I picked these bullets up as blems.  I thought that it was a typo and meant either 35 or 40 grains - never seen a 30 gr VMax component.  Surprise, they are 30 Gr - I then remembered that Hornady has a VMax load for the 22 WMR.  Yep, these feature a 30 Gr VMax - published velocity of 2200 fps.  Now for the question, how fast to load them in a 22 Hornet.  Think they will hold up at 2800 - 2900 fps?  How do you know that they are vaporizing in flight other than no hole at the target?  I 've never personally witnessed this before and am wondering if it is pretty obvious when it happens.

Quite often you can see the bullet disintegrating, a sort of blue streak in the air in front of the muzzle. This is because they slow down REALLY quickly when they come apart like that.
Whether they disintegrate or not depends to a certain extent on the smoothness of the bore in your rifle.
 
According to some computations I just made (which generally give pretty accurate results) in a typical Hornet you could drive them with safe pressures to around 3400--that is, IF they hold together. If they did hold up that velocity they would probably expand real well!
 
I'd use data for the 35-grain Hornady and see what happens!

Thanks for your insight.  It is very nice to have you and other people on this site sharing their extensive knowledge in the various discussions on these forums.  I have picked up a lot of very meaningful information since I started visiting.  I loaded a few rounds last weekend, but didn't get to try them - it rained both days.  I decided to try a starting load of around 2800 - 2900 fps and see what I get.  I used QuickLoad software to get a good starting point and compared it to the data for a 35 Gr Vmax.  I figured that I would start there and then see if I could get them to around 3100.  That's fast enough for me if they will hold together and give the desired level of accuracy.  I use QuickLoad to get a good starting point when there is no reliable data to use for that purpose.  It has worked well for this purpose as well as others.

I'd be very interested in hearing how it all works out!

Actually, I also just heard that Barnes is now making a 30-grain Varmint Grenade just for the Hornet. That should be a zippy little bullet too--and would for sure hold together at 3400-3500 fps.

Berger and Speer are also making a 30 Gr bullet.  I tried some of the 33 Gr TNT's, but the particular load that I tried wouldn't shoot as well as a 40 Gr VMax load that I was already shooting.  I need to do some more experimenting with the TNT's.  I tried Hodgdon Lil' Gun with the 40 Gr load and it shoots great.  It doesn't work as well with the smaller bullets because of the bulk density.  I also like Ramshot Enforcer because it burns so cleanly, but I think Winchester 296 looks to be a better match with the 30 Gr bullets.  I hope to find out tomorrow if the weather holds up.

i use the 35 vmax in a raging hornet with 13.5 grs of 296 , at 2200 fps, but the gun does best with the 40 gr. vmax 11.5 gr 296 at 2000 fps.
also use the same loads in a cz hornet, with 3050 fps, and and 3900 fps, never could get quite to 3200, even with partial resizing and the 35 gr wasn't as accurate as the 40 -- if this helps any

geezer,
 
Yeah, but the Barnes bullets are non-toxic! Which means you won't get lead poisoning from eating prairie dogs....
 
Actually, I have gotten excellent accuracy from the Varmint Grenades I've tried, even the ral lightweights like the 26-grain .204. I suspect part of the reason (other than them being really good bullets) is that they are longer than lead-cores, so match the rifling twist a little better than some other lightweights. Which might be a very good reason to try them in the Hornet.
 
For an all-around varmint bullet in the Hornet, though, I do like the 40-grainers--if your rifle will handle their length. Which is why I like a single-shot Hornet. The 40 Ballistic Tip and V-Max just work better at about all ranges, if you can use them.

I tried some out on Saturday and boy are they explosive.  I didn't try to push them too hard and maxed at 12.0 Grs of W296.  I had another rifle that I had to work up a load for so I didn't have as much time to spend with the Hornet.  It was a bit windy and as I surmised - these small bullets don't hold up in the wind very well.  I shot pepsi cans filled with water from 100 yards away and the cans were blown into as many as five pieces.  I didn't get a chance to run any rounds through the chronograph, but that's a good excuse to go back and do it again next weekend.  I plan to increase the charge a little and see what I get - just not to the point of reduced case life.  I got a chance to shoot a few groups Sunday when it wasn't as windy.  Groups were under an inch at 100 yds - my last six shot group measured 0.61".  An added benefit is that the point of impact was in line with the 40 Gr load that I usually shoot from this rifle - the difference being that it shot about 3" higher.
