Choke?

[Parkerman]

Parker research letter says:

RH (150 #8 pellets in 30" circle at 40 yards)
LH (205 #8 pellets in 30" circle at 40 yards)

I have no idea of total pellets so I can't determine the choke in terms I understand. (like Full, or IM or Cyl, etc.)

Anybody help?

Thanks, Linn

hi, my thought would be a 3/4 oz maybe an 7/8 oz load. my guess would be full and mod with 3/4 oz of 8's if it were a 7/8 oz load of shot it would be imp-cyl and mod. scott
