Re: thoughts between a 308 and a 300 win mag build?
so
1) Is this a custom build?
3) are you reloading?
4)why are you only looking at the 308 and 300 win mag?
I can help with a few of these haha...the 308 will have NO punch after 800yds putting it well outside of the 300 win mag category! and for people telling you recoil is an issue with a 300 win mag, unless you are not putting a break on it...than yes I agree, but with the breaks out there today recoil is not an issue anymore regardless of the caliber and if it is I feel for you haha. Hell if the 50 cal can be tammed to where kids are shooting them, then is recoil with the 300 win mag a concern with a break? Thats nonsense. Plenty of competition shooters use the 300 win mag with no issue for 1,2 and 3 day events.
Here's where I would challenge you...why a 308 or a 300 win mag? why not a 7mm which has better BCs and ballistics than both and 1200 yds is nothing for that caliber with less recoil, or why not a 7-08 which is standard cal (instead of the 7mm's that are magnum cals like, SUAM, WSM and Remmington Mag) where you have decent ballistics, 7mm BCs and punch at 1,200 yds? just some different ideas for you to look into.
But if the decision is either the 308 or 300...I would hands down take the 300 win mag as my all around rifle over the 308. 308 can not shoot the 30 cal bullets with the best BC like the 190s, 208, 210+ at the velocities necessary to take advantage of the BCs, so you are stuck with lesser bullets moving slower with no knock power past 800yds. Also because the 300 can handle the heavier as well as the lighter bullets, you have a wider range to shoot from...you can load a 300 down to 155s and lessen the recoil and still smoke the 308. The only way in hell I would take a 308 over a 300 win mag is if ammo cost is an absolute make or break for you, or you had a concern for barrel life. If neither of those are an issue...then 300 win mag over a 308 all day every day.
