mosin's definitely go BOOM, haha. I'd suggest getting a recoil pad. These things tend to cause some pain around the 100 round mark
Bah...suck it into your shoulder and have at it. Some folks in another post were rambling about how hard kicking the M44's were, so I went out and hammered 100 + rd's through mine Notice the middle row in the spam can is missing, it was a full can about 45 min's before the picture was taken...and the clamp on bipod lasted about 15 rds on the 39 too

The 44 got so hot that the cosmo started oozing out of the stock ( my 13 year old was shooting the M39, and it yes it's got a rubber recoil pad...she is 13 after all ).
Nary a bruise. But you've got it pull it tight and bear down on it, It's not made of crystal, hang on to that sucker.
And BTW...no offense intended
