Before we begin I want to remind everyone that today is the third of June. It’s the day Billy Joe McCallister jumped off the Tallahatchie bridge. (from the Ode to Billy Joe, written and performed by Bobbie Gentry.)

Today’s report will be short because I am reporting on the velocity of the Daisy 499B single-shot — the world’s most accurate BB gun. There is only one BB to use in this gun, though I will test several for you. But there is an interesting twist for us to explore. Let’s get started.

The twist

In the owner’s manual for the 499 I just received, it says the velocity is 280 f.p.s. But Daisy’s manual for the 499B has always said 240 f.p.s. in the past. And when I have tested the gun, that’s right where it is. Was there a change at some point?

Old Daisy 499 specs
I got this from an old Daisy 499B manual in the Pyramyd Air resources page.

New Daisy 499 specs
I’m not making this up. This is what it says in the manual that came with the new Daisy 499B.

Okay, someone went to the trouble to calculate the new velocity in meters per second. That shows that some effort was put into changing the data in this new-gun table. But they left the energy at 0.71 foot pounds/0.96 joules, when it should have been raised to 0.89 foot-pounds or 1.21 joules. And the old number of 0.76 foot-pounds was incorrect for a 5.1-grain BB travelling 240 f.p.s. It should have been 0.65 foot-pounds, which is 0.88 joules.

That tells me the new number isn’t a typo. It was purposely changed. Is it correct? Today we find out. Let’s get started.

Daisy Match Grade Avanti Precision Ground Shot

The only BB that is supposed to be used in the 499B is Daisy’s Match Grade Avanti Precision Ground Shot. A 499 owner knows why these are the best. All you have to do is drop one of them into the muzzle of your 499 and listen as it takes a long time to roll to the breech and click on the magnet. I have said that it takes 3 to 5 seconds in the past, but I think it takes less time than that. But the time it does take is much longer than for any other steel BB. And no — I will not try a large Marksman BB in any of my 499s!

I have run numerous accuracy tests in the past and these BBs have always out-shot any other BBs available. I will test other BBs for velocity today and I’ll test them again in the accuracy test, but in my experience, the Precision Ground Shot are the most accurate.

The correct way to cock and load the 499

I learned in a previous test that cocking the gun before loading increases accuracy. It turns out that’s the way Daisy wants it done! They even put it in the manual. First put the gun on Safe. Next, cock the gun. Third, drop a BB down the muzzle and listen for the click when it hits the magnet. This will be the way my Royal Rangers learn to do it.

Velocity with Precision Ground Shot

 Ten Daisy Precision Ground Shot averaged 258 f.p.s. The low was 252 and the high was 260 f.p.s., so a difference of 8 f.p.s. But let’s not make any assumptions just yet.

ASG Blaster

Next up were 10 Blaster BBs from ASG. They averaged 261 f.p.s., with a spread from 259 to 262 f.p.s. That’s only a difference of 4 f.p.s. Interesting, but no conclusions yet.

Crosman Black Widow

The last BB I tested was the newer Crosman Black Widow that has done so well in recent BB gun tests. They averaged 262 f.p.s. with a low of 261 and a high of 266 f.p.s. So a difference of 5 f.p.s.

What I saw as I was shooting was a gradual increase in vel;ocity. Was the gun breaking in? I believe it was and still is. The only thing to do was to re-test the Daisy precision Ground Shot.

Second test with Daisy Precision Ground Shot

This second time through Daisy Precision Ground Shot averaged 263 f.p.s. The low was 261 and the high was 265 f.p.s. — a difference of just 4 f.p.s.! I believe this does indicate that this 499B is breaking in. Will it ever get to 280 f.p.s.? Who can say? But it’s sure above 240 f.p.s. I therefore think the increase in velocity was intentional. It will sure be interesting to see how accurate this one is!

Cocking effort

The 499B has always been extremely easy to cock. I measured this new one with my trigger-pull gauge and it said the gun cocks with 8 lbs. 7 oz. of effort. That’s light!


The trigger-pull measured between 2 pounds and 2 pounds 4 ounces. It’s a two-stage pull that’s not terribly creepy but can be felt all the way through the arc of stage two.

This trigger is lighter than 499 triggers I have measured in the past. As best I can remember, coaches were allowed to get their shooters’ triggers down to 1.5 lbs. but no lighter.


What I see from today’s test is that someone from Daisy has breathed on the internals of the 499B. It ain’t just parts from China that get assembled in Rogers, Arkansas. Someone has listened to the coaches and then done something about it. That’s the stuff, Daisy!
