Nice!
They have some very good Creedmoor jackets at the club that shooters can borrow. Nice way to try before you buy, or if they don't have your size possibly one of us can let you try one on.
Offhand is where we all get our humble pie.
@mac1911 and I both practice offhand with pellet guns. Dry firing is good too- it trains your muscles and strengthens the ones you need. As I get older I find that I need to keep my back in shape for offhand or it gets pretty uncomfortable by the end of the stage. When your back hurts you start thinking "F it, I'm going to pull the trigger and get this over with". That doesn't help scores.
A little coaching on offhand helps too. Maybe somebody knows of a good youtube etc. The Italian Stallion at Pembroke can straighten out bad habits and teach some good ones. I once had some offhand coaching from a member of the Army Marksmanship Unit at CMP SAFS, but I could not quite throw my hip out there like she could.
Hope to make the November one. Fighting some crud in my lungs at the moment.
