Re: Beginner To Long Range - rifle, caliber, scope?
The 7mm and 6.5mm bullets generally have better ballistics than the 30 cals. There is a great article somewhere on LRH about the differences. I believe either Brian Litz or Eric Stecker from Beger Bullets authored it (I apologize to the correct author, if I am wrong). In short, the article showed that you need to shoot 230 gr. bullets in a 30 cal to get close to what the 7mm and 6.5 can ballistically do. They simply buck the wind better and have a greater window or margin for error with wind and elevation at 1000 yds due to higher BC bullets.
Having said that, the 30 cals can arrive at 1000 yds with much more energy to whallup big game. The 300 WinMag and it's shorter cousin 300 WSM don't have real impressive velocity when it comes to the 230 grainers. The 300 RUM
is the ticket for this bullet.
So - tastes great or less filling? Which is better: more forgiveness with the wind (better accuracy from higher BC bullets), or foot-pounds of energy delivered? So many of us got tired of having to choose. We ended up with the big 338's - Edge, Lapua, RUM, Norma, etc. Now we get both higher BC's and energy delivered. The trade off is heavier rifles/recoil and generally more cost in terms of powder, brass & bullets.
If you're talking targets at 1000 yds - go with one of the larger 7mm or 6.5mm caliber offerings. If you're talking big game at 1000, then the 30 cals in magnum pkg.
