I did some testing on "wad-pressure" it takes a minimum of 60 pounds pressure and a sabot tight enough to hold it to maintain minute of angle accuracy.
With the vent liner installed and the channel between the 209 and the vent-liner drilled with a #21 and polished has reduced the carbon problem to cleaning it out when I clean the gun after shooting and my numbers and targets show an improvement in consistency so my opinion is that I am also getting either better ignition or more consistent ignition.
Mike did a very similar vent liner install maybe he will comment on this for us. Lee

Cabelas has Federal 209A primers in stock right now but they come in quantities of 1,000.

Thanks for all the great post.

I am compressing the sabot hard. I do not tap on the bullet with my ram rod. I have the specific bullet tip for the Barnes Spitfire. I just lean on it hard and do that a few times. Maybe there is a better way and this is part of my problem? I am in southern Michigan and temperature was in the 50's when I had the hang fires.

I am using the Barnes Spitfire T EZ 290 Grain Bullet & Sabot.

I will try to get a chance to shoot these Winchester Shot Shell Primers and see what happens. Right now I am hunting every night. Saturday I will have a chance to shoot a few rounds.


Let me know on the compressing of the powder if there is a better way.

Thanks Again for All the Help!

you should not have to tap on the ramrod, just leaning hard is fine, But, not only do you have to compress the load, but the sabot has to be tight fitting, so it will hold the pressure on the powder. If it is, and you get some new, more powerful primers, you should be fine.

I am going to Cabela's today after work for the hotter primers. I will probably get the CCI 209M primers.

THANKS AGAIN!!!!
