I just purchased a Tikka T3 Varmint .223 with a "1 in 8" twist and have a Nikon Monarch 4X12X40 on order.

From what I understand, the faster rate of twist is intended for primarily heavier bullets. I've read some material on the subject but still don't totally understand "rate of twist" and how it relates to bullet selection. I'm not a handloader (yet) and sure would appreciate any advice concerning factory ammo and bullet selection.

I plan on shooting the rifle at the range with my 13 yr. old son and thinning out the coyotes I should've taken out last deer season.
