I hope my Savage 308 will reach a mile, only one way to find out.
I am switching to Lapua 155gr scenars bullets for a while with Varget powder. I'll see how that works out.
If the 308 doesn't reach a mile I'll switch to the new 6.5-284 and test it out!
Last year at summerland I stretched my 308 out to 1500 yards. Made 3 consecutive hits on a 1 moa target. At that time it was 175 smk's over 46.7 grains of varget travelling at about 2810 fps. Have since switched to 175 bergers over 45.8 grains flying at 2750 fps. I have a nightforce 5.5-22x56 with a 20 moa rail. I used all the internal elevation in my scope and was holding over another 7.5 moa in the scope reticle. I have no dought that with the right conditions it will make it there it comes down to needing more elevation, possibly a 40-60 moa rail. I think it was something like 72 or 77 moa of adjustment to get to 1500 yrds.
