hi all I'm looking for info on Norinco M14-S groupings, what kind of groups both factory & reloading are you guys getting from this Norinco & Polytec m305s

lets say 100 & 200 yards

also not on topic what the overall weight of a M14s 18.5" with & without a scope.
 
I've gotten enough 4-5" groupings prone at 200yds with my M14S from the prone position to know that it's at least that accurate. I usually average a bit larger, say about 6-8."

Sitting and with shooting sticks, I probably average around the outer edge of the groupings described above.

At 100 I practice shooting freehand, which is pretty much guaranteed to hit paper, but the grouping varies widely depending on how I'm feeling on any given day.

I've achieved the above with both an unmodified, chinese wood model, as well as after I've put in an NM oprod guide and a USGI stock. If I get the same accuracy and similar POI with soft points as I do with the copper washed Norinco, I'll be satisfied enough to hunt deer with it.

Edited to add: I shoot regular sighting in targets at 100 and figure 11s at 200 yards.

I've shimmed my gas system, a mod that is not free but almost. Shims are dirt cheap once you find them. Most, if not all, mechanical workshops have them in an assortment of sizes. The last set I used I got for free. Google for a youtube video with instructions.

With that mod and a Nikon 6x scope in a Bassett mount I've gotten several three shot groups with all holes touching @ 80 m=87 yards. I'm no expert shot and my wish is to keep the groups beneath 2"@ 100 m, so I haven't done any more testing to see exactly where in the sub 2 MOA spectrum my rifle is, I've just noticed that it's good enough by a decent margin and that's it. Before I understood how important it is to torque the gas plug properly I the gun regularly shot 1.5" groups @ the same range. Since I torqued the gas plug properly I got the "several groups with holes touching" improvement described above.

The shooting done for testing is done with all the cheats I can think of. Forward support, support beneath the buttstock, proper breathing, a target that goes well with my reticle et.c. The idea was to test the rifle, not me.

I shoot handloads using Norma Brass and 44.0 grains of norma 203b powder. The 203b is supposedly similar to RL-15. The bullet I use is the 165 gr BTSP Interlock from Hornady.

I leave no guarantee that my load is safe, I made that assessment but I might be wrong.

My gun kills deer and hogs just fine. Currently testing lethality on moose and jackrabbit :D
 
I seem to average 2 inch, five shot groups with the Norinco ammunition I got with the deal from CanAm on a short M305. Shot the same ammunition through my TRG22 for comparison and 5 shot group sizes were about the same but usually 3 or 4 shots touching and 1 shot opening up the group. That would be at 100 yards.

I'm thinking of batching the rounds by weight to see if I can get better consistency - The short M305 is more accurate than I had hoped and the Norinco ammo is better than I expected

If you check my profile I'm pretty sure you'll find a pretty informative thread on my experiences with the gas plug.

There is a wide range of appropriate torque but you're supposed to torque it much harder than I had done. I used a wrench and a bathroom scale to torque it within spec but I think you'll be fine just taking a wrench and torque it well and you'll be fine. Just don't ruin the threads or you'll be sorry.
