difference in 7.62x54R ammo

[jon1985]

I am looking in to buying some 7.62x54R ammunition. I have noticed 3 different 'bulk' bullets.
Option 1 is 147 grains in crates of 880 rounds
option 2 is 148 grains in crates of 880
option 3 is 150 grains in crates of 1000

They all say fmj and corrosive.

Whats the difference?

Thanks

that would just indicate the projectile weight. projectiles are weighed in grains. 150 weights 3 grains more then 147...etc. its not a big difference in weight. you shouldnt see much difference in point of impact with those 3 choices.

Different plants made those. You'll see the same differences in 7.62x39 ammunition (number in a crate). Otherwise they are equally corrosive, with just a different weight bullet/powder load and equivalently different recoil.

Russian 147gr
Bulgarian 148gr
Chinese… 150gr

I like the Russian stuff, no complaints from me.

1000 rds crates that Canada ammo sells are Machine gun ammo. Its ok for plinking but not for sniping. Ammo itself is virtually new 2011 production, but at the crate there is a label with list of machine guns that use this ammo and +/- accuracy at certain ranges from these machine guns.

None of them are bad choices, but a lot of it comes down to what is available to your local? Shipping ammo crates can kill a good deal.

Forget about the "corrosive" thing, these guns still fire a hundred years later from shooting it. Non-corrosive is a marketing gimmick to sell you ammo for 3 times the cost. As any gun, clean it after you shoot it.

The Chinese machinegun ammo cuts less than MOA in my open sighted MN's. Harold

i would find out what kind of projectile it is. most likely they are all steel copper wash. the copper wash stuff allegedly wears down rifling in the bore maybe twice as fast as actual copper jacketed bullets.

I have not heard this and am curious about this. Can you post a link? I've got a about 2/3 of a crate of copper washed Norc 7.62x39mm ammo for my SKS. It would be nice to know if I am wearing out the barrel. Thanks.

I really doubt that you will have any problems with the barrel wearing out,these rifles were made to be abused.

Copper wash is usually referring to the case. The bullet is still FMJ, thick enough to allow proper rifling grooves. Steel on steel would not just wear the barrel, it would probably Kaboom. As a minimum, there would be a lot of sparks out the muzzle.

Corrosive ammunition means there are salt residues from the powder. Most barrels in sks are chrome lined so it does not rust. Further to this, bullets that travel at only 2400 feet per second take a long time to wear out a barrel, as opposed to rounds that travel at 3400 fps. Surplus ammo will not wear out your barrel. As any gun, clean it and oil it after you have it out. These old rifles still work today because some guy who never went to school, or could read or write cleaned them after they used them. Neglect is the only thing that damages these rifles.
