Those must be fairly long, being solid copper, even though they are not HP's.  What is the Total length on them?

The power bands help to reduce the friction but being long takes up powder space with increased pressures.

9 grains of Longshot would likely be a safe max with this bullet in my barrel... And would be right around 1,265 fps.

9.2 grains was just getting into compression, not heavily compressed... But the bullet was sitting on the powder.

The smile I got at 9.2 is not a bad one in my opinion...But it is visible.

I still think they could get up to a little over 1,300 fps in the 7" barrel... If I can find the right powder burn speed.

#9 is a tad too slow... Ran out of room before I hit pressure, mag primers might make a difference.

Longshot and Power Pistol are a little too fast...

I'm thinking 13.2 grains of #9 with a mag primer might be about as good as it gets with these.

Maybe 13.4 grains.... Just have to see if 13.4 will push the bullet back out sitting on the shelf.

13.2 is pretty compressed, 13.4 is even more compressed.


One thing is for certain.... Setback won't be an issue.

I would be interested in hearing the differences between CCI 300 and CCI 350 primers in 10mm.... In regards to velocity differences with the same powder charges.

Great info ridge!!...thanks for the leg work and results ;)

Im going to start with A#9 since I have a lot of it with CCI 350 mag primers...If I can get 1200FPS out of 5 inch Barrel and good groups, Ill be happy

Now its your turn, I gotta go back to work tomorrow so it'll be a week or 3 before I get anything else done.

Let us know how it goes.

Looking over Benchrst's 10mm data, what I needed to know was right there staring at me the whole time... I just wasn't looking for it until now.

He shows a load with the same charge of #9 under a 200 grain XTP, but one with a CCI 300 and one with a CCI 350.

The magnum primer produced 116 fps more than the standard primer.

Thanks for the Bullet length info...
QuoteLength is .723"
Longer than the 200 gr JHP's which are about 0.6800".
Did you try the Magnum Primer with the Longshot Loads?  The extra boost with a lees powder charge could bring about some results.  However your results are still very noble!   8)

No... I don't have any magnum primers yet.

Got a brick of CCI 350's yesterday, loaded 3 rounds with 12.4 grains of #9 for starters.

May get to shoot them this weekend.

I seem to hit a wall at about 1,275 fps no matter what powder and primer combo I use...
