Re: Replicating the Federal Gold medal match ammo?
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: colt933</div><div class="ubbcode-body">While I agree with all the posts here about finding your node for your rifle, there is something to replicating a known good factory load. This may seem overly simplistic, but here's what I did:
I bought a few boxes of FGMM 7.62 NATO 175SMK ammo from Palmetto State Armory pretty cheap. I wanted to duplicate the M118LR cartridge and had been unable to get any. I figured since ATK operates LC now, and they make the M118LR, and this FGMM said 7.62 NATO and NOT .308 WIN, it was probably the same thing or at least as close as I was going to get in commercial ammo (which I don't think it really is commercial) I shot a few over the chronograph. I then proceeded to load ammo to the same velocity and OAL for my test rifle using LC Match, 175SMK, CCI 200, and Varget. Only one of my components is the same as the FGMM - the SMK. I noticed that the FGMM bullet was crimped in place at the case neck, so I applied a slight crimp as well. The primers were sealed as well but I have not duplicate this.
I then shot these out of 4 different .308 rifles - Steyr SBS Tactical, Rem SPS, and two different Noveske 18" N6 rifles. All shot sub-MOA with this load.
I then substituted the 178AMAX for the 175SMK and adjusted my seater die a little to get the same OAL. Same results: sub-MOA in every rifle we tried them in.
Since then, I loaded up a bunch and when I'm at the range and there's a guy shooting a .308 next to me I ask them to try a few of mine to see if they're accurate in his rifle. All rifles tried so far (about 9) shoot sub-MOA with this load.
Now I have a load for the Steyr that shoots sub-half-MOA. It is custom tailored for the rifle. But this FGMM clone with 178AMAX is remarkably consistent in everything I've ever tried it in. I have shot one 5-shot one-hole group at 200 yards with the Steyr, and had one group with the Rem SPS that was 4 touching and the 5th made it 1" at 200 yards but I pulled it and called it before I saw the impact.
My load: LC Match brass (old headstamps like 70-72 - I came across a few thousand once fired cases and am happy with them), 178AMAX, 42.8gr Varget, CCI 200, COAL 2.805, slight crimp.
Another guy here uses 42.5gr and COAL 2.785 and his results are the same as mine.
So it can be done. You can come up with a generic load that shoots consistently well in many rifles - like Federal does with the FGMM. It will probably not be THE BEST load in any particular rifle, but it will be acceptable in nearly all.
I have another load that shoots equally well in all rifles I've tried, but it's not quite as sexy: 168SMK, Win brass, CCI 200, 41.0gr Varget, no crimp, COAL 2.805. Velocity is low but it is extremely accurate in every rifle I've tried it in and perfect for punching paper at 200. </div></div>
Bingo, That's right where my tests have taken me, with one exception. CCI BR2 is my primer. I was hoping to get a confirmation. I concur with your opinion. Node testing or not, a good quality ammo that test well in a litany of quality test rifles is possible.
I appreciate you sharing your findings.
