roger Posted August 1, 2008 Report Share Posted August 1, 2008 (edited) Hi all, Does anyone know what S.Yorks and Derbyshires policy is on land cleared for .17HMR. S.Yorks say that land cleared for .22RF is not cleared for HMR. Is this common to other areas, Thanks, Roger Edited August 1, 2008 by roger Quote Link to comment Share on other sites More sharing options...
mr lee Posted August 1, 2008 Report Share Posted August 1, 2008 We had our main shoot cleared for both no problem but the size of it at 3000 acres is no suprise. Our golf club shoot is only cleared for .22 rimmie though. W Yorkshire. Quote Link to comment Share on other sites More sharing options...
Dave-G Posted August 1, 2008 Report Share Posted August 1, 2008 Despite being a faster bullet the 17HMR is a smaller calibre and lighter projectile so it should be cleared for anything up to .22LR (if indeed it was restricted to LR - any .22 RF is the norm I think) However the HMR is still relatively new in terms of home office advisories and some forces interpret things differently. Most "townie" places will have a shock and horror policy where shooters are thought of as rare freaks to be put off, while country areas will will just be a formality.

casts_by_fly Posted August 1, 2008 Report Share Posted August 1, 2008 dave, On the other hand it is going a lot faster and has a lot more energy than a standard 22LR. I think the classification scheme should be air rifle, rimfire, centerfire, but we've been over that here many times before. thanks rick Quote Link to comment Share on other sites More sharing options...

For that reason I'd say it's safer by far - and having a flatter trajectory it's less likely to miss quarry with regard to poor range estimation. I'd agree with your classification suggestion - albeit a tad over simplified for the CF. Quote Link to comment Share on other sites More sharing options...
casts_by_fly Posted August 2, 2008 Report Share Posted August 2, 2008 Hi Dave, Yes, a standard velocity 22 catches up tot he HMR in energy (or rather the HMR drops off faster than the 22) out a little past 200 yd. So yes, in terms of a missed target or a riccochet you're right for sure. I don't think that I am over simpified for the centerfire though. About the only 'exceptions' that I would even consider would be on the low end and would be a 22 hornet. Anything else that would be even close to an exception is too odd to bother with writing into the rules (like a 17 AH or Mach IV). Otherwise, the main criteria for clearing land for a given cartridge is to ensure that there are safe backstops to shoot against. While a 222 and 40 gr bullet will need a little bit less of a backstop than a 300 win mag and 180's, in practical terms we're not using dirt piles as our back stops. You're using a hillside or the ground (with you above shooting down). In practical terms, if it is a safe backstop, it will stop a lot more than anything that we are likely to be shooting.
