How dirty is the Remington stuff in WMR? I stopped running Remington in my long rifles a long time ago because of to much build up. Remington brand will plug up my 10/22 faster than anything.
I didn't find the Remington ammo any more dirty than anything else I have used. The accuracy was superb, however. I haven't used that load for anything other than crows and starlings, so not sure how it might perform on larger critters.
I have a new .22 mag rifle now (Ruger 77/22) that shoots Winchester 40 gr. hollow points really well.
Here's a couple of rifles I have used and some of the results.
Marlin
Ruger 77/22 magnum
Here's yesterday's Ruger 77/22 kill with the 40 gr. Winchester HP.
Also, a kill about two years ago, again with the Winchester 40 gr. HP.
