Carried the PB Thunderheads in my 45 Colt for the last two years. Started out with maximum H110 loads, but quickly determined that "I really don't care for that much recoil". I settled for a load providing about 1100fps with the 270s. I had no problem with accuracy and loved the loud slap as the bullet hit the cardboard backboard 50 yds away. Unfortunately, I did not get a shot on any deer, so I cannot comment on field performance.
I've been using Penn Bullets for many years; hunting, pistol competitions and plinking. I've always been impressed with their quality. I have not ordered recently, but a friend commented about awaiting for his to arrive. I'm still trying to get through my last order of 255gr SWC's and 200gr FN bullets. I had a similar problem with delivery from National Bullet. After nearly 9 months of NB having my money, they finally filled the order...wrong bullets, but at least I got from the money spent.
