As a result, many of the shot pellets are deformed as they scrub down the barrel. When these deformed pellets leave the muzzle, they scatter big time, even from a full choke.

Why do the deform...How is it different than any other size shotgun

The pellets kinda slam together when the shell ingites as well as in any restriction points such as chokes which will cause the soft lead to deform some.

All lead shot deforms. It deforms from the shot all pushing against each other, and it is scrubbed extensively as it travels down the barrel. The more shot exposed to the barrel, the more deformed shot. All of the gauges do this, but the 410 does it more because more of it is exposed to the barrel because of the longer shot column. Even the plastc shot cup does not prevent shot deformation. It helps, but does not prevent it, at least not all of it.

I know it does that I just don't see how it does it anymore than a 12 or 20....I'm interested in this now....looks like some testing soon....I will post pictures and results

I'm gonna take my Mossberg bolt action 20ga Winchester 1300 12ga, and the fie 410 all full choke and see what kind of patterns I get

This is a good idea, but if you are going for comparisons, be sure the following conditions are met. First, fire all guns at the same distance, 40 yards is preferrable. 2nd, make sure all of the shells are the same; i.e., all shells should be the same brand and the same type within each brand. 3rd., the shot size and shot quality should all be the same. If you use a hard premium shot in one gauge and then use a cheaper softer shot in another, you will not get accurate results.

Yea I'm going to use federal game load #4s and I will prolly do 30 yards I think 40 is a little far for a 410....I will do it tomorrow afternoon and try to get the info posted by tomorrow evening

Make sure you shoot your patterns on a large piece of plain paper such as butcher paper or large sheets of cardboard, and shoot several patterns from each gun. If you just shoot at a tin can or a cardboard box it will prove nothing.
