On a few threads i have heard comments about the 9X25 Dillon. Could someone shed some light on this subject for me. Is it basically a 10mm necked down to 9mm?
 
Yes. The idea was to generate the maximum gas volume to make the compensator work more efficiently. Unfortunatly, the 88gr bullets rarely stabilized. About the lightest bullet that seemed to work well was a 108 gr, and most wound up using 115's. For not much greater reduction in muzzle lift, you were rewarded with a horrible muzzle blast, reduced comp life, and a big gunpowder bill.
 
I've heard the 'excessive muzzle blast' remark from several people. I used to shoot a .357 using either 125s at 1750fps or 160s at 1350, bare; but only until I got my single chambered comp.
Sure it did a lot of target damage at near-contact range (leave a hole you could easily toss a softball through and blow all the pasters off the top half of the target); but I never heard anyone ##### about the noise.
Would the 9x25D really be worse than that?

It didn't leave the hole yours did as the blast was directed through the compensator (all efficient open guns can get very close to targets and only put a bullet hole in them - as the blast goes away from the target) but the noise was definately worse - as some of the ports directed the blast back to the sides and up.

Flattest race gun I ever shot was a 9X25. Running H110 sure made that comp work well.

All the other negatives already posted were there too. Disintegrating comps, huge powder bills, reduced capacity (well, in the US) expensive, hard to get brass that had a very short life.

On the plus side, the shooter could practically do anything he wanted. All the officials were too busy cringing to watch for foot faults or trigger fingers. :D
