Home Forums Reloading Big Game Rifles Flat based bullets

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.

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!!

thank you , it is very interesting , Kenneth
