You've got no worries mate!!!

My brother has used the 7mm-08 since it came out, I believe the year was 1980...During that time he has used different ammo and keeps coming back
to the 140gr Remington CoreLokts...I'll bet he has killed over 200 deer with
that loading...He also ventures each year to either Texas or Saskatchewan, never
a problem...

There are alot of very good deer calibers out there but you will be hard pressed to find one much better than a 7mm-08...
