Re: CZ 750?
I have been shooting a CZ750 for just over a year now. I bought one because I needed a rapid firing 400 to 1000 yard precision rifle. And couldn't afford one...
I have found the CZ750 to be tempestuous, misunderstood and superb. I have tried everything to make the purchase of this rifle worth the £1,800 (second hand) I paid for it. I was initially disappointed because I had a pretty basic scope on it and was using ex-mil ammo. I have now found the ingredient. A decent scope. The accuracy of it with handloads is excellent. I have put an IOR 4-14X50 scope with IOR heavy rings on. The crystal clarity of this scope has made all the difference to the shootability of this rifle. It is a heavy piece of kit. No doubt. It (like all precision rifles) needs a good scope to maximise it's performance.
I shoot mainly 'practical rifle' at Bisley and MOD ranges in Southern England. Details are 10 rounds (plus sighters) fired at scored 12, 12C, 11 and 14 targets under time pressures varying from 45 to 120 seconds.
I have now put more than 2000 rounds through the rifle and am delighted with the performance of it. My first 600 rounds were a mixture of anxiety, disappointment and ecstasy. There is not much I can't hit with it. I'm not saying it's perfect. It is currently in with my gunsmith having a bigger bolt knob,20MOA scope rail and HK sling swivel loops put in the rear stock. I am also getting them to crisp up the trigger. My gunsmith is ARMALON UK. I have other rifles of his so I know he does a good job. CZ trigger is a bit mushy out of the box for hardcore shooters like my current club members...
I have experienced superb accuracy with:
168 SMK's, Lapua brass, CCI primers, 43.5 grains of VVN-140(about 2600fps)
175 SMK's, Lapua Brass, CCI primers, 42.5 grains of VVN-140 (about 2500fps)
155 SMK's, Lapua Brass, CCI primers, 44.5 grains of VVN-140 (about 2800fps)
But the key is the 175SMK. Just load so it suits your rifle in the temperature you are shooting in. 43 gr VVN-140 or similar should do it. I know this is above the loading manual data so work up in increments. And understand where the data is being published...
Just to update anybody interested in a CZ750. I have been working up my loads and have found that 44 grains of VN140 or 45 grains of Varget are producing outstanding accuacy in this gun. (175 grain SMK's) I am gettting 0.6 inches at 100 yards and 0.8 minutes (2.6 inches) out to 300 yards. These rather hot loads are proving very accurate out to 1000 yards and the heavy barrel of the 750 will cope with 20 round details without losing accuracy due to heat. I have reloaded the brass 5 times now and there is no sign of pressure so far. 2.80 COAL.
For shorter matches I have taken to using 42 Grains of VN140 with 168 SMK's. A beautiful load. 0.3 of an inch at 100.
The more I shoot this gun the more respect I get for it. They are not very popular and they are condemned for being industrial, heavy and clunky. I have now put 3000 rounds through it and NEVER had a jam or a misfire.
Not much data available for the CZ750. I must confess to liking this rifle very much. LONG LIVE IT!!!
