To revive this thread a little I'm upgrading my 1.5 MOA Challenge result (see post #139). Haven't shot the M305 much since the Fall having been distracted by a new AR but took her for a spin today even though the conditions were frigid. The last tweak was bedding the heel of the receiver into the Blackfeather stock. After 5 warm up shots on a different target with Norinco bulk, I switched to this target using my ol' regular load of 39.5 grains of 3031 under a 168 BTHP.
Net results, Average 1.169" (1.117 MOA), max group size 1.452" (1.387 MOA), min group size 0.731" (0.698 MOA). As Tony has said, these are getting too easy. Will definitely have to take out to the 200 yard line.
That's some really nice shooting

I had forgotten all about this thread. Now this closet M14 lover is chomping at the bit for some decent weather. I've got 3 Norc's in the safe (love them) and recently acquired an M1A Loaded which shot about 2-3 MOA with cheap ammo (Norc and some old Czech stuff) and about 1.5MOA with XM80 in a Boyd's walnut stock. I've now set it up in a JAE-100 stock and am really hoping to at least scare MOA with hand loads. I've got a bunch of LC brass, 168gr. SMK's and LC 147gr. bullets and H4895 to work with, and am really hoping to meet this challenge once we get a decent day (the last month of weather here has been terrible!). Come on spring!
Is there an importer for these stocks or can I order direct

Wolverine used to import JAE goodies... not sure if they do or not anymore.
Well, I didn't beat my old record, but I blew the 1.5 MOA challenge out of the water! I didn't shoot five 5-shot groups and I didn't shoot at 100 yds. Today I shot one seven shot group and three ten shot groups all at 200 yards. Average group size was 1.165 MOA. Results posted below...
I took a few loads out to the 200yd range today to prepare for my long range journey. They consisted of LC cases, sorted by weight, trimmed to 1.995", sized to 1.628", BR-2 primer, Hornady 178 grain HPBT's and RL-15. Charge weights were 42.4gr, 42.6gr, 42.8gr and 43.0gr. COL was 2.850."
If you missed it, I put the M25 in my Hueygunner kevlar stock and relieved some old bedding material to get it to fit. It's tight, but technically still un-bedded. Results were very good and I settled n 42.8gr as my optimum load. I had not cleaned the barrel at all in any way since my last range trip.
I had an oddball amount of 42.4gr loads so my first group was only seven shots. The group measured 2.529" or 1.207 MOA.
10 rounds of 42.6 grains resulted in a 2.465" group or 1.177 MOA.
10 rounds of 42.8 grains produced the best group of the day at 2.252" or 1.075 MOA.
Things started to open up again with 43.0 grains which measured 2.519" or 1.202 MOA.
I tried to chrono the loads, but my CED M2 was acting weird. It said all my loads were in the 2350 FPS range. That can't be! The same loads last trip were chronographing at 2675 FPS! I don't trust to chrony at this point. I'll have to try again some other day.

It's calling you! Get her out there and shoot!
Thanks! This rifle is soooo fun! I actually just put my other LRB into a SAGE and it shoots good too, but I've hardly had the desire to mess with it now that I have my M25 shooting so well.

Hi All,
I'm finally back in action after almost 6 months away from the shooting scene. Got out today with my modified Norinco 14S to try the challenge again, only the second time I shot it since the mods and had high hopes....Sigh...
It is a 2007 Norinco M14S that I had originally installed in a Blackfeather stock with no other mods except the M14.ca recoil spring guide and spring, shot over 2000 rounds with no malfunctions but the thin barrel caused so much stringing that it was making me crazy so I installed a springfield take off medium barrel and bolt from Tactical Teacher and a USGI gas system from Treeline.
The rifle now has the Norinco reciever, trigger group, flashhider, and op rod, the parts noted above and an M14.ca sight base with a Bushnell 8-32 scope.
My attempt today resulted in a .987, 1.232, 1.324, .712, and .......1.560 group. (always rush the last group right?)
No excuses, the rifle can do it, we will see eventually if I can.

Might have to have a go at this. Was doing some load development today and the group below was the best, so far, 1.404" so 1.34MOA. 168r Hornady HPBT over 40.8gr of IMR-4895 in Federal cases. Rifle is a '09 Norc, I think. Shimmed USGI gas system, SAI muzzle brake sitting in a USGI fibreglass stock with a reinforced front end but not bedded yet. The question now is do I stay content with that group or keep chasing the node with some loads I had made up with Benchmark that had some promise...

Nice group! You know you've got the tiger by the tail, no point even pretending that stopping now is an option
Went back this weekend with 50 rounds to try the challenge again, made it twice!!!
Norinco M14S with Springfield (SAI) medium weight take off barrel and Springfield (SAI) bolt, USGI gas system, original Norc Op Rod and Trigger assm.Bushnell 8-32 power scope. M14.CA casm mount and Blackfeather stock.Bottom picture of the rifle was the wrong one but can't seem to remove it.
First target was 1.220, 1.219, .813, .832, and 1.257. Average 1.068
Second target was 1.048, 1.083, 1.207, .904, and .819. Average 1.012.
