Daisy Daisy 499B Muzzle Velocity

Wow, that is fast. My 499 is shooting at 245 fps. Want to trade? This guy substituted a Red Ryder BB gun spring and got 324 fps. Maybe that is it.

Hey JDR, I kind of thought the same thing, that maybe Daisy mistakenly used a Red Ryder spring when they built my gun. The only problem with that theory is the stronger Red Ryder spring would increase the cocking effort required to about 15 lbs. Here is Ron Spomer on YouTube measuring the effort needed to cock his Red Ryder:


My 499B requires about 8 1/2 lbs effort to cock. From what I have read, that is about right for a 499B.

Thanks to everyone who has responded about the muzzle velocity of my 499B. As a double ckeck on the results I got with my Garmin chronograph, I dug out my old Pro Chrono chronograph and ran a 10 shot string over it using the same Daisy Precision Ground Shot. The results were nearly identical as with the Garmin: average mv of 322 fps, high mv of 324 fps and low mv of 321 fps. Now I'm more perplexed than ever as to why my 499B with 100% factory stock innards is shooting so much faster than it is supposed to.

I did more digging on the web and found a blog entry Tom Gaylord did for Pyramyd Air in June , 2021. He reviewed a new 499B, and using the same ground shot I did, he got an average mv of 263 fps, high mv of 265 fps and low mv of 261 fps. So, the gun he tested is faster that most of the results reported by y'all but still a lot slower than my gun. Gaylord also measured the cocking effort on his gun and it was 8 lbs, 7 oz which is right in there with my gun's 8 1/2 lb cocking effort.

I guess my next step is to email customer service at Daisy to see if they can shed any light on what is going on with my gun.

I sent an email to Daisy this morning about my 499B. I'm sure their first priority is answering "real" customer questions about parts, warranties, etc., so I don't know if I'll receive a reply or not.

I also got around to benching the gun to see if there has been any change in accuracy. Firing 5 shot strings at exactly 5 meters using Daisy's precision ground shot, I'm getting groups that are consistently at or below 0.35 inches c-c. That's using a Caldwell Rock Competition rest and as light of a hold on the gun as I can manage. The gun's accuracy is about the same or perhaps a shade better than when I bought it.

Try a 499B, I heartily recommend owning one. So here's the story of how I ended up with mine.

My parents didn't have any interest in guns so I was never given a BB gun when I was little. I was in Cub Scouts, though, and as a Christmas present my favorite uncle gave me a subscription to Boy's Life magazine. Reading the articles there and seeing all the ads for .22 rifles lit a fire in me and by the time I was 9 or 10 years old I was a full-fledged gun nut. I kept pestering my dad for a .22 and he told me okay on one condition -- I had to pay for the gun with my own money and buy my own ammunition. I saved all my paper route money until I had enough to buy a Remington 572 pump .22. I went to the Western Auto in town and plopped down $65 for it and boy, I was on cloud nine!


That gun kept me going for hunting and plinking, but I soon developed an interest in NRA Junior competition and wanted to shoot in the programs the American Legion and the volunteer fire department in my little town sponsored. I needed a proper target rifle for that so I scrimped and saved my paper route earnings until I could afford a Remington 513T TargetMaster. That gun taught me how to shoot with aperture sights and I’ve loved that style of shooting ever since.

Fast forward 50 years and I'm retired. For some crazy reason I developed an itch for the BB gun I never had as a kid. I looked around and discovered the Daisy 499B. Thinking about that gun brought back a flood of happy memories of shooting formal competition as a kid. I knew that no other BB gun would do, so I ordered a 499B. I love that gun and it is one I will never part with.
