You should be able to get them to mag length. I think SAAMI is 2.80" OAL.
I shoot 45 grains Varget with them in a bolt gun. You will want to start around 43.5 and work up I would think.
Try 42.6 grains of hogden 4895 o.L. 2835 shot 5 shot group at 200 yds.7/8 in. outside to outside out of my gap crusader .308 extremely low velocity spread and not temperature sensitive.
I use H4895 in my 18.5" 308 bolt gun with suppressor. It is very capable of being highly accurate. But I am only hitting 2600 FPS with the short barrel and 175's.
I have a question... why would anyone run the Berger 175 VLD's when the Berger 175 gr BT Long Range has a higher G7 BC and to beat, is a tangent bullet, so likely to be less finicky.
Just curious as I just pulled the trigger on some Berger 185 BT long Ranges today. I have been running 175 SMK's.
