Dr. Drew. RST offers a 16 ga 1 oz load at 1200fps that termed Lite in 2.5 in that I have been using on Texas wild bobs, think these are safe in my W J Jeffery 16 marked 2 1/2 in 1 oz 3 tons per sq in? Only use about 150 shells per season and reload low pressure 3/4 oz or 7/8 oz shells for skeet and SC.
