there are some Daisy 499B videos about disassembly/assembly and accuracy tips on youtube from Caleb Schank at the Sure Shot

The 499B takes a lot attention. The easiest things are:
1)use premium Match Grade BBs,
2)be sure your shot tube snugs up firm and tape it in place.
NEVER use anything more than your finger/thumb grip to tighten the shot tube.

Shoot flys. I use a 2'x4' piece of ceiling tile as a BB stop. Then hang a piece of watermelon rind on it to attract a few picnicking flys. Ten feet is about right for the distance from your lawn chair to the target zone. The flys are fairly interesting to hit. Many of my shooting friends, real rifle...

Here is what I found in 2009: Size variations of various new (2009) BBs Daisy Premium #0040 (sorted 150) Avanti BBs (sorted 100) .1...

I have not checked all the available brands for a couple of years. Please post some results if do th...

I bought my micrometer on ebay, get one that measures in inch rather than metric. I should have mentioned that the 499s just take a lot of maintenance. They can drive you crazy trying to keep them around the 10 ring. One of the clubs out here just lines their kids up behind their 2 best guns. We ord...

Typical shot tube diameter is about .175. BB's that are .174 fly pretty straight. Measuring can be trick...
