Spoke with Steve from Hammer 2 days ago to get some load data for my 28 Nosler. He was very helpful and knowledgeable. I had been shooting Berger 195 EOL and am not happy with terminal performance of the Berger so had planned on ordering some 177HH. Steve asked how far I planned to shoot and I told him it's a hunting rifle and 500 yds would be long for me . He suggested the 143HH for that range and hooked me up with data for N570 and I should get 3500-3600fps with that bullet. He also told me if I wasn't happy with them send them back and he'd refund or swap them out. I spoke with him Tuesday afternoon and they were in my mailbox this morning!
