Coleman7 Posted November 21, 2015 Share Posted November 21, 2015 Hey guys I'm new here good to be part of the group alot of great info on here. I don't shoot comp at this time but I'm just working up some hot loads for my CZ P07. I'm loading 124gr XTP just looking to reach 1300fps the powders I have to work with are power pistol, hs-6, longshot, silhouette, sr 4756 and autocomp. I've worked up to 1210fps with longshot and hs-6 that's .2grs over max and at max of 6.5grs of power pistol is getting me around 1230fps. My main question is how far have some of you guys taken these powders I'm pretty confident by the looks of my brass that I can move several more 10ths above the max of power pistol possible way above. And several on the Longshot. Thanks for any data or advise Link to comment Share on other sites More sharing options...
atbarr Posted November 21, 2015 Share Posted November 21, 2015 Two questions, why? And do you have a Chronograph? Link to comment Share on other sites More sharing options...
Coleman7 Posted November 21, 2015 Author Share Posted November 21, 2015 Hey AT I'm just working up some fast loads just for the fun of to tell ya the truth. And yes I have a shooting chrony Link to comment Share on other sites More sharing options...
Coleman7 Posted November 21, 2015 Author Share Posted November 21, 2015 My P07 is simply a stock gun they have a good heavy slide. But I'm wondering if I should possibly move to a small rifle primer once I start loading beyond 35,000psi Link to comment Share on other sites More sharing options...

Flatland Shooter Posted November 21, 2015 Share Posted November 21, 2015 Does the CZPO7 have a ramped barrel? If not, don't do it. Link to comment Share on other sites More sharing options...

One, you seem to be tempting fate by just trying to get a load as hot as you can get it with little to no idea how bad of an idea that is.And second, it's advice, not advise!

Coleman7 Posted November 22, 2015 Author Share Posted November 22, 2015 Hey flatland shooter it is a ramped barrel most definitely a +p rated gun as well. Link to comment Share on other sites More sharing options...

tomfturner Posted November 22, 2015 Share Posted November 22, 2015 Search for 9 major you'll find what you're looking for. I don't know why you'd want to do that in a non-comped gun, but it'll be well over "published" data. Sent from my SM-G900V using Tapatalk Link to comment Share on other sites More sharing options...
Coleman7 Posted November 22, 2015 Author Share Posted November 22, 2015 Thanks tomfturner I've looked over many of the major loads and there far and beyond what I'm after I'm not wanting to run any of those kind of pressures. Alot of guys I've seen are pushing a 124 at and over 1400fps. I carry my P07 hunting with me every time I go I do alot of bowhunting and just looking for a good hot load but not overly hot if ya follow me. Mainly I guess I was looking to see where you guys have pushed these powders to and felt safe with the loads in a stock +p rated gun. Seems most folks jump to conclusions figuring they just started reloading or are trying to load a nuclear bomb lol. I'm not say you think that but I'm just trying to get a feel for what others have done with the powders that's it. I'll get it worked out thanks again tomfturner.

al503 Posted November 22, 2015 Share Posted November 22, 2015 I know you didn't ask about different powders but if you're going to go there, the safest way is to go with the slowest powders. 3n38, n105, or AA#7 is what I'd try. Also, load the cartridge as long as your mags/chamber will handle. Link to comment Share on other sites More sharing options...
IDescribe Posted November 22, 2015 Share Posted November 22, 2015 What's your Thanks tomfturner I've looked over many of the major loads and there far and beyond what I'm after I'm not wanting to run any of those kind of pressures. What makes you think you know what pressures they're running at? Why do you think you're not over 35k PSI already? What's your ".2 over max" charge weight? And what OAL are you loading at?

Coleman7 Posted November 22, 2015 Author Share Posted November 22, 2015 Hey Idescribe the max load I'm getting off Alliants page it's 6.5gr at 32,400psi I do belive and as far as my over max loading with hs-6 and longshot I'm certain I'm at or some above 35,000 I don't have a problem with running up to the 40,000 range but of course I have no way to know what my pressures are actually running. With these loads my oal was 1.10 but I've moved the power pistol up to 6.9gr and left my oal at 1.13 leaving as much as room as possible and still chamber well. I can squeeze out 1.15 I believe. If you guys aren't comfortable with giving any info that's fine I understand it's just that I've seen so many posting there loads and figure it would be a pretty good place to throw some questions out there.

