Winchester High Performance 22; anybody tried them yet?

seems to imply there are round-nosed 40-grains. I have yet to see them personally, though.

Oh OK, Those are the Super Speed ones that are shown in the starting post of this thread. Yes they seem to be avail in both RN and HP. Although I have never seen the Super Speed ones in either flavor myself.

I thought you were saying there was a Round Nose PowerPoint. No.

It would sure be fun to try out, I guess.

Btw, what is the difference between powerpoint and dynapoint?

I'm not 100% sure but I think the PowerPoint is higher velocity than the Dynapoint.

The PowerPoint definatly has a nice big hollowpoint compared to the little one on the Dynapoint, it looks like it was made with a 1/16 drill.
 
These are NOT the same as Winchester PowerPoint - the PowerPoint is a 40 gr HP at a somewhat higher velocity than usual, while the SuperSpeed is a 37 gr HP. This is the usual industry solution to obtaining higher velocity - drop some weight. The price that is paid, however, is the more rapid loss of velocity over longer range. You can't get something for nothing.

Now I realize that we are not talking long rang here as it's "only" a .22 LR, but the drop from 40 gr to 36/37 gr is somewhere between 9 and 10 percent - not inconsiderate when talking about mass...

I have used the 40 gr PP for a number of years now and like it a lot, however the CCI Velocitor is a better round across the board (velocity means and SD, QC, mean accuracy in multiple firearms, etc).

but it actually happened the other way around. Soon after the .22 long rifle became standard the 40 grain solid became the standard. When the velocity was jacked up to the present advertized 1300 f.p.s. these rounds were designated as high velocity or super speed. In Canada C.I.L. called them whiz bang. Later hollow points were created by taking out 3 or 4 grains of lead. The reason was not to enhance velocity but to create a mushroom bullet to enhance terminal performance on small critters and in fact C.I.L. called their whiz bang hollows, mushrooms. Velocity was slightly higher and in the advertized 1330 range. Today most companies make their 40 solids the same shape as their 36,37, or 38 grain hollows. The 40 grain hollows such as the Win. PP and the CCI Velocitor are a more recent creation. CCI chose to significantly increace velocity and therefore pressure to drive their big 40 hollow, but Winchester chose not to exceed high velocity or super speed pressure hence. the slightly lower than 1300 f.p.s. advertised velocity.

I have tried both the PP and the CCI version and both provide good penetration and significant terminal damage. Slightly more for the velocitor. In my rifles the CCI velocitor is more irratic while the PP is very accurate. Last time I bought the CCI round it cost twice what the PP cost.

ps In recent years the industy have created hyper velocity and one of the tricks is what you mention and that is to drop bullet weight even more, resulting in the like of yellow jackets, stingers and quick shok.

I was trying to be more concise...;) , but you are absolutely correct!!
