Do not buy ammo in bulk until you have tried a box in your rifle. The velocity doesn't matter. The price of the ammo makes no difference either. Only the accuracy out of your rifle matters.
Keep in mind, that if you hit anything you didn't want to, you are responsible. Even if it's a mile away.
The bullet construction/type matters. An FMJ will go a very long way and bounce off hard stuff. A varmint bullet will break up if it hits a blade of grass. M885 ammo is AP. You don't need AP.
Every shooter will say a "good price" is different from what you do.
"...55-62 gr..." Rifling twist will matter for the weight.
"...reasonable shipping..." Shipping prices are set by the carrier not the seller.
