Reising Action Bar

That's been done, not done very well, but it has been done

 

 

The amount of weight one would need to add to get a significant rate reduction is basically impractical. And considering that it is the known-to-be-fragile bolt which drives the action bar it might not be a good idea even if it could be done.

 

Discussed at length here:

i was looking for a winter project, was thinking hammer,and action bar, make out of tungsten.

and keep weight in line not hanging off end of action bar, to put a bind on bolt. If it has been done,

how much weight was added?

If you read the comments below the video I posted, +12.75 oz. gave a rate reduction but +15 oz. led to malfunctions. However you need to think about the effects of adding mass has on other components. The Reising's mechanism is notoriously fragile with both the bolt and the action bar being prone to failure. Adding mass to either of them or to the hammer is likely to increase the rate of failure.

 

The better solution would seem to be the one proposed by Vern21: reduce the energy input by reducing the bullet weight to 185 grains. No modifications to the gun required, ROF reduced and increased durability by reducing the amount of energy the system components have to dissipate. No cost and no downside.

I had a couple of boxes of 185 wadcutter target loads that I picked up somewhere in my dealings . Decided to try them through my M50 for giggles and laughs . To my dismay , they all fed and functioned fine and the gun shot a lot smoother .

I've found the 185 grain Winchester FMJ to be an excellent round for the m50 - felt recoil/climb are substantially diminished, and the rate of fire is decreased, although the ROF change seems pretty modest, just gauging by ear. I've also experienced exactly zero malfunctions using this round with all stock springs.
