The 22-250 went the way of many others before it but I did actually use those 55s and still have about 40 odd loaded rounds as had a nice mild round that shot awesome with them so they might come back into circulation again if another 22-250 comes my way..

So since I didn’t actually get any pressure when working up a load the other day curiosity got the better of me today and I decided to keep working up and see if I could find another node. Got to 46.8gr superformance and again the groups tightened right up. Loaded some more to chronograph and shot two more sub half inch groups and getting 3290fps. 47.5 gave a sticky bolt and the groups were opening up again anyhow so have settled on the 46.8gr load. I’ll check the load again when summer approaches to ensure any temp sensitivity issues won’t cause problems, I know the superformance can get a bit upset at opposite ends of the mercury. Very impressed from a short barrel and looks like the load will pack a good punch a fair way out. I’ve been doing a bit of research on the yank forums and they reckon this projectile needs about 2000fps and above impact velocity to open reliably in deer sized game which it certainly holds a fair way out. I’ve searched high and low trying to find a z3 3-10 with BRX/BRH reticle to no avail as I really love these scopes super lightweight and great glass and performance, nice forgiving eye box and balance well on lightweight rifles. So I decided to make up a turret label and dial it a few times to check return to zero etc and it passed with flying colours couple of first round hits at 380yds and 530yds, if I’ve got time to dial then I’ve got time to take the cap off and do it so I’m very happy with it and think that me and the wee rat gun will get along just fine.

Bloody good idea they are a bloody nice little scope.

+1 @Ryan_Songhurst what did you use to make the label?

Word of advice, if you think your gonna be dialing take the cap off and leave it at home or in a safe zip pocket/pouch....dont ask me how I know

@Dreamer I used this website https://turretlabels.com/ I had to do a bit of trial and error to get the size exactly correct but I’ve got it sorted now. Where it asks for your turret diameter you need to add 0.2mm more to allow for the slight overlap of the paper when you wrap it around. The z3 turret has a diameter of 17.8mm and a label setup for an 18mm turret is perfect. You have to sign up for an account but there’s no requirements other than entering your email and choosing a password, I just used a burner email account I have as I know these sorts of things usually result in ads etc being sent your way but the website itself is easy as to use and heaps of options for customising and adding extra rotations etc I just went basic

@Ryan_Songhurst thanks mate!

Also, @Dreamer I made a bit of a stuff up on that label pictured as for some reason I thought that the z3 had 64 clicks for a full rotation giving a total of 16moa on one rotation (back to zero being 16moa) but it actually has 60 clicks so 15 MOA, have reprinted and all clicks line up perfect with hash marks now

What ballistic program is that mate? Bloody potent load that’s like .260 143 eldx sort of power out far

Weta Precision

You might need to select g1 bc mate weta defaults to g7 the numbers seem incredible for the humble .243 if you enter g1 .333 it seems more realistic be a shame to have a cock up in the field . If all is correct that’s bloody impressive well done

It’s set in G1 .333

Weird I get that data if it’s g7 g1 changes it drastically either way shit hot man sharp shooting to!

Actually just had a look at it again and you’re right, it’s showing different numbers between the solution it gives and what’s on that table. Seems to dial all good but I’d say that table is using the wrong bc function. Oh well, not as super duper as I originally thought but still capable 350yd load which is what I want the rifle for anyhow
