Hi, I'm tired, really tired to read or hear so many cheating "experts" say or advise hunter/shooter or simple novice to use two categories of new caliber.... The trend of WSM, RSM and "pro" URM, EDGE, Lapua etc... The true is the following for hunting or LR shooting YOU DON'T NEED to look for new "exotic" calibers !!!!!! It's good to look into the future but in this case, it's a cheating lost of time... Firstly, If you use a "classical" 7mm Remington Magnum you have the best caliber for hunting and LR shooting. Only one rule...... it's to select only good component : Norma or Nosler Brass, CCI 250 primer, Sierra (160gr SBT) or Berger (168gr HPBT) Bullets and last but not the least a top powder like Norma MRP, Vithavuori VN, Hodgdon Retumbo or H1000. The Rifle ? a good custom rifle with a 26ic Match cut barrel or a good production rifle. With this "basic" equipment, you should be able to get usually +3050/3100 Fps with a 168gr and 3000 Fps with a 175 or 180gr bullet. Of course you can reach more speed with a "LARGE OVERBORE" like a 7mm STW, RUM or a 338 "SUPER SATELLITE" but for what price ? More recoil, more powder, brass cost. You will need a longer barrel to extract more velocity, that is to say an heavier rifle. Last but not the least, you'll wear out your barrel far quickly than with a 7mm RM. Some of you, are already thinking that they can get the same performance with their WSM honey... No buddy... The bad true is the following : Today classical Magnums like 7mm RM or 300 WM are down loaded !!!!! If you load your 7mm RM at the same pressure than a 7mm WSM, you will extract 100 fps or more with a 168grs bullet... New slow powders allow to maximize the 7mm RM potential. Last word.... you don't need a 300 or a 338 caliber !!!! a 7mm Remington Magnum with a 168gr Berger Bullet at 3050 Fps retaine more velocity, energy and less drop at 1000 yds than a 300 RUM... it's a fact !!!!! it stand with a 338 Lapua at 1500 Yds...... no comment ! I have used the recipe of the 7mm Remington Magnum with a 160gr SBT or 168gr HPBT Berger Bullet with a 26 ic Barrel, stout load with top powder since many years now, and I can say you: it's the best in the field.... Today, I have read so many posts, articles with bias.... it's funny !!!! Only once I have heard something of right : It comes from the "best of the west" crew team. They use and recommand a 7mm Remington Magnum with a 168gr Berger Bullet under a stout but safe Retumbo load through a 26 ic barrel.... I have no time to put "figure" so look their web site (video, forum, articles) and maybe you'll understand... the link is the following : The Best of the West - Home See you I hope to help some of us to make a right and reasonable choice !!!!
