DSA SA58C accuracy

My old thread is here:
http://www.falfiles.com/forums/showt...hreadid=240707

This is a NIB SA58C with 18 inch barrel I bought a while back. only shot 5 times so far.

Today, I went out to try 3 different ammo. One of them was again the Federal GameKing as benchmark.

at 100 yards and with 5x Leupold scope, I still had hard time keeping the FAL in a group of 5-7 inches with all the three ammo i used.

OK, might be my shooting. So I took out my Rem 700 LTR with 20x scope, I was able to put everything under 1 inch group so tight that all shots were touching each other.

Might be I got a better scope? I was able to shoot a <3 inch group with my Sig 556 and its plain EOTech red dot at 100 yards.

So, it's the not the ammo, not my skill, what do you guys think?

165 gr Sierra Gameking BTSP.

don't think it's the ammo. already ruled it out with the LTR, which shot all my ammo at 1MOA.

Don't use a soft point unless you plan on loading one at a time into the chamber by hand. Feeding ramp and all kinda other stuff muck up the end of the bullet while shovin it up into the chamber. I found that the matchking bthp works best at 168 grain or heavier.

I doubt it's the bullet. first I'd look at the crappy trigger. After that, everything thing else that gets kicked around under this perpetual topic.

I' going to change out the trigger on my SA58, then, I'll decide if she stays or goes.

As I sit here and think about it; perhaps the accuracy of the FAL & mini-14 are more a matter of voo-doo than anything else. Though it appears the 'mini' will respond 'predictibly' to certain tweaking prcedures.

Perhaps soaking the rifle in the rendered fat of an un-baptised child might turn the trick ?

I have had similar frustration with accuracy. not sure why every one in here is so hostile regarding fal accuracy? I have a love/hate affair with my Para carbine. I have settled with an Eotech due to the accuracy issues. I get about 2.5 inch groups at 100 m. never better.

10-shot groups fired from the magazine?

I would be fine if it's 2.5 inch. it's a battle rifle.

FWIW, that 165-grain bullet is a little heavy by comparison to the bullet usually intended for use in a FAL.

Can you try something in the 146-grain range?

I don't think the 165's should do as poorly as you experienced.
But, a different load (and lighter bullet) might give other results.

The FAL rifle (FN data) has a twist rate of 1:11.9 inches. The standard NATO bullet weight was 146grs. This is a good match.

Anything heavier is going to require a faster twist rate to stabilise the projectile. 168grs is too heavy, like Gary said.

Think of the 55grs. (M193) vs. 62grs. (SS109) discussion. An older type rifle with 1:12 rifling (made for the original 5.56x45 round, M193) is going to struggle to group properly with the newer, heavier bullet.

You know what? These guys are right about the weight of the bullet. I was thinking about my barrel which has a 1:10 inch twist. The lighter the bullet the longer the twist.

I have a dsa Para that shoots the 168 GM's very well. Our military 30 cal sniper guns that have a 1-11.7 twist barrels shoot 175 GM's very well.

You are quite right.

I'm just wondering if the OP's gun doesn't like that load for some reason.

168 vs 146 should not - all by itself - be reason for accuracy problems.

I shot FGM 168's in my IMBEL barrel gun, and accuracy was acceptable - although not awesome.
Then, no ammo is awesome in that gun.

Are you sure the scope isn't moving on you? I'd try shooting it with the iron sights to see what kind of groups you get just for comparison.

I took the Leupold scope off the FAL and mounted on my Sig 556 today. I got less than 1 inch group with 5 shots (2 went through the same hole.)

I mounted an EOTech on the FAL, but still got erratically grouping 5-7 inchs. With my Sig 556 and EOTech, i can easily do 3 inch.
