tungsten Posted April 24, 2009 Report Share Posted April 24, 2009 After many years of shotgun shooting I have recently included a .22lr CZ to my cabinet. Using Eley/Winchster hollow points I have zeroed it in on a range at ~90yds (fixed unfortunately). What gain might I expect on the target at 50yds, say? Does anyone use CCI shorts?

Dunkield Posted April 24, 2009 Report Share Posted April 24, 2009 Unless all or most of your shooting is at that range, I would look to re-zero at 50 or 60 yards, and then hold over for the longer shots. I use Winchester's for all my hunting and Lapua solid nose for plinking Quote Link to comment Share on other sites More sharing options...
Justintime Posted April 24, 2009 Report Share Posted April 24, 2009 Ely do subs they also do practice rounds that dont change your zero once zeroed for the hunting rounds Quote Link to comment Share on other sites More sharing options...
wymberley Posted April 24, 2009 Report Share Posted April 24, 2009 Hi, The answer is approximately 2.6". However, it's best to listen to Stuartp. Quote Link to comment Share on other sites More sharing options...

tungsten Posted April 24, 2009 Author Report Share Posted April 24, 2009 (edited) Thank you. The intention is to zero at 50-60yds, but unfortunately at the moment I only have access to a range with fixed firing point at ~90yds Edited April 25, 2009 by tungsten Quote Link to comment Share on other sites More sharing options...
Dunkield Posted April 24, 2009 Report Share Posted April 24, 2009 From that link if you zero 6" low at 90 yards, you should be there or there abouts for 50 yards? Quote Link to comment Share on other sites More sharing options...
wymberley Posted April 24, 2009 Report Share Posted April 24, 2009 Hi, Tungsten, Two things to bear in mind: We're talking rimfire here so it's not possible to be pedantic. Unless you've won the lottery you probably won't be using the quality of scope whereby you can rely on the accuracy of the clicks. At best they will just be an indication of what to expect. You haven't mentioned what rounds you are firing - sub-sonic or whatever? If you post that info, I'll try to help. Quote Link to comment Share on other sites More sharing options...
MC Posted April 24, 2009 Report Share Posted April 24, 2009 If it helps at all if you zero at 50M you will be about 7" low at 100 yards. A 15 yard zero is about there for a 50M shot. Sorry to mix between yards and metres but this is practical knowledge through target shooting. And they are the official ranges shot.

Dunkield Posted April 24, 2009 Report Share Posted April 24, 2009 another thing you can do Assuming the range you have access to you can't walk forward 40 yards and shoot from there Get there early and stick your target up at 50 yards before everyone else starts shooting? Disclaimer I would just like to say I have never ever done this at Bisley Quote Link to comment Share on other sites More sharing options...
Ozzy Fudd Posted April 24, 2009 Report Share Posted April 24, 2009 have you not got any land you could zero it in on? i dont have access to a range anymore but the permissions i shoot on have no problem with me going out and blatting a few targets to zero in Quote Link to comment Share on other sites More sharing options...

I went to the range today and grouping quite well with Winchester subs. I put an old credit card (as I thought) on the target and hit a 3 shoot group (~90yds), unfortunately when I looked after shooting the group, it turned out to be my wifes card she asked me to look after!!

wymberley Posted April 24, 2009 Report Share Posted April 24, 2009 OK, Tungsten, My 2.6" was for Winch sub, as is the following. Two ways to do it, so we can cross check for accuracy. 2.6" high at 50 at which range your click effect is halved. 2.6 divided by 0.125 = 20.8, ie, come down 21. Zero at 50 is -4.8 at 90 so you need to come down that much. Click effect here is 90% or 0.225. 4.8 divided by .225 = 21.3r, ie, come down 21. Job done but please bear in mind the previous remarks about rimfire and scopes. Now you're in trouble, you may as well turn it around and have another go.

fallowbuck Posted April 24, 2009 Report Share Posted April 24, 2009 I zero at 50 yards and if I want to shoot something at 100 yds I hold over by lining up the thick post tip at the centre , rather than the centre of the reticule cross. This is of course a duplex reticule or 30/30 as our American cousins call it. Works for me. Quote Link to comment Share on other sites More sharing options...
tungsten Posted April 25, 2009 Author Report Share Posted April 25, 2009 Don't know if any one else has an Iphone? But you can download to the phone a ballistic calculator, There are several on the Iphone but this seemed the best, I just typed in "bullet" then I tried "ballistic" in the Apps search. Ballistic v1.8.0, £3.99. It,s quite good and confirms Wymberley's calculations to within 2 clicks.

Have had a look at the site which yours refers you to and that indicates that yours may include the BC for rimfire rounds. Would be a bit surprised if it does, but could you let me know?

Have had a look at the site which yours refers you to and that indicates that yours may include the BC for rimfire rounds. Would be a bit surprised if it does, but could you let me know? There are quite a few bits and pieces come with this software; one is a list manufactures ammo specs. There is only one for .22, think it's a generic spec and it show the .22 BC to be 0.104. Still playing around with it but I am impressed as you can set your own loads as a favourite, save range visits, target info, zeroing info it even a the press of a button factors in weather conditions and altitude for your current location B) Quote Link to comment Share on other sites More sharing options...
wymberley Posted April 25, 2009 Report Share Posted April 25, 2009 Thanks, Tungsten. Didn't think it would be comprehensive. They seem to keep that info close to their chests, probably the fact that we can't reload means we don't need to know. Cheers Quote Link to comment Share on other sites More sharing options...
Goldfish Posted April 27, 2009 Report Share Posted April 27, 2009 Question in first post: I use CCI shorts. Good for 50meters. Quieter than subs. 29 grain heads Equivalent to an FAC air rifle Great for barns/woodlands and picking off sitters in rookeries. Quote Link to comment Share on other sites More sharing options...

Beardo Posted April 27, 2009 Report Share Posted April 27, 2009 are you using the CCI CB Shorts? just been looking and they also make a low power short in a long case for better feeding... last section down the bottom of the page http://www.cci-ammunition.com/ballistics/rimfire.aspx "CBs are reduced-power cartridges for low-noise pest control or practice. Both are loaded to the same velocity; the CB Long makes loading in some firearms easier. 22 Short CB part #0026 22 CB Long part #0038 Not designed to cycle semi-auto firearms. " they sounds perfect for something i have in mind (don't have a FAC airgun, and the rimmies are a bit too powerful) Quote Link to comment Share on other sites More sharing options...
wymberley Posted April 27, 2009 Report Share Posted April 27, 2009 Nickbeardo, Hi. Thanks for the CCI website, but sod it! Until they changed the spec., Federal 50 gr were ideal in my 22 WMR and since then I,ve had to use WRS and/or Remmington which are pricey, particularly the RWS, because they are the most accurate. Ran the programme on the CCI 30gr V Max which are specified on their site and they look a bit tasty. Spoke to GMK and they don.t import them - will if my local dealer will order 2000. Fat chance! Good news is, Tungsten, they do import the CB long (0038). Quote Link to comment Share on other sites More sharing options...
Beardo Posted April 27, 2009 Report Share Posted April 27, 2009 i shall have to get me some of those CB longs... Quote Link to comment Share on other sites More sharing options...
