    i know fred can help on this one. i usually load a 230 fmj with 6.3 grains of unique. it seems fine in my glock 30. now i have picked up a box of hornady 230 grain xtp's. some of the websites i checked out had loads using up to 7.2 grains of unique with a 230 grain fmj. man that seems really warm! i was just wondering if i could work up to even 6.6 grains unique with the xtp. anyone know the aprox pressure of this load?

    For the 230 grain XTP one manual shows 5.1 to 6.1 grains of Unique for 850 fps and one manual shows 5.8 - 6.4 grains of Unique for 880 fps (5 inch barrel?) loaded to 1.230". 6.0 of Unique is not a bad load. The XTP will be hotter than a round nose FMJ bullet with the same powder charge.

    I have a Hornady manual that shows 7.3gr of Unique under 230gr FMJ will fire at 900fps:wow:

    i have an old hornady manual that also shows 7.3 unique and a 230 fmj
    i just shot 5 rounds of the xtp with 6.6 grains of unique and it's just too hot.
    at least out of my glock 30 badly bulged brass with a line on it. you can tell the brass was stretched. very accurate. sooner or later i know a piece of brass would give way with that load and my glock 30. i will be using about 6.2 grains and no more. unless i get a hold of some thicker brass or a stouter recoil spring if that would even help

    900ft/s is hot. I stay in the 825 range. Are you making these for practicing or actually HD/carry? Most folks I come across use factory loads for the latter. But it's imperative to practice with at least equivalent loads.

    Garander, I'm using 5.7 grns of unique under 230 fmj and get carbon on the case after firing through my G30. I suspect the case isn't expanding enough in the chamber. Do your cases exhibit the same with 6.3 grns of Unique through your G30? I've worked up a few loads to 6.3 grns, just want to check if I'm going in the right direction.

    no hogpaul i dont get much carbon on my cases with the 6.3 grain fmj load.
    i think most guys say some carbon on the case mouth is not that big a deal. i know bullets fit my glock 30 chamber much looser than my series 70 1911

    I've been using 6.0gr of unique with 230gr fmj through my 1911's and my g30 for awhile now. Shoots cleaner and is accurate. Started loading 40 s&w with it too. My 2¢.

    Make sure your load data is up to date. Unique is a faster powder than it was some years ago. Years ago the standard 230 grain FMJ load was 6.5 grains of old Unique. The current Unique will about match that old load with about 6.0 grains of Unique.

    Even w/ the new Unique, 6.5gr under a 230grFMJ @ 1.255"OAL runs just under 900fps. I have run the same load under a Win 230grjHP @ 1.250" & it is still pushing right up under 900fps in a 5"bbl. I don't know the pressure, but cases look fine in a 1911 or XD. With the XTP, it's going to be bout your OAL. I am not sure you can get them much longer than 1.230". I'm not sure I would trust any data running over 7gr & then I would want to be at the longest OAL I could get. Some of the older manuals go there & a bit beyond, but I only use older data w/ older powders. Whether the powders have changed or not, it's just not prudent to expect 30yr old data to work the same w/ todays powder.
    Running them hotter will certainly be in +P territory by most printed data sources. Just not need IMO. Run the 6.3gr-6.4gr range & call it good. BTW, if you are handloading for SD, consider the 230gr RGS or GoldDot in 230gr. With the XTP, I prefer the 200gr going 900fps+. It digs as deep as most other 230grJHP w/ less recoil.

    Not to highjack the thread, but what is this an indication of? Too light a charge? I have some reloads that I have been using up in a pre-Kahr Tommy gun that I recently tried in my new G36 and I got a triangle shaped carbon streak down one side of the brass, so i am curious.

    Thanks,

    yes the streak down the side of your case certainly can be to light a charge.
    i would think the glock with it's sloppier chamber might be more prone to this.
    as i have said my 1911 chambers are a lot tighter than my glock 30's

    hey fred here is two fired cases with the bulge after using 6.6 grains of unique with the 230 gr xtp 1.233 oal. cbc once fired brass. not all of the cases bulged but these two did. charges were weighed. those two slugs barley made it into the second phone book. i might try some starline brass with 6.4 grains. i want something fairly stiff for carry

    Usually the low pressure smoking or carbon covers about half the mouth of the case or more. It can be low pressure rounds or an oversize chamber or both.
    Ouch, definitely crank those down a bit. It could also be the CBC brass. It looks like you are testing in dry phone books. Dry paper is really tough on any bullet. Soak those phone books for at least 8hrs & then shoot them. You'll need at least 12" to capture most JHP & can test as many as 6 bullets in one stack. The XTp is not an expander, 62cal is quite large for any XTp. It's why I like the 200gr. Easily drive them to 900fps for good expansion & faster follow up shots. I carry the factory 200grXTp in my lt.wt. 1911PD.

    Unique is not faster than it was in the old days. They still have a sample of it from 100 years ago they use as a control from time to time to make sure it is still within spec.

    I'll see if I can find the link I posted a few eeks ago on the history of the original Unique and some other powders.

    thanks fred. thanks guys for the reply's i will be cranking down my load with the xtp's. i fired 5 with 6.3 grains of unique with new remington brass and only one of the 5 had a bulge and not as bad a bulge as the 6.6 grain load. still a lot of recoil! man!
    i can see going down even to 6 grains. i know, i screwed up. i am actually working down a load!

    Hornady 230 XTP's seem to create a little more pressure than some other 230 grainers. Bearing surface or jacket could cause this. With Hornady 230 XTP's and Unique I'd not load higher than 6.0 to a maximum of 6.2 grains using Hornady's recommended oal. Your brand cases or primers used could change the maximum. Now with the Remington 230 Golden Saber with it's minor diameter with a driving band, you can go up as high as 6.5 grains of Unique without pressure signs like the cases in your pics. I had some 1985 Unique that I compared to 2000's dated Unique and velocity with the same load was nearly identical, within 5 fps.

    You may find that carrying max loads provides very little benefits while at the same time adding unwanted recoil.

    If one shot stops, or even one hot hits in a social encounter were the norm the phrase 'follow up shots' never would have been invented.

    Just my opinion, based on a little bit of experience.

    You are so right Mr. Jack. The add'l. 50fps or so doesn't add much to the bullet perfromance & the recoil, especially in smaller lt.wt. guns just causes slower shots or missed shots delivered w/ the same speed, at least for me, & I shoot a lot of 44mag, so it's not like I am recoil shy.:dunno:
