historically the other guns was M-94 winchesters and the like....they was not ever a match for the bolt action and are not today.
I've seen Remington pums do very nice groups.....and I suspect Browning's BLR will show the targets some good performance and again I've also seen the BAR shoot very well. H&R handi rifles also have fared well as a "shooter"...

Ya know what?????....I just don't know.....but we never see anything but bolt action rifles at shooting matches do we?

Maybe someone can tell us why...this much I can say...I've never found a trigger on a pump or lever or auto as fine as some of the bolts I've used.
