30SF issue

First let me say this is my first post here. Glad I stumbled in to the forum.

I have a 30SF and so does a friend of mine. We went shooting and he and I both noticed that mine fails to go the distance his does. We were both shooting fmj blazer brass and the rounds from my 30 were dropping much sooner than his. We swapped to see if maybe my grip was the issue but swapping showed it to be the gun itself. Any insight? Thanks in advance.

Huh??? What do you mean by "dropping much sooner"? Were you shooting out to 200 yards?

Do you mean you are shooting low? If so you are not using a proper grip or trigger technique, and/or anticipating the shot, and jerking the trigger.

I mean we were at 7-10 yards shooting paper targets, rounds from my 30 are much lower than that of my friends 30. We switched to see if it was me or the gun and it was the gun.

Was one of you shooting on one side of the equator?

30SF issue

Your barrel obviously has a leak and it's bleeding pressure. Try putting some bubble gum over the chamber hood and see if it blows it off.

As it turns out each of us were, in fact on one side of the equator.

I'll hook up my air hose and see if the gum pops off.

Yes it was shooting low.

The trigger pull is probably different between the two, not enough for you to notice but enough to show up on the target.

If you're doing a full trigger pull for every shot, trying using the trigger reset for every shot after the first and you should see a big difference.

+1 for the trigger pull difference between guns

Some weird things happen the first time out with some guns. Another trip to the range and 200 or three hundred rounds through it and you will know for sure if it is you or the gun.

The issue may just go away with break-in or change of ammo. A different ammo may be dead on or shoot high, low, right or left.

If you go to a range to shoot there are often people with a lot of experience, ask one of them to shoot it or if you know of an experienced shooter have them put a few rounds through it. Low left sounds like trigger pull control.

You didn't mention if the sights were identical on each 30S.

Thanks for the advice guys. I'll try the different pull and also others at the range.

And yes bados. Same sights.

The G30 should have a 6.9mm tall factory rear sight, denoted by a short dash on top of a long dash on one side of the sight. Sometimes though when benchrested at the factory a particular gun may have a drastic enough shot placement difference that they use a different height rear sight for elevation or drift it slightly for windage.

General Glocking

My guess is still the trigger pull unless one of the guns has aftermarket sights.
