scarter Posted December 26, 2020 Report Share Posted December 26, 2020 Hi there i was wondering if anyone uses one of the specific .17hmr or .22lr vantages with the ranges on the cross hair? If so how accurate are those ranges on the cross hair to real life accuracy? many thanks simon Quote Link to comment Share on other sites More sharing options...
scarecrow243 Posted December 26, 2020 Report Share Posted December 26, 2020 most BDC scopes are used with a certain type of ammo ie head weight speed etc it can be hard to find what rounds were used so its best to try them with your ammo at different ranges to see point of impact hope this helps Quote Link to comment Share on other sites More sharing options...
Walker570 Posted December 26, 2020 Report Share Posted December 26, 2020 I shoot Hawke Airmax scopes on both my 17hmr and 22RF and I know where my hold overs are out to the normal ranges I will be using them. I don't specifically use any of the various cross hair additions. Example my 22RF Browning T Bolt I know shoots about 1 1/2 inch high at 60yrds so tree rat sat nibbling a nut gets just slightly sat on the centre cross hair, now there are occasions I have to shoot at 10yrds and know it will shoot slightly low, so I adjust. The trick basically is to think of what distances you are likely to come across and set the rifle up accordingly on the centre. The 17HMR is a bit more simple because it shoots much flatter and out to 150 on a rabbit requires very little adjustment on hold. PLUS as said above the cartridge/s you are using will make a difference, so find what your rifle enjoys eating and stick with it, don't go shifting choices.

db135 Posted December 26, 2020 Report Share Posted December 26, 2020 I have one on my cz452 22lr I’d say they are accurate there designed for subsonic ammo though. I have mine zeroed at 50m Quote Link to comment Share on other sites More sharing options...

WalkedUp Posted December 27, 2020 Report Share Posted December 27, 2020 The BDC values only work on full mag as the reticle is in the second focal plane. It is a great idea if it was a FFP scope. Quote Link to comment Share on other sites More sharing options...

WalkedUp Posted December 27, 2020 Report Share Posted December 27, 2020 I don’t know I’m sorry, my shooting buddy @worrall26 has one in .22LR and I was going to buy a .17HMR version a few years ago then found out about the magnification always needing to be full. When lamping I wind right down to 4x for as wide a field of view as possible. Quote Link to comment Share on other sites More sharing options...
