How to Fire an Airgun Pellet from a Centrefire Rifle

A comprehensive look at the velocities obtained by fitting a centrefire cartridge with an airgun pellet and using a primer as the sole propellant source.

The .17 Rem. is underbored, but you can load a pellet by pushing it up through the primer hole forming it down and seating it in the neck with a nail.

The velocity figures in the table are the average of 5 shots with the exception of the .357 and the small/large rifle primers which was the average of 2 as they couldn't be easily reloaded in the field like the others.

<p>Uh... wouldn't this destroy the skirt? Also, just do a me a really quick favor and try putting some WD-40 in the skirt. Then cover with something waterproof. It may cause a very low power detonation like in a piston airgun when it achieves a boosted dieseling. It will probaly help with power a bunch. </p>
Love it, Love it, Love it. <br>Wondering if I can use a 22.250 or .223? Would try it myself, but don't have one, but am looking at buying one or the other. <br> <br>Also, wondering about accuracy. Have you done any tests? I know my pellet rifle likes some pellets and not others . <br>Thanks and Regards
so...similar speeds and impacts to a high end air rifle, but with all the legal requirements of a gunpowder firearm? <br> <br> <br>If you plan on doing a fair number of these shells as conversions, consider getting a handy-dandy Hornady Primer Pocket Reamer Tool. and instead of drilling out the origional spent primer, just press it out from the inside?
In Australia the legal requirements for airguns and centrefires are little different and high end airguns are expensive. Its just an expediant way of using one gun for two very different tasks. <br> <br>The spent primers were removed with a reloading press, not drilled. The spent shotgun primers in the modified cases are just knocked out with a nail and reloaded in the field.
