Can expect about 2,000fps from the better 170gr. factory offerings (1950 to 2025fps...some less), which realy isn't all that far behind the real velocity from 20" barreled carbines.
Real effective range may not be the same as the ballistic range...depends on how well you can group and the sighting equipment, The rifle amy be able to kill at 150yards, but the shooter may be limited to less. I still consider 150yards to be the sporting max.
I used a 17.3" 1/2 mag. Winchester 94 carbine for a few years; becoming this odd length after I bought it as a "fixer"...haven't a lue how the previous for the comparison to be valid.

things that didn't work well:
1. Using better shaped bullets designed for higher velocity. Besides the danger of pointed bullets in tube. magazines, these bullets just didn't work all that well at lower velcoity. The light weight 130 and 135gr. bullets designed for single shot handguns DO work well. With a tube. mag., you have a 2-shooter (one in the barrel, one in the magazine).
2. I used iron sights (tang peep). A scoipe can allow you to groupe better, but tempts you past the 150yard limit....psycological, but if you san see the deer so well, we tend to shoot it (in other words, slapping a 20X scope on your 30-30 doesn't make the bullets work better).
3. Can kill game much farther away than 150yards. Bullets start to act like FMJ's (without the bonus of tumbling that military bullets can give). Exact placement can earn game, but it's really not "sporting".