Coleman7 Posted November 22, 2015 Author Share Posted November 22, 2015 Thanks al503 that's the info I'm looking for I know you guys have probably played with velocities and pressures more than myself. I've been reloading for 20yrs but mainly for bench rest rifles only loaded common handgun loads for the most part. Link to comment Share on other sites More sharing options...

Hi-Power Jack Posted November 22, 2015 Share Posted November 22, 2015 You can probably get up to 150 PF fairly safely - after that I wouldn't make hotter loads a steady diet. Have you considered buying a more powerful caliber? Link to comment Share on other sites More sharing options...
IDescribe Posted November 22, 2015 Share Posted November 22, 2015 (edited) You need to do a plunk test with the 1.13 you have already loaded. Break down the pistol, remove the barrel, hold the barrel crown down, and drop the bullet it in. If the bullet doesn't hit the lands, you should get a nice hollow plunk sound, and the bullet should spin freely in the chamber. If it doesn't plunk, won't spin, or will spin but with some drag, the OAL is too long. From what I've read from others, with the CZ-75, P-09, P-07, I am expecting you to need to load 1.10 or shorter. If you're loading 1.13 or longer and jamming the bullet into the lands, you're fooling yourself into thinking you're actually getting a pressure reduction for loading longer. You're going to get a pressure spike for being jammed into the lands or for setback, one of the two, or both. Remember that CZ pistols are manufactured in a country where JHP is not allowed, and they don't ream the chambers with JHP in mind, and the result is a generally short-throated pistol. Expect to load short. Also, remember that you're coming primarily from rifle. We're working with MUCH smaller internal case volumes, so anything you do has a more dramatic effect than it does with rifle. Also, don't look for pressure signs on cases in 9mm to warn you of anything. It's not a rifle cartridge, and your first "pressure sign" might be the pistol violently disassembling in your hands. Ultimately, the 124gr XTP is not the 124gr bullet with which to drive to 1300 feet/sec. It seats deeply into the case, like it's step-brother the HAP, which increases pressure. If you must do this, go with an RN that leaves more available case volume. Also, not sure why you're loading 9mm JHP for a woods gun. You'd be better off with hardcast or FMJ. Our dangerous furry friends have thick hides and heavy bones, and since you don't have to worry about passing through drywall into your child's room, why not go for the bullets that you can load faster more easily and will get greater penetration?It's not that people are reluctant to share load data. It's that they don't have load data for what you're doing because it's not a great idea to begin with.

kneelingatlas Posted November 22, 2015 Share Posted November 22, 2015 Of the powders you mentioned, HS6 is the one to use; I don't recommend using rifle primers for what you're doing since they can lead to breech face erosion and only hide to signs of high pressure. HS6 and SPP will get you there, just use a chrono and work up to where you want to be. Expect to wind up just over 7gr. I don't have any experience with the P07 chambers but I've gone as high as 7.7gr of HS6 in a CZ75. No a side note, are you expecting to encounter two legged predictors in light clothes while hunting? Even at 1,300 FPS a 124gr hollow point is not what I would choose to defend myself against dangerous game. Link to comment Share on other sites More sharing options...

Coleman7 Posted November 22, 2015 Author Share Posted November 22, 2015 Thanks for all the great info guys. Hey Idescribe no worries on the on the oal I always check my oal in relationship to the lands and you are correct CZs are all at least the many that I've had shallow throated turns out after loading last night and checking everything oal of 1.10 is just touching the lands. So I've backed up to 1.09 which plunks and turns freely. So this leaves me very little room with the power pistol I loaded up some 6.9gr at 1.09 this leaves a very small margin of case room between the bullet. I've had this problem with the 115gr hap great bullets but the ojive calls for a deep seat. You are correct for sure on going with a RN like a gold dot for a hollowpoint. I've loaded and shot 1000s of 124gr campros hp love them they worked out great in the oal area. Edited by GrumpyOne for content. Link to comment Share on other sites More sharing options...
