Last week end I made and extremely stupid mistake and shot a 308 Win. round through my Ruger MKII Stainless 270 Win. rifle. The rifle held together and shows no visable damage but is being sent into Ruger to be completely checked outand repaired if possible. This is a very good testiment for Ruger rifles and how well they are made. I feel extremely lucky that the rifle did not blow up in my face and can not say enough positive things about Ruger firearms. The 30 caliber Nosler 125 gr ballistic tip even hit the target @ 100 yards but was a little High and right.
Just remember even the most experienced shooter can make a mistake as I have shot rifles for sum 42 years now and thank's to God and Bill Ruger I will continue to shoot and enjoy the outdoors.

You just rediscovered "swaging"!
I've never liked Ruger's auto pistols, but their rifles and revolvers are "Numba One". They make some of the strongest actions available. There's a very good chance your rifle is undamaged, but it is a good idea having them check it out.
I've got an older model M77 myself (.22-250 Varminter), and I'll never let it go.

Well I got my ruger 270 back from Ruger today and after a complete check up tha only thing that they repaired was the ejector. the Headspace etc. all checked out OK and the barrel had to have quite a bit of copper fouling removed before they test fired it. It's amazing to me that it did not blow up but only having the ejector damaged was extremely lucky. As usual Ruger did not charge a dime for the repair. they not only make one tough rifle but the service what they sell with no questions asked. I really was not expecting it back this soon because they have only had it for about a week and a half and seeing that it was shipped from NH to Okla most of the time it was in the mail. Kudo's to Ruger.

Is your MK II a push feed or CRF? The CRF has a slot in the bolt face, while the push feed has a ring of steel around the boltface and a plunger in it.
