Update 7/14

Well I have purchased and taken appart the following 3 brand of Sabot slugs.
I am making a matrix of the critical information eg. (Mass, diameter of sabot, dia. of slug, length etc )
I am going to shoot a few out of a smooth bore and get actual velocity.
I have had someone pull apart another candidate and based on his initial data it looks promising.
Once I get the partial box from him I can add it to the mix.

I will then have a few rounds of the finalists sent to the gunsmith for regulation checking.
If they pan out I will purchase a case, or 2, for final regulation and hunting.

They are :

Winchester BRI.

Lightfield Hybrid EXP.

Remington Buckhammer.

Hastings Sabot

( I know they are obsolete, I have a line on 300 rds (3 cases))

Details will follow.

Thanks
Nitro
