Tell us Smoking 24/7/365 what differences have you logged in the ballistics and performance overall of ammo bought from any specialty sportings supply store versus the same exact specs and mfg. of ammo bought from a Walmart??
Inquiring minds want to know!!
When I receive a new barrel or gun, I shoot it offhand using the B-19 target for a minimum of 150 rounds, per type of ammo. I mark and log all of my targets and arrive at an average score, bearing in mind that how I react to a type of ammo through recoil and sound is as important as how the ammo absolutely shoots.
Once I have the highest average scores, I note the best ammo and destroy the targets. The best-performing ammo is usually what costs the most. Federal Standard Velocity is a decent cheapy. Model 41s love Green Tag. K-17s are finicky but come alive with Aguila Standard Velocity. Wolf Match Target is great, but it can give FTEs. I have never been able to wring much out of Remington Target. Eley is impeccable, and their various classes are beyond my ability to measure. Perhaps rimfire benchrest shooters can notice a difference. My favorite all-around ammo is Aguila. It's affordable, and you'll see it on the 2700 and Standard Pistol lines. I've tried it all, it seems, and I have little desire to wander, at this point.
That bulk stuff is so inconsistent that it's really only to be used for having fun shooting cans with a 10/22.
Has anyone shot a measurable amount of SB Club ? I have one box, and the quality is meticulous. I don't dare shoot it.
