Fellers for all that wanted to know the Factory "XF" Remington choke measures .526". The 9.5 APEX TSS apparently loves this choke. It shoots best with a barrel that is dirty.
40 yards
30 yards clean barrel
30 yards fouled barrel. As you can see the dirty barrel at least in this gun is the ticket. Someone posted that so I had to try it. I shot a box of dove loads through it then shot another pattern. It made a world of difference, at least in this gun.
I shot some dry paper catalogs at 40 yards with the #6 nickel plated lead pheasant loads I had been using and with the 9.5 TSS. The penetrations was equal for the most part with a few of the 9.5 TSS pellets going through about another 1/4".
Once again I apologize for not already getting this info for those that wanted it. About the time I was getting into this I had to take over the company I have worked for the last 35 years.
