My Winder musket is the piece that keeps me constantly on the lookout for .22 Short ammo! A real pleasure to shoot.

From a collector standpoint rechambering for .22 LR is a bad idea. From a shooter standpoint you might be disappointed by the accuracy (or lack thereof), which is due to the inherent differences between .22 Short (29gr. bullet) and .22 LR (typically 40gr. bullet). It is my understanding that the rifling twist rate is different, so the heavier bullets may not be properly stabilized. My rifle remains original, decent bore but shows some corrosion, and will easily produce quarter-sized groups at 50 yards from the bench.

I think you did well at the price mentioned. Enjoy it!
