I've had 3 of the new FN M70's. One featherweight and two extreme weather. The featherweight wouldn't feed properly and the area to depress the bolt release wasn't inlet properly and it was virtually impossible to remove the bolt. The first extreme weather I had had a 1/8" wide circle of tooling marks 1/2" from the muzzle and a fault in the chamber (more tooling marks) that resulted in fired brass having spiral shaped protrusions on the brass. It also had a large gauge on the conned breech. The EW I have now is perfect but I'm 1/3 on the new and improved FN m70's.
I've had 3 T3 lites (243, 338 wm and a 6.5x55). No longer have the 243 or the 338 wm but they shot lights out and were perfect right out of the box. The 6.5x55 is flawless and accurate, again, nothing I had to do with it.
....one is clearly superior.
Advantages to a M70:
Beautfiul wood finish (FW)
Higher quality polished bluing
wonderful trigger - better feeling than even the Tikka. It's an amazing design
best safety in the business - complete disengagement
controlled round feed
conical breech face
Twist disassemble bolt - easy maintenance
no plastic parts!
Fixed ejector
Massive mauser style extractor which holds more than 1/3 of the rim of the cartridge
3 position safety
Pachemayer decelerator standard
No need to remove magazine to load rounds (solid top receiver on t3 makes this necessary)
Integrated steel recoil lug (T3 has aluminum)
Shot and Long action receivers (T3 has one size fits all)
Advantages to the T3:
Plastic is lighter, I guess.
70 degree bolt lift
better for road hunting because of dbm
umm....maybe....nope. Can't think of anything else.
A few things to be said here imo:
-how pretty something looks has nothing to do with superiority as beauty is in the eye of the beholder.
-there is nothing high quality about the polished blueing on the fw. Supergrade yes, fw no.
-the m70 trigger is not superior to the t3 trigger. If it was, people wouldn't want the old one back.
-please explain why crf is important in anything other than a DG rifle. Tikkas feed upside down and have single stack magazines.
-my glock has lots of plastic and my sig doesn't. My glock keeps going when my sig won't anymore.
-solid top receiver means a more rigid action and having dropped my share of ammo when it's -30C and my fingers are numb while dropping the hinged floor plate a magazine doesn't sound all that bad tbh.
The t3 also has a 1moa accuracy guarantee from the factory. M70's don't, if winchester tested all their guns like tikka does and had the same quality control the two lemons I got wouldn't leave the factory and they could guarantee moa accuracy like the tikka. But since winchester makes way more guns than tikka does it isn't going to happen.
The barrels on the t3's are excellent, perfect crowns and the bore is smooth. The machining on the receiver is perfect. My EW that cost almost twice as much and has burrs, etc on the receiver.
For the money the t3 is the way to go. It's light and accurate. At ~$200 more for the featherweight (nothing featherweight about it, it's heavy and the stock feels like a 2x4) it's not worth the money imo.
I most certainly like my extreme weather but it costs almost twice as much as a t3.
