This wear goes without saying but again how much more I couldnt truthfully answer. I have heard it brings it down to 800 rds per 1 T.E. loss Any takers out there with the real answer? RIck B |
It's not the bullet weight so much as the powder thats the problem. If you aren't using something that burns similar to IMR4895 or 4064 you are asking for trouble. You can load heavy bullets in the M1 and shoot them but don't try and "hotrod" them downrange. Yes trying to shoot 190grn HPBT Match rounds at 2700fps at the 1000yd line will work and won't damage the op-rod due to high "port pressures" it WILL beat the rear of the receiver up though. This has happened with M14's and similar loads and it cracked them badly.
I might add that most commercial "hunting ammo" is loaded for bolt guns NOT M1's. They have slow burning powder that has increased port pressure which is death to M1 oprods. It's not "if my oprod gets bent it's WHEN, while using hunting ammo.
As for TE thats a hard question with many answers. It's probably safe to say that unless you are a "serious" shooter you will not notice any appreciable wear in your rifle no matter what you shoot in it.
Story to go with that:
Good friend has a rack grade M1A and shoots nothing but surplus in it (steel jacket, copper, whatever). He buys ammo by the pallet if that says anything and shoots conservativly 1000rnds a month. I remember checking his TE one time and it was approx. "5" well nearly 7 months later it's now a "6.5" so the 1,000 rnds to 1 line of wear doesn't mean much to me. I think it might mean each line is 10,000 rounds! (grin!)
Point is he shoots alot and different ways (Match or just rapid fire), he uses the rifle like a normal "grunt" would use it and it's holding up fine.
I think the TE gage is only realy usefull for "haggling" a price at a gunshow. Bottom line is how does the rifle shoot??
