higher capacity factory magazines/varmint rifles

I know Savage Arms sells 10-round factory magazines for their Savage Predator Hunter rifles. Does any other rifle maker do the same? Cyrano

I can't imagine a need for more then the standard five rounds for "predator" or varmint hunting.

With the 22-250 & .243 you have to stop shooting and let them cool off or you will burn a barrel out in no time flat.

I have hunted coyotes for nearly 50 years and can't ever remember running a bolt-action dry.
You either killed them with the first shot or two, or they will have run clear out of the county by then.

No coyotes, just little sage rats. I live in central Oregon.

Well, you still have to pace yourself if you want the barrel to survive very long.

I had a buddy burn out a new Remington 700 6mm barrel on a prairie dog town in one morning.

Stopping to reload a standard box mag every five rounds isn't even long enough to allow the barrel to cool down on a hot day.

Have you considered an AR?

There are aftermarket kits for many Remington 700 models for box magazines.

If it suits your range needs, you may want to augment your battery with a good rimfire while your centerfire cools.
