OCW: GAP 300WM 190gr SMK RL-22

I've had this rifle built in 2007. It was built by George himself. I've shot match grade ammo, reloads and everything in between. I've never really been able to get anything under .75 MOA until today.

I started fiddling (AGAIN) with the 190gr SMK's and Reloader 22 again today. Doesn't GAP base most of their rifles off of the FGMM round?

According to OnTarget the best groups today were 0.597" and 0.599" both at 73.4gr.

Load Data:
Federal once fired brass
190gr SMK
FGMM 215M
RL-22 (Charge as shown)
2.873 (Base to Ogive)
Set at 2.863 (0.010 off lands)
Reloaded on Forster Co-Ax
All charges weighed on Acculab
Redding Type-S Competition Dies w/ 0.335 bushing

Sierra's Max load was 72.7gr (I never saw pressures signs on any of my stuff)

Below are my targets. Any thoughts?




Is it me? Is it my shooting?

COUES 7,
I would just like to know if you have been in contact with ga-precision and with george himself. what was said and why didnt it go back..
I have a 338 lapua being built as we speak ,,,with a 3/8 or less guarantee with match grade ammo.I hand load so after break in it,s up to me.
They have a lot of rifles out there shooting with my gurantee and less.
So what coarse of action did you take.

Re: OCW: GAP 300WM 190gr SMK RL-22

I've talked to George multiple times and have opted to keep trying. I'm damn near ready to give up.....

Here's a little background on how I'm shooting my rounds:

I should have explained my firing procedure. I'm doing EXACTLY as you described. I shoot a single round of a particular charge, put a Coleman air bed infiltrator into the barrel and let it run for 2 minutes. Then shot a single shot of another powder charge and repeat the cooling of 2 minutes.....All shots were done round robin.

One set of targets was shot a 0630 this morning and then another set was shot a 0900. I couldn't get any consistency out of the 1st set (written in red) so I shot the 2nd set (written in blue).

All shots were taken prone off a bipod.

For a $3500 rifle that is guaranteed to shoot 1/2 MOA or better is damn ******.

Just my opinion, but I think your too focused on powder and not enough on seating depth. I've seen groups like that shrink to .2 with just .010 difference in depth. I've also had real good luck in my 300 with H4831sc. Good luck, hope she comes around.

Do you recommend coming in or out with the seating depth?

Take your best charge so far and try .05 increments longer and shorter till she comes around. Start with a clean fouled barrel which I'm sure you are. And don't forget the cleaning rod in case you jam one in the lands.

I'll start with .05 increments next Friday. I still don't even know what to focus around is the only problem. I know tight groups are great, but when it comes to OCW that is not the original intent. I don't see any real consistent Point of Impact (POI).
