[QUOTE="RockyMtnMT, post: 1800133, member: 7999"] Out to the range of 600y there are a lot of good choices. For me and what we do, vel along with a bullet that can handle it is king. [USER=13632]@bigngreen[/USER] is right on. It wasn't many years ago that pushing bullet well over 3000 fps was not really an option. Bullets couldn't survive the launch and if they could there was a high potential of a train wreck if you made a close range shot with the bullet coming undone on impact and not getting penetration. So when forced to use a bullet that is heavy for caliber in order to keep the vel down, bc becomes a big factor at 600y. Take the same cartridge and launch a bullet at 3300 for 3400 fsp, suddenly shooting 600y is more like shooting 300y. A 7mag running our 143g Hammer Hunter at 3300 fps has an impact vel at 600y of ~2200 fsp. Take that same bullet an put it in a 28N and run it at 3600 fps and now your impact vel at 600y is ~2550 fps.

What I do know for sure is the Hammer will not have any issue high vel launch or close range high vel impacts. Speed kills! [/QUOTE]
