Thanks for all the great replies. 8mm/06- I will try that remedy first as I have never heard of that. Thanks.

Oldelkhunter-- answer to number 1- I am probably not allowing the barrel to cool as needed so I will give that a try more between shots. I live in south florida so it takes a while for the barrel to cool. answer 2--- No I dont live any oil reisdue in the barrel prior to shooting so thats not the culprit.

Reference to temperature change---Even more challenging is that I live in south florida but hunt in the northern states, so I sight in in 80 degree weather at least then shoot in weather often 40 degress or less.

Briman-- I am usually cleaning between range trips so maybe I should try cleaning at the range then firing 1-2 fouling shots after.

Thanks again to all who replied. Any other info would be greatly appreciated as well.

Scott
