Re: 7mm 175 smk?

Fiftydriver. I am using 60 grs of rl-22 with the 162 a-max at 3050fps. I loaded the 175 with 59 grs rl-22 at 2975fps. At 1000 yards the 175 dropped 3 moa more than the 162 and 1500 yards 6 moa more and had to use more windage at 1500. I think it is due to a lower bc more than lower launch velocity. I will be in montana on a hunting trip for 2 weeks at the end of october early november. If i get a chance i will stop in at your shop.

Re: 7mm 175 smk?

Fiftydriver, the results confirm what I have been seeing in my own shooting. The poly tipped Hornady bullets have real world BC's way above their printed values.

I am not sure if this is mostly due to the plastic tip or overal bullet design. I have compared these in a variety of cals to the traditional HP match and VLD bullets. In every case, the Hornady's just fly flatter, especially when ranges stretch out.

308nate, Rem700: I would suggest you give the 162gr SST a try. It is even longer then the Amax so should have a higher BC. The Amax is listed at 0.625 and we know it flies better (probably like a 0.7). My guess is that the 162SST are over 0.7, probably closer to 0.8/0.9. Pretty amazing stuff.
