22 muzzle velocity free#

The actual weight for an average of 10 bullets pulled and weighed was 26.0gr, so that’s a good start. 22s and hyper velocity! The bullet is very obviously tin from its bright silver colouring and although light is hard to mark with your nails. This bullet is 26gr and achieves a factory velocity figure of 1,650 fps velocity and 157 ft-lb energy. 22 cartridge but using a tin hollow-point bullet. 22 Long Rifle cartridge designed to mimic the profile of a standard lead. Specifications With that in mind let’s take a look at the Winchester Varmint LF. You can see it clearly over the chronograph, with the first string of velocities varying, then steadily increasing and then flattening off with consistent velocities. Have you noticed how changing from one brand to another takes 10 -20 shots to bed in the rifle before accuracy becomes consistent? It’s much like when you clean a rimfire’s bore you always have to shoot it back in again to condition the bore to your ammunition to achieve best accuracy. You also have that age-old problem of ‘conditioning’ the bore when switching ammunition types. The bullets may look the same as a regular lead projectile but you also have problems with lubrication down the bore, which greatly affects fouling, especially build up in the rifling grooves and leads of the chamber area. Even with a sound moderator on your rifle this new lead-free hyper-velocity ammo is going to be noisy. 22 LR, which is the backbone of the sporting or vermin market. But for me, the main disadvantage is that you can no longer have a quiet subsonic. Some may say that’s great – I am sure our American cousins do! But it has a detrimental effect on ballistics, consistent velocities, accuracy and downrange energy retention. This has produced another problem in that the velocity for such a light projectile has increased past 1,500 fps, making it hyper velocity. 22 LR lead-free ammunition has bullet weights between 24 and 26 grains.

22 bullet is nearly half the weight of the original lead version. This, however, is not ideal as it means that for a bullet of the same dimensions – that is, with the necessary length to stabilise in a traditional 1 in 16' rifling – a lead-free.

22 muzzle velocity free#

22 calibre bullet lead free involves using some form of tin or zinc mixture. The trouble is that making a conventional. 22 rimfire lead-free types, this category has really been largely left out.

With all this lead-free centrefire ammunition now being developed and the range of bullet types, calibres and weights being expanded, I find it extraordinary that bar a few. 22 Tin - and his concerns about the future of the.
