I use the 117 Sierra Pro Hunter bullets in my 257 Wby. Seems to me the long freebore Weatherby's don't get along with Boat Tails very well. I have taken Pronghorn, Deer and Elk with these 117 Pro Hunter bullets.

If a rifle won't shoot a flat based Sierra, the chances of it shooting much of anything else plummet. The flat bases tend to be very tolerant of distance to lands, making them ideal candidates for factory ammo that attempts to shoot acceptably in as many different rifles as possible. Heck; its the easiest way to make an accurate combination for ranges where accuracy isn't very important at all.

By the time accuracy matters a little trajectory and wind matter a lot.


Life begins at 40. Recoil begins at "Over 40" Coincidence? I don't think so.

Sometimes it isn't just the length of the freebore, but it's the diameter as well. A min diameter freebore only a half thou over bullet diameter will mitigate alignment issues.

No worries about a pro hunter getting the job done. They work!!

Never get to old to learn , so I am asking . i know the flat based bullets are good to 300 yds as that is part of score shooting ranges . I have read the boat tail is better at longer ranges . I have not shot longer ranges as my experience in competition has been 100 yds and 150 yds or less at big game .
But was wondering if the oprotunity arose how would they fare at longer ranges ?

Not meaning to be snarky at all, but a few minutes spent calculating trajectories on a JBM Ballistics would be very enlightening to you.
