Northern BC, Coastal BC, or Africa. Depends on the
I'll be testing this personally in a month or two hopefully when I get a ARMS #18 to mount a scope, but I'd like to hear from others. I know Hungry, Skullboy, GGFB, Lazerus2000, and mysticplayer are all very experienced with the M305 among others and hopefully will be able to give me an idea. Here's what's going on; I'm building an M305, and I've gone to a lapped in TRW bolt and USGI fiberglass stock along with other smaller mods. What I'd like to avoid is a USGI barrel, simply because of the work involved, and secondly the $ involved (also using a metric barrel accessory, like to keep it that way). Have you found Norinco barrels to deliver acceptable accuracy? (I'm hoping to hold 2 MOA or less, 1.5 would be great, getting tighter than that is what the bolt guns are for IMO)

Thanks!
 
I get 1 minute of angle

Only modification is a piece of sponge duct taped on. So yes the barrel can be decent. 1 MOA at 200 yards
 
Don't know that Norinco barrels shoot any worse than USGI barrels. Unless you want to go to the time and trouble, solely for the sake of changing the barrel, I'd carefully shoot it first, before making any decision.
 
I think your goals are quite realistic and attainable with the stock barrel.

edit to add: I've never had a scope mount that holds zero so haven't been able to test mine out properly. With irons I had great groups at 50 yards (my eyes aren't good much past there with irons) that were definitely averaging within 1.5 MOA using portugese milsurp. I've done some small improvements since then, so I imagine it will shoot 1.5 MOA with a scope on it.

This is with a USGI stock, all original parts including bolt, with the exception of a rooster spring guide and usgi springs in the oprod and bolt. The barrel was shortened by ATR so the crown may possibly be better than the norinco factory, not sure about that.
 
I am getting gust under 1 MOA with mine at a 100 with port amo
I am using a bushnell 3200 10x40
the only mod I have done is got rid of the wood stock and whent
with a GI sinthetic
 
Ardent, my last personal rifle shot sub MOA out to 180yds. Pic attached.

All Norinco metal, laminated stock bedded front and rear (although orig mystery wood stock works fine too), shimmed gas system, tuned trigger, and tuned handloads. Scope mount was a SA Gen 3 clone, Elite 4000 2.5X10 in Burris rings. Added a Rooster33 check rest and spring guide just for kicks.

They are very finicky to load for and found that 2 to 3 tenths makes a difference in group size. I was using 155gr AMax and Benchmark lit with a Fed 210M primer in collet neck sized fireformed win brass. You can also use WCC 845 and H335 but will have to adjust for changing temp.

The M305's I have worked on all shot MOA or very close to it. They have very well cut chambers. I see no point in changing to a USGI barrel. Maybe a Douglas or Kreiger if you really want small groups.

i get good groupings with my stock m-305 i got a scope but thats it and i can get 1-2" groups at 150 yards i can hit a 1L bottle of water at 150 from prone every time.
talk to ya all later

The Norinco crome lined barrel and the real gi ones will out last 2 or 3 commercial barrels, if that matters to anyone.

Anyone trying to shoot small groups with the Bushnell 10x mil dot scope will probably fine their 200m groups better than the 100m groups, due to the paralax being set at close to 200 yards.
 
group

i got an 11 in group at 500 with my norc with mil srup ammo (no scope) that was a good day the group was 11in high and was only 1 in from side to side. also when i put my gun together the head space was so short that i could not get ammo to fit now a go gage just fits. note that i bought minr as a kit not assembled just a box of parts so i hand fitted all parts to minmum spec and less
 
In the main, Norinco barrels are equivilant to their USGI counterparts.

I got MOA or better out of my Norc barrel (before I replaced it) with some careful load tuning.

SKBY.
 
My bone stock one shoots sub 2" with Lake City match for 5 shots at 100 yrds. Even with open sights those beer cans better keep their heads down.
