Three Five Seven carbine velocity.....

I have long been a fan of three five seven carbines and find them to be among the most useful firearms to have around the farm (as well as AR15s and 9mm carbines).

Unfortunately, an unnamed member of the board seems to talk me out of all my .357 Marlins for his sons....

A common misconception on these handy carbines is that longer barrels deliver higher velocities. Not so. Please note the measured velocity of various .357 ammo in different barrel lengths. Link below.

One quickly will see that in all but one type of ammo that the highest measured velocity is in the 16" tube.

In that the whole idea is a handy and useful general purpose carbine...16" is a winner.

Sight radius becomes an issue in short barrels especially with those with older eyes....a low profile peep sight is then the answer. Also, while discharged by some as non-traditional, a fiber optic front sight (green works best for me) will improve the ability to hit under almost all situations.

Note on the newer Rossi 92s that have the safety on the bolt there is a peep sight that will fit right into the hole giving the ultimate is precise low profile sighting.

Also, please note while on the "ballisticsbytheinch.com" site the comparisons between the .22 LR and .22 WRM. Note at the 2" mark there is no difference between the two.
