I offered to load for him if he buys the dies (I have a 7MM STW dies but not the 7MM Mag dies) and whatever bullet he wants but he insist staying with factory ammo. Anyways, not sure where he read it but apparently he is convinced that a 168gr will group better. HSM has 168grainers.
Shots will be all under 500 yards, most likely 200-250 yards. Looking forward for any information to pass to him. Thank you in advance for your support and understanding.
My number one go to bullet in the 7 RM was the 160 Partition. I did some experimenting with the 175's but decided on 160's for a little flatter trajectory. In my older and more wiser (IMO
) years, I would go with the 175's.
The only reason I consider Bergers is for their BC and reach to long ranges. That said, they are an extremely effective killing bullet when used within their parameters which for the most part is best using the double lung shot. High velocity tough angle shots requiring penetration is not their best suit. Although I have read some good reports on that, I have also read some not so good reports.
My philosophy on Bergers and similar type bullets is to go with heaviest for cal bullets for lower velocities and greater penetration. For inside 500 yard shooting, I would pick a 1 MOA 180 over a .7 MOA 168. The elk will never notice the .3 MOA difference.
Sounds like he is set on the 168's. Shoot them and see how they do
