I've done some tests with Accu-bonds this summer and wasn't overly impressed with them. Scirocco, I found, have better weight retention. Swift A-Frame, oddly enough, has probably the best weight retention among most hunting bullets.
I shoot a Browning ABolt II composite stainless stalker topped with a Bushnell Elite 4200 2.5 x 10 x 40 mm on Weaver see - through mounts with Williams open sights chambered in 7mm Rem. Mag. Scope zeroed at 350 yrds and sights at 100 yrds. I only shoot Winchester Supreme 165 gr. Accubond CT and I'll tell you I get sub MOA results up to 250 yrds. I switched from Winchester Supreme Nosler Ballistic Silvertip 150 gr (which also shoot great) At 394 yards, on my particular rifle, I still get 1.625" groups, in which I think is capable of dropping any big game. Although I must tell you, it's not just the rifle but the shooter. I shoot my rifle quite regularly and have built confidence in the rifle and quite comfortable with it.
I have a system I use in Whitetail hunting during the rut that seems to work for me. When I make a mock scrape in the area I wish to hunt I will place a couple of 35mm
film canisters (film removed of course) in the scrape after I have cleared out all leaves and other debris. The film canisters are filled with cotton balls and saturated with doe in heat urine. This keeps the urine from soaking in the ground and can be refreshed on each trip if needed. I will also use the tarsal gland of the buck...
