SAR3-55gr or 62gr?

Okay,I'm aware that in an AR platform,it makes a big difference in accuracy which ammo you use.First,is it the same in an AK?Second,who has experience with both bullet weights,and which is the more accurate of the two?Thanks...

I do not know what the twist rate is on a Romanian SAR-3 barrel, so I do not know for sure what bullet weight is correct.

But...

I do know that Bulgarian barrels from Arsenal and KVar that are chambered in .223 Rem. (5.56x45mm. NATO) have a 1/7" twist which means 62 grain bullets would be more appropriate.

Now, how comparable are Bulgarian and Romanian barrel twists? I’m not sure.

You can test the twist of your barrel by running a bore mop on a cleaning rod slowly down the barrel while you count the number of times the cleaning rod fully revolves.

1. AK barrel is 16"...so 2.3 revolutions, or MORE than 2 full revolutions = 1/7" twist = 62 grain bullet.

2. AK barrel is 16"...so 1.8 revolutions, or LESS that 2 full revolutions = 1/9" twist = 55 grain bullet.


Hope that helps at least a little.

the folks at aim surplus told me that the sar 3 barrels were 1/9. unfortunately they could not tell me for sure the twist of my wasr3 barrel.

l've fired both out of my WASR-3 and the 62 grain seems to be a bit more accurate, but not by much.

I have a SAR-3 in which I have fired a pretty wide range of ammo, both 55 gr. and 62 gr. Accuracy has always been acceptable but it seems to like certain brands better than others, as oppossed to bullet weights. Mine really likes the Federal brown box 55 gr. Ball and the Winchester/USA white box 55 and 62 gr. FMJ, with almost no difference in accuracy. The best thing to do is take your rifle out with several different brands of 55 gr. and 62 gr. and see which shoots best out of yours. I hope this gives you a good place to start.

Assuming your twist rate is 1:9, it will not matter that much for accuracy which one you use, 55 or 62 grain. What will matter more is the capability of your rifle to shoot accurately with certain brands or types of ammo. IF accuracy is your goal, personally I would try some Black Hills 52 grain or 55 grain and see how you do with that. I have very good success with Black Hills and Federal in bolt guns, but for the AK's I usually use cheaper stuff because mine have not been capable of much better than 2-3 MOA.
