Colt 1911 Series 70.
My first 1911 in 9mm.I loaded up some 147grn rounds and it biffed them through the target sideways.Hope things improve with the 115 and 124grn projectiles I bought.
Its no Sig P210,but the fit and finnish is pretty good.Attachment 69088
I would say it's complete. Very nice rifle
na need some tactiwank shit on it :thumbsup:
This gun a is a shitter.
I have tried five different brands of Bullets,the bore looks really nice.I wonder if the Bushing is playing up or there is a nick in the crown.The only pistols that I have used that were more shit were a "Helwyn" Egyiptian copy of a Berretta and a Marakov that had probably been in a fire and then eaten by a Camel .
Try increasing your velocity. They may not be stabilizing. If you're using lead then try stepping up to .356/57/58 and see if one of those works.
Thank youQuote:

Fiocchi 115 and 124 grn Factory fodder,124 grn Geko,124 grn Sellior and Bellot all of that was factory stuff. There are no groups,just patterns and all of those brands apart from my reloads were fired from a Randsom Rest.
I think I will try and recrown it,if no joy there I think I will get a new barrel.
Just buy a CZ and it'll work with all that ammo. :)Quote:

I reckon your gun is just fine, try stepping up bullet diameter or velocity or maybe you are putting too much crimp on your loads. Lots of info if you search and it keeps coming back to the same set of circumstances for what could be causing your problem.
CZ Shadow 2 - 147 gr tumbling - 9mm/38 Caliber - Brian Enos's Forums... Maku mozo!

I guess all the factory stuff stuff was too. Fiocchi dosn't have a great name for accuracy,it groups ok in my Sig but with Geco its literally a one hole shooter.Sellior and Bellot and Geco are about equal in quality and price,its what alot of shooters are using here.
My mate is bringing some Speer cartridges and some Nato Ball.
We have removed the human error with the Randsome rest,but for not getting any groups and with a spread of about 12" with everything tried its the gun thats playing up.Looks like the crown is dinged as the fingers on the bush look good and everything else looks ok.
Being produced in the 1970's it was likely made with pretty mild 124grn cartidges in mind.

I shoot 200 gr cast bullets in my .40
I can reach power factor at 4.4 grns of N320.
I had to speed them up by .2 because I had 1 in 20 nearly keyhole. First thing I thought of was velocity. (Possible variation in powder thrown in progressive press)
I haven't had a problem since I went to 4.6 grns.
It does seem a bit odd factory ammo especially Geco, is not performing as they generally reach PF for given projectile weight in my experience.
I would try speeding your load up with a deeper seat depth first and if that doesn't work change powder.

Thank you for your advise.
I cleaned up the crown with a large Brass screw and some coarse,then fine grinding paste.Cleaned it up and went straight to a competition.
We were shooting feltstevne (feild competition) https://www.youtube.com/watch?v=oTsngdvfexc
Didn't get one key hole,with either 147grn or 124.I did pretty well considering,I havn't had the chance to see if its still biffing bullets around but only another go in the Randsom rest will really tell.Worst case its a new barrel for $214 USD and I can live with that.
I have loaded up a few rounds at 4.1 grains of N340,thats max,so we will see how they go.
