Help in the wind a little and whack a fox should you bump in one.
#SUBSONIC VS SUPERSONIC CRACK#
Whilst we think subs are quiet to a bunny they are not! In my experience an experienced rabbit colony will hear the muffled pop, a hissing bullet, an impact and draw a line straight to you.then they are gone the opposite way!.Ī sonic crack often confuses for a second shot.Ī good hv will flatten your traj some assisting any range error. I like hv rounds.and they dont always use a lighter bullet! The ability to stay on a rabbits head from 30-115 yards with a single set zero on trajectory is what the HMR is all about
A HMR just has a flatter trajectory and the ability to be comfortably supersonic through all its usual range window. 22 LR with subsonic is already a match for the HMR at 100 yards (windages are near enough the same) you just need to account for the trajectory drop (6-8 MOA) at 100yards from a zero around 50 yards. In the eyes of many (myself included) a good.
in winds you wont be able to call without flags. As much as 3" might be the best for less favoured HV or if you were getting a bit of wind that day using high grade ones as the light HV bullet really does suffer its effect worse than the sub. On a good day without any group spoiling winds I shouldn't expect better than 1 1/2" with the very best HV and yet I should expect good subsonic to place inside 1", sure you might get a group better than 1 1/2" but I should look at that more as fluke if you put enough rounds down range with the LR subs you will also get some even more impressive little fleas bum clusters. If you also add increased windages its appreciably less accurate at 100 yards than a good sub. If you read my post above I mention the transonic zone, what this is the point the supersonic comes back towards the sound barrier it has a de-stabilising effect on any bullet and it is expected to occur at just before 100 yards with the. If they were accurate they'd be worth it surely notwithstanding the noise? OK so you're paying 18p a round but that is still cheaper than an HMR (yet they are only SG cartridge prices). They may be round nosed but they'll still hurt. Just out of interest where do match grade rounds with supersonic velocities fit into the accuracy picture? Things like Lapua Midas + or RWS R100? They must be stable out to beyond 100yds for some disciplines. I did a fair bit of HV testing last summer and didn't find any that could do better than 1 1/2 " at 100 yards and most were double that in totally great conditions ( I recon on 3/4 -1 1/2" with all subs in my gun except Remington as the norm) Even the WMR and HMR don't offer a great deal more in practical terms. 22 rounds its always better to consider a small centrefire. Personally I feel once you get over subs and std velocity. Accuraccy again normally suffers as the lighter bullet is less suited to the barrel and yes the bullet enters the destabilising effect of the transonic zone (normally around 100 yards give or take)They are also noisy little blighters by comparisom to the practically silent sub.Īdvantages, they often cycle better in certain semi -auto guns and are worth considering in terms of the extra energy (near double depending which you compare) if you have say a lot of larger than normal rimfire quarry to deal with, thinking in terms of lots of hares damaging crop or hedges etc. This means the bullet although faster / flatter and harder hitting is more subject to wind drift than a slower heavier higher BC subsonic round. Hi- velocity rounds use a lighter bullet to achieve the speed within given pressure limits.
