| DPMS .308 "Key Holing" Shot my DPMS .308 carbine for the first time a couple of weeks ago (doing the barrel break in procedure as recommended) and noticed when I checked the target (200 yards) that the bullets were key holing. Ammo was Magtech 150 gr. FMJ Are the .308 rifles finicky with ammo ? Any other suggestions ?

| What was the drop . . . . . . at 200 yards from, let's say, being sighted in at 100 yards? You may have had some underpowered ammo? Also, what bullet design did you have? I feel a little more info is needed as a .308 should not keyhole at 200 yards. |

| It could also be the type of paper used for the target. Try some other targets before worrying too much.

| My guess would be wrong bullet weight for your barrel twist |

| I can't see a 150gr .308 having issues in a 1 in 10 barrel.  I would look elsewhere first before blaming the gun. Anything is possible though... |

| I would try a different manufacture of ammo first. Magtech isn't the best |

| The Magtech ammo was solid point full metal jacket. I didn't think Magtech was a top name but they gave me a box with the gun. I will try some Hornady 168gr. next time. Thanks guys !
