Great rifles!
Modern M70 are in theory safer than Pre-64's due to better design overpressure gas venting.
Now the bad...
1. Install pillars (pillar bed) for the action screws
2. Devcon/glass bed the action
3. Swap out action screws for metric head (won't find Imperial sizes in Africa!) action screws. Pack at least two allen wrenches in different bags/cases when going to Africa! You may loose one.
Steps 1-3 will ensure your rifle will hold its zero no matter how much your wood stock dances to weather changes! Also, the allen screws allow one to remove the barreled action from stock and easily replace it for maintenance, cleaning and oiling, and if desired, to pack into a shorter hard travel rifle case.
4. Swap out magazine spring for a M98 Mauser surplus spring. These do break! I've carried extra to Africa for AH members and provided same to AH members stateside.
5. Swap out extractor for Pre-64 M70 extractor. If not available have a gunsmith fit a M98, P14/17 extractor. War surplus parts were designed to be soldier-proof! Again, I've carried extra to Africa for AH members.
6. Finally, there have been reported cases on AH of striker springs breaking. Rare but has happened...
I haven't swapped out the striker spring on my M70 Classic CRF rifles, yet... I may look into Wolf springs since that is their primary business.
Make up some dummy rounds and practice loading, dry firing, and working that bolt fast and hard like a buffalo is charging you, and reloading in a hurry!
Below are photos of my homemade dummy/inert rounds for 458 Win.
Notice that I used round nosed bullets for the first batch?
Then, I turned the bullets around for a very flat base to be fed from magazine into the chamber.
If your rifle will feed backwards bullet cartridges, it will feed most any hunting rounds you come up with!
To make dummys like these;
- Full length resize
- Drill holes in base for positive identification that these are NOT live rounds!
- Remove brass shaving from inside case
- Fill primer pocket with hot glue from a $10 hot glue gun or install pencil eraser/hard foam
- Finally, if excessive compulsive like, me, squirt hot glue into case via drilled holes. Add enough glue to weigh what missing powder and brass would weigh. I have also inserted a handful or BBs instead of glue. Your choice... This step is not necessary but for my reloading from my belt training, I want to be as realistic as possible!
