Over the past few weekends, I've been testing different commercial ammo for the RFB.

Kel-Tec claims the barrel is 18", and I haven't measured it, but it seems a little shorter than that.
The twist is 1:11.25".

The ammo I tried was grouped by bullet weight:

.308 - 168 gr:
Federal Premium Gold Medal Match Sierra Matchking BTHP
Hornady TAP FPD
Remington Premier Match Matchking BTHP

7.62x51 - 168 gr:
American Eagle "for M1A"

.308 - 165 gr:
Hornady Custom BTSP

.308 - 150 gr:
Hornady SST Superformance
Winchester Ballistic Silvertip
American Eagle FMBT

7.62x51 - 149gr:
Lake City - Federal

.308 - 147 gr:
PMC Bronz FMJ-BT

Each session started with a clean weapon, and a bore snake was run through the barrel when changing to a new ammunition.
I shot 3 "practice" rounds at the start of each new ammo, then shot (3) three-shot groups.  
All off a sand bag, using a cheap BSA 1-3x red dot set to 3x.  
The red dot of the scope is 3moa.
The local range has a 100 yard berm, with wooden covered benches set in a cement slab.  
I was shooting at a 8 inch round black target with a 1" orange round bullseye.  
 
Every weapon (and every barrel) is different and "likes" different ammo, but this exercise should give a decent overview of some of the more popular brands and bullet weights for my RFB.

Target picture for reference:

.308 - 168 gr:
Federal Premium Gold Medal Match Sierra Matchking BTHP

The "practice/warm-up rounds" of the first volley hit low (at the very bottom of the cardboard stand), which ended up saving me a clean target (I had 4 set-up at 100yds.)

Also, the 4th volley (third picture) should have been a little tighter.  I have a habit of starting out smooth, and then by this 4th volley, got a little excited, and then settled in for the rest of the day...

.308 - 168 gr:
Hornady TAP FPD


in the thrid picture - disregard what looks like a 4th hole in the "8-ring" the true shot from this volley blew the sticker off from one of the previous sessions...

.308 - 168 gr:
Remington Premier Match Matchking BTHP

Note:  I hate Remington ammo (IMHO - it's dirty), so I only did the "warm-up" and two 3-round volleys.  It was shooting all over the target, so I didn't want to keep going and foul the weapon for the rest of the day...

7.62x51 - 168 gr:
American Eagle "for M1A"


In the second picture - disregard the "bullseye" shot, it was from an earlier round (Hornady TAP), and I didn't have any orange stickers to cover it up.  Also, the group looks like 4 shots, but again it was a sticker falling off, so the group shot was only 3 shots.

.308 - 165 gr:
Hornady Custom BTSP


first picture - not sure where the third shot went, but since this was just the warm up, oh well...
second pic - disregard the "bullseye" shot (it is still there from the TAP session (no orange stickers...)

Summary of the heavy bullets:
My RFB loved the "Federal Premium .308-168gr Gold Medal Match BTHP" - about 1-1/2moa
It really liked the Hornady TAP FPD 168's and the Amer. Eagle M1A 168's - about 2moa
The other two were "on paper", but loose...

I don't have pictures of the rest, just my notes...

.308 - 150 gr:
Hornady SST Superformance - loose groups (around 4moa)
Winchester Ballistic Silvertip - excellent at about 1-1/2 moa
American Eagle FMBT - very good at about 2moa

7.62x51 - 149gr:
Federal Lake City FMJ - acceptable at 3moa

.308 - 147 gr:
PMC Bronz FMJ-BT - acceptable at 3moa


-----------------------------------------------------------

So for cheap plinking:  PMC Bronz .308-147gr Boat Tails
For quality work: Federal Premium .308-168gr Gold Medal Match BTHP

Nice report. I havn't been able to break the 1moa yet. My results are close to yours. I even tried DRT ammo. The best I have been able to do is 1.1 moa 5 shot group.  Grin   But for a bullpup in 7.62x51 it is better than I expected. mine is number 177.  Wink

Early number! 

I'm TOJ25 (1825, I think...)

I'm blaming the +1-2moa on the cheap, 3x scope I've currently got...  I know that the short barrel isn't going to produce a "one hole wonder", but I was thinking if the magnification was better, it could be at 1moa with the Gold Medal Match ammo...

 Cool
