But TBH SHV I'd be taking your 527 carbine on hunting trips over this rifle; 7.62x39 hunting loads hit like a 30/30, PLENTY heavy enough the vast majority of Aussie game, and you'll really appreciate its portability once you starting walking around with a rifle. That's a fantastic little rifle for so many reasons.

sounds good in theory, but your 7.62x39 will tick all those boxes and then some. I doubt you'll be taking shots past 200m in the field; 7.62x39 is perfectly capable of precise 200m shots. pig hunting; hot 7.62x39 hollow points will easily break down a pig. plinking; you can shoot Trail Boss cast-lead loads through your 7.62x39.

In case you hadn't noticed :P I'm a big advocate of 100% familiarising yourself with the ergonomics and trajectory of a single load and rifle, and the only way to do that is to get some serious time behind the trigger on that specific load and rifle. Chopping and changing is novel, but it won't do you any favours when it comes to precisely honing your hunting and offhand capabilities.

I'm only referring to the practicalities of hunting here though; don't get me wrong I love owning and shooting all kinds of loads and guns at the range, and you have every right to own and play with as many loads and guns as you want. But if you wanna git guud (at hunting) I say KISS and practice on the one gun.

And to support my claims, watch Hickok standing offhand your exact cz527 out to 230 yards with iron sights! https://www.youtube.com/watch?v=caCiANMCixo :D :D :D :D they shoot pretty flat so not really any argument for the 308w, long range F-class style demands a target rifle anyway, not a sporter barrel rifle .

tried 2 x 5 shot groups, cold barrel and hot barrel, 168gr zmax, 42.4gr 8208 50 meter indoor shooting range(St Mary's)

cold barrel 5 shoot got one fly(it could be my fault), otherwise not too bad

hot barrel one is ok, for hunting should be good enough anyway...

Now you just need to sight in for max point blank range and off you go!
About 1" high at 100yd is common.

To be honest, a lot of blokes severely limit the useful "point blank range" of their rifles by zeroing at too short a range.
A .308 Wichester, with the load you are using, would be better sighted for a 200yard zero.
Now before all of the squeals about that being "too far" for a hunting rifle, and "I never shoot anything past 150", let me explain.
A 200yd zero will have the bullet printing about 1' high @ 50, 2.3" high @ 100, 2" high @ 150, spot on @ 200, 3.7" low @ 250 and 9.4" low @ 300Yds.
So, any "game" between 0 and 250 yards, ( your effective PBR ), you just aim in the middle of the boiler room and it will be a kill shot, ( if you do your bit of coarse).
You also have the ability to take a reliable shot at game out to 300 because a back-line hold will still drop into the desired target area. NO HOLD-OVER.
That same rifle zeroed @ 100yards will print POA @ 50, POA @ 100, 1.5" LOW @ 150, 4.6" LOW @ 200, 9.6" LOW @ 250 and 16.6" LOW @ 300yards.
You effectively loose 50 yards of PBR and get into hold-over territory @ 250. Cheers, :drinks:

Yep, both my 30-06 & 223 are 1" high at 50.
Good to go out to about 250.
Interesting to note that most popular hunting centerfires (I know this is a general statement so don't be too critical ) set at 1" high at 50 will be good out to at least 200. (give or take 2")
Many have a similar trajectory assuming the projectiles are spire design.
Hunt safe, look after the bush & plug more pests. :thumbsup: Better to load on the mild side. :o The greatest invention in the history of man is beer. :drinks: "Often the written message doesn't convey all of the information"

I run my 22-250 at 1.5'' high @ 100yds and aim slightly above the middle of what i'm shooting at and i am getting around 350yds comfortably
My 25-06 i zero at 100yds because its got a etched reticle with ballistic markings so for me i don't need to zero 1'' high scope is good out to 800yds
but i'm still working my way up to 800yds, i run out of paddock at 450yds awhile back and haven't got back to it
Also something i've noticed is that when i had the plex reticle on both rifles they shot pretty much the same as far as drop goes with 1.5'' high @100yds
out to 350yds, this was a bit of an eye opener for me

My post was directed at the ballistics of the .308 Win load that SHV is working with.
Ballistics of other chamberings will of coarse vary, but the same basic principle applies, the shorter the range that you zero for, the shorter your maximum PBR.
With your ballistic reticle, you are basically sighting it higher at 100 by the change in cross-hair you use. This in turn is extending your PBR. An interesting exercise would be to put it on paper @ 100yds using each different marking. This will tell how much higher each increment actually is. A quick look at a ballistic calculator will then give you your zero range for each one. :thumbsup:

OK mate will try that it's all good fun
It's all a little bit more to try and can be put it in the old noggin for a later date
I have set the ballistic reticle to a calculator but haven't actually put both rifles on paper side by side which could be interesting as you said
I'll try it and see how it goes

Thanks Cheers

looks like 42.4 is also good for TFB 150gr projectile
