It depends on what you are going to shoot it thru and what you expect.
If you want accuracy or a clean gun afterwards then look somewhere else

If you are just going to blast away, then it is great ammo

But the saving on ammo well out weighs the cost of extractor for either 1911 or ar15

The .22lr wolf march is good stuff, is quite accurate, great for bolt .22
doesn't alway have the power for sems though
