Any advice on loads or whether you think its worth changing to AI would be much appreciated
I am a big fan of the 7/08 and feel it is in a leage of it's on. So when I started thinking of more
I went to the 7/08x40 (AI) and was disappointed with the amount of performance increase.
With the 140s the AI would only best the 7/08 buy 75 ft/sec and the 120 loads were only
30 to 50 ft/sec morethan the 7/08 ( The varget load with the 120gr NBT of 45.o grs achieves
3150 ft/sec average velocity in the 7/08.
I'm not knocking the 7/08x40(AI) but it was a lot of trouble to get dies and then to fire form
So I re chambered the rifle In 7mm WSM
and it did what I wanted 3300+ ft/sec with a 140 gr
Accubond in the 23" barrel.
If you are planning a new build in 7mm and a short action this is what I would recommend and
you could keep the 7/08 and even Elk Hunt with the 7mm WSM and 160+gr bullets @ 3000
You would have to open a standard bolt face up if that's what you have for a don-er but that's
And if I haven't talked you out of a 7/08x40 I have 100rds of fire formed once fired brass and a
set of dies for sale for it.
