Hello to all members, I am new to this forum and looking for some good advice with experiences you may have had. I am an archery hunter and just purchased my first hunting rifle to start doing some rifle hunts. I purchased a Sako A7 RoughTech Stainless in a 7mm Rem Mag. I have a Leupold VX-3i scope mounted with CDS dial. I do not plan on reloading so looking for the best all around off shelf hunting ammo between my choices below: Ammo: -Nosler Trophy Grade Accubond 160 grain -Nosler Trophy Grade Accubond 140 grain -Hornaday Precison Hunter ELD-X 162 grain -Barnes Vor-tx new long range 139 grain Animals: -Elk, deer, antelope and bear Shots: -100 to 600 yards I just broke in my rifle and shot some Hornaday Superformance GMX 139 grain ammo. They shot extremely tight at 100 yards. All bullet holes were touching. Defiantly shot the tightest out of other brands mentioned above. The reason I do not want to shoot these, I heard these require a minimum of 2300 FPS to fully expand which puts a maximum distance of 435 yards out of a 7mm. Been told to stick with one of the bullets mentioned above that will provide maximum expansion and mushroom effect at any distance. Please provide me with some insight or what you would recommend. Looking at ballistics on paper, the 140 accubond seem to outperform in all categories. But also heard a lighter bullet could drift more in the wind. Look forward to hearing your opinions and experiences. Once I decide on one or two of these mentioned, I plan on shooting out of my rifle to find the tighest shooting. Since I am going with a CDS dial, need to perform this test before sending my dial off. Thank you.
