| Lots of talk about different type actions: Pre '64, Winch 70, Mauser, etc. Can some one highlight the differences for me. Photos of each would probably be worth 1000 words. I have a FNH SPR that they claim uses a pre 64 "style" action. Whats the diff?? |

A pre 64 style action is just like a mauser 98 action. A post 64 action does not have the fixed extractor and has a spring loaded ejector. A pre 64 is a much more positive feed system but unless you like to fire your rifles upside down you will see little if any functional difference. As for other action types, well, they may number in the thousands. |

A Pre-64 action on a Model 70 will only eject the spent brass as far as you want it to. Ejection force is equal to how hard you yank back on the bolt. If you're keeping your brass for reloading or conservation, it's easier to keep it right where you want it. A picture isn't even going to do it justice, you need a video clip showing what pulling the bolt back slowly does on each one. On the pre-64 the cartridge will just stick up then almost fall straight down; on a post-64 once you get it back far enough, the spring-loaded ejector will send it flying. |
| I appreciate the ejector info but I was more concerned with the strength advantages of one over the other ro whatever makes the pre 64 so desireable. Also the safeties. I was shooting a friends mauser actioned .25-06, it had a safety that actually was on the rear of the action that flipped up towards the scope as opposd to most safelties sliding parrallel to the barrel. According to him the rifle was built with a GERMAN mauser action which is different that others claiming mauser lineage. the Rem 798 says its a mauser action but I dont see the large safelty that my friends had. |
The ejector (extractor to be precise) really is a big part of what makes the pre-64 Model 70s more desireable. That's the only one that I know of that has a "pre-64" issue, not that I've looked in much detail. The pre-64 Model 70s have an extractor and feed system from the Mauser 98. It's not really 'stronger' but it was less prone to jamming, and as I mentioned had a better extractor that was totally driven by muscle power and not by a spring. With controlled feed, the extractor grabs the rim as it is stripped instead of what happens in most automatic or semi-automatic weapons, where the extractor pushes the round into the chamber and then snaps over the rim. The only other non-cosmetic difference is the safety, which is 3-position on the pre-64. Full forward is 'fire', in the middle it won't 'bang' but you can operate the bolt, and all the way back is safe and the bolt will not operate. |
