Shelby - you are most welcome. Thx due also to Mike (Murray Nevada) and Frank (FJC) for helping out with some ammo supply aspects.
Of course .... results are from one man and one gun so - as I'd always say not necessarily totally definitive but .... struck me that any results and feedback just have to be useful and hopefully therefore, helpful to others.
I plan to add a bit more when possible ... but certainly it helped me make a better and more informed decision re ammo.
