Since you are the noob roaster, whaddya think you are doing making an overbore barrel??? You will blow an eye out or something...
(I have 2 9x25's. They won't let me play with them at any USPSA matches because they hurt the RO's and Roger at Burnsville asked me to not shoot them there after I consistently blew the overhead lights out with the comp.)
Well, technically you ARE correct, UNLESS you load the 9x25 Dillon cases with the Winchester 130 grain .356 38 Super bullet!!
In reality, considering the pressures involved, that one mil won't make diddly squat of difference with the hot 9x25 loads because the base of the bullet will upset and seal the bore no matter what, and last I looked the lands on pistol barrels were a touch more than 1/2 mil high per side....
That being said, I DO have an old and cheap ($349 NIB) EAA 10mm that's already Magnaported, so if I get a plain old 9mm or 38 Super Witness barrel, I may be in luck.
BTW: Got any 9x25 loads and chrono data you'd care to share??
Had to pull the data out.
These work in my guns, but are a little different.
9x25 Triangle custom ramped barrel (Briley barrel)- This was the old IPSC Major (175 PF) I will note that when I did these, it was back in my "that which does not kill me" phase of reloading, so I did run things up past the sane point. There was no reason to try and get better than 200 PF other than to prove I could. Crimping will make a substantial difference in load performance. Tighter is good. If it is not well crimped, there can be some bullet migration which causes issues. All of these loads had bad SD variations until I figured that out. This is not a reloading chore for folks who have no other reloading experience. Its a lot like the .357 SIG, but a lot more oomph. I will also add, it is quite obnoxious to folks around you. The only thing I have seen worse is a comped 9mm Win Mag or a competition comped SBR M16 in .223.... Rob Leatham supposedly developed arthritis in his wrist from one of these. The comps work very well with them,so the recoil is all straight back
110 grain JHP .358 bullet 16 g 296 1.255 OAL ( to crimp groove) @ 1700 FPS
115 grain Zero JHP .355 bullet at 1.250 OAL The speer JHP's were maybe 10 FPS slower.
13.0 gr H110 1375 FPS
14.0 gr H110 1480 FPS
14.5 gr H110 1550 FPS (Good Major load, but I had trouble finding H110)
13.7 gr AA9 1590 FPS
12.0 gr VVN110 1425 FPS
13.0 gr VVN110 1600 FPS (this was my old major load) Primers are a smidge flat From this point on, the loads are compressed a bit.
14.0 gr VVN110 1800 FPS Flat primers.
15.0 gr VVN110 gives @2100 FPS but causes case separations and bad primer flattening in anything that has been fired once. Probably pretty overpressure, but the gun really has negative buoyancy with this load. Blows the heck out of varmints (Rabbits, muskrats, Crats...) I would not use this load, but in the interest of completeness recorded it. I've shot 50 rounds of it, and it didn't look too bad with new brass. The second time around I threw them out after 2 shots, each time having a case separation.
124 gr Gold Dot JHP (.355) at 1.260 OAL.
13.0 gr VVN110 1510 FPS
14.5 gr H110 1525 FPS
147 gr Gold Dot JHP .355
13.5 gr H110 1495 FPS
My single stack version is a little slower velocity wise, but behaves the same as far as pressure. Have fun.
