    A good .257 barreled airgun with 257420 or 257388 bullets will shoot one hole groups at 100M. Wind drift is about one fourth of a pellet wind drift. Yes, they do use more air but shooting at 100M or beyond with pellets is quite hopeless in windy conditions. .224 as an airgun caliber is also gaining in popularity, it is actually a bit more accurate than a .22lr as you can use bullets with better BC and have the ES in single digits which is not achievable with .22lr ammo. Bullets are the future of long range airgunning, people are shooting (and hitting) soda cans at 300M with airguns nowadays.

    As soon as these are available in .177 and .22 I will be happy to try them.
    My concern is that if they need more air to push them, then running them at a reasonable power would leave the gun overpowered with diabolo pellets.
    Good deals with these members

    You should note that airgun barrel twist rates are in general not well matched for shooting bullets. In .22 and .25 with 16-18" twist rates medium length or short bullets work, in .177 they do not stabilize. As an example my .224 has 12.7" twist barrel and my .257 uses 14" twist. However, if you want small caliber stuff people have been building .172 bullet shooting airguns using powder burner barrels with good success. It might actually be rather interesting to see a 12 fpe .172 shooting this bullet:

    I already have .224, .257, .357 and .45 bullet shooters, no need for a .172. In practice it's no more efficient than a .224 and bullets have worse BC. For low power levels it would have an edge though.

    I don’t believe that wind drift is 1/4th of the pellet with side wind, you would have to have 4x the energy to achieve that. Slugs drift less but by not much better, not even half.

    If you don't believe it do the math, try it in a Chairgun or test it IRL. .22 pellets are around 0.03-0.035 in BC while .224 bullets are in 0.110-0.140 range. .25 is around 0.035-0.040 against 0.140-0.190 with .257 bullets. Reading this thread might also help And yes, I've been competing bullet shooters with my .25 pellet gun at 100M BR and it is a very tough job to keep up.

    That .172 air is impressive , hits with a right old whack

    They will when you shoot about 30 slugs and the hole will be minimum 3/4 inch big.
    A coke can measures a bit more than 2.5 inch in width.

    The only airgun which can do that is the daystate redwolf 10mm groups at a 100 with 10 shots even if they're not slugs that's impressive.

    At the risk of pretending to be ballisticboy, I must point out that BC changes with velocity.

    But your general point is right. Waisted pellets were designed for smooth barrels at low velocities. Then rifled barrels made them more accurate. Amazingly so (indoor 10M match, for example) at close ranges. But they and their associated barrels were historically made for 10-25 metres, without much regard for either retained energy or longer range accuracy.

    If airguns had never existed, we would probably now, in ineventing them, at 12ft-lbs, go for a bullet-shaped projectile in 4-5mm or so diameter, optimised (with associated rifling twist) for accuracy to 50M.

    I've found this information interesting as I'd never come across using slugs, or 'bullets' in an air rifle before this thread

    Be interesting to see if anyone made them going forward and if there were any advantages for 12ftlb air rifles

    It might be an interesting direction to take non- lead pellets in. In diablo form results seem to be mixed at best in terms of accuracy and generally poorer for energy retention due to lower densities. Going down the bullet route could be a game changer.

    At 12 ftlb they would get stuck in the barrel or just fall out of the muzzle.

    That 26 grain .172 bullet cast from tin would weight about 16 grains. There are 22 grain molds as well which would make 14 grain tin bullets.
    That would be 570 fps and 620 fps for 12 fpe, it should actually work quite well.

    i have some nielson 19 grn .22 slugs on there way to me .i'll be using 35 ft lbs daystate wolf and testing out to 100 yards or more if they are good.last time i took the 18.1 grn jsb pellets out that far they grouped about 1.2" at 80 yards but opened up at 100 even in still conditions.95% landed in 2.5" but the smallest of breezes (un detectable ) or flyers meant real groups where more like 4 ". using 18.1 jsb i'll rabbit head shoot to 60 yards and take pigeons to 80 but after that there would have to be luck involved and that is for paper punching.i'll giving an honest opinion on the 19 grn slugs asap.
