msg73 Posted January 19, 2016 Share Posted January 19, 2016 I ran Blue Bullets 147 gr over 3.2 grains of Bullseye loaded to 1.150" OAL yesterday. No hiccups at all. Luck of the draw on CZ barrels maybe Just started to experiment with these 147 FP bullets. Able to plunk test 1.15 in my shadow. So either different bullet profile or as stated above, luck of the draw on CZ barrels? https://www.ibejiheads.com/ Good luck...... Different bullet profiles. I've tried both Ibejihead and Acme 147 FP in my SP01. The Ibejiheads profiles allows me to load to 1.16", while the Acmes are 1.12". You can easily tell if you put the two bullets side by side.

himurax13 Posted January 20, 2016 Share Posted January 20, 2016 (edited) Weird, I have to load the Acme 147 to 1.095 on one of my Shadow barrels. I was able to load the Ibeji Heads to 1.135. Edited January 20, 2016 by himurax13 Link to comment Share on other sites More sharing options...
IDescribe Posted January 21, 2016 Share Posted January 21, 2016 That's not weird. That's exactly .04 in both cases. Link to comment Share on other sites More sharing options...

Slidestop Posted January 21, 2016 Share Posted January 21, 2016 I used 147gr Flat Point Blue Bullets seated to 1.14 with 0 issues. All good information. Can we also share which cz gun the data is for? (If it's not already posted.) Link to comment Share on other sites More sharing options...
huskerlrrp Posted January 26, 2016 Share Posted January 26, 2016 I've not reamed mine. I load to the pistols, including the Blue 147gr. For the record, the Blue Bullets are a little undersized for lead/coated at .355. Precision is lackluster in my CZ pistols, but I learned last week that they shoot well out of both my HK VP9 and Glock. I suspect the polygonal rifling handles the undersized Blue Bullets better than the land and groove rifling of the CZ. ACME is great. You seem already to have figured that out. Stick with that. Most 9mm brass will handle seating/insertion depth down to .300 (where the case walls start to thicken) without issue. You can actually go a bit deeper than that with beveled-base bullets. So you CAN load those ACME 147 right now if you like, but if you're set on reaming, you're probably better off not doing the load development twice. I'm getting different diameter measurements from my Blue Bullets. The following were done with a calibrated Mitutoyo sub micron digimatic micrometer. It appear Excel doesn't paste well here....basically 0.3562 average diameter.
