Barrel 3, Daisy Precision Ground Shot, Daisy 499B 7 meters rested. Not the finest BB in this barrel. This thankfully concludes this series — I’ll post a spreadsheet and graphs soon.
Res ipsa loquitur: smaller numbers = tighter groups
I think I’ll go with Barrel 3 and the inexpensive Daisy Precision Max BBs (or Hornady Black BBs) for every day offhand 5 meter shooting.
It seems clear that Barrel 1 (the original barrel that came with the 498B) is the least accurate with any BB, so I’m happy I sprung for the 2 other Barrels (sold by Daisy for only $12 each plus shipping).
It seems also clear that Daisy Unplated Shot is an excellent BB in all the barrels (but the most expensive of the lot at about 1¢ per round). I’m not so impressed with Daisy Precision Ground Shot (often touted as the BB made specifically for the Daisy 499B smooth bore “rifle”).
The good news: all this shooting cost me well under $4 for the ammo. Gotta love shooting steel BBs!
