Cartridges above are my current Nickal Wildcats.

Left to Right:

408 Nickal, 8x33 Nickal, 30-25-150, .224 Nickal, .17 Nickal

The 408 Nickal is based on the .458 Win Mag case, with the belt removed and necked down to .408".

The 8x33 Nickal is formed from the .357 Mag pistol case, necked to .320"

The 30-25-150 is a necked up .222 Rimmed case and fires a 150g cast GC bullet.

The .224 Nickal is a slightly shortened .223 case, with the same COL of the .222 Rem.

The .17 Nickal is made from a necked down .310 Greener Cadet case.
