Rossi .45/.410

[Rooster17]

Is it counter productive to shoot .410 rifled slugs through a rifle barrel? I know nothing about slugs. Was thinking about buying a Rossi....

It shouldn't hurt the gun, but accuracy will probably get worse.

Sabots are made for that

There is a significant difference in diameters between a 45 Colt (.452"-.454" usually) and a 410 slug (something well under .410" in order to safely be fired in a Full choke barrel). This would probably lead to a rather large amount of gas escape=int around the slug as well as the slug unpredictably wobbling down the barrel upon being fired. This is not conducive to accuracy in the least and one can readily see this when firing .452" diameter bullets down the larger 45 Colt bores. As the difference in bore size is even greater here, I suspect the "accuracy" would even be worse. From shooting standard Foster style slugs in rifled bores, you will also likely see a significant amount of leading between the grooves which not only affects accuracy with 45 Colt loads but may also increase pressures as well as lead to a long and difficult cleaning job.


As for a 410 sabot slug, is there even one out there? I don't think even BPI has any and they have a fair bit of oddball stuff. In any event, the same issues regarding standard Foster style slugs above would apply here, possibly even to a greater extent. You are dealing with a greatly smaller projectile size being used in a larger diameter "pipe" for all intents and purposes. This works with shot to an extent as the wad and shot, plus the overpowder cup to an extent will expand to fit the bore. This locks the powder behind the shot giving it a decent velocity. One sees this with the various chamber inserts for shotguns.

So, slugs are likely a no go as they are too small of a diameter. Stick with 45 Colt rounds when one needs to fire a single projectile.

I agree, a .45LC is basically the slug for these guns.
