Older Marlin 336 Question

[Judge Blackhawk]

I have a Sears J.C. Higgins Model 45 (equals Marlin 336C) and my question is this.

Are the older Marlin 336 models without the cross bolt safety as strong as the new models?

Any information ya'll can provide on this question would be appreciated.

While metallergy has improved over the years I doubt that a current 336 is all that much stronger than one built 40 years ago. The basic design hasn't changed except for the safety and type of rifling(is yours cut or micro-grooved?). These rifles were designed for the relatively low pressure 30-30 and as long as you stick to factory loads or factory equivilent reloads you shouldn't have problems. The overall condition of the rifle is more important than the age.

Once had a 336 with cut rifling and got an inch group at 100 yards from the bench. Good rifles.

Actually the only one that could give you a definitive answer would be the factory.

as long as we're on the subject...

what *is* that screw on the right side of the frame that slowly works lose as the action is worked? Is this supposed to happen? My 336 and my brother's marlin .22 lever both do this, but on his it's a big ol' knurled bolt that jams the rifle it works too far open.

Is it a bad idea to lock-tite that screw, on the 336 anyways, or should I just continue to retighten with a thumbnail as necessary?

Thanks!
