| I am loading up some hornady xtp 230 grain under 6.0 grains of unique. I don't have exact load data for these rounds and am going off of what I worked up with 230 rn rounds. I plan was to use an oal of 1.25 but it looks as if the projectile is sticking out a lot more than my rn projectiles. The min oal that the lee book says is 1.19 and my Lyman book says 1.275. Does anyone load with this combo and what do you use for an oal?? |

I used titegroup for the first thousand. It's fine, and the accuracy is great, but I find a fair amount of powder residue on my forearms from shooting this load.
I'll probably use a VV powder for the next 1K, as I'm really digging that for the 185 gr. JHP (Nosler) load. I'm away from my reloading bench about 11 months of the year, so I do a lot of shopping for reloading components and not nearly enough reloading. My basement if filled up with components waiting for me to get back stateside. There are other much more experienced reloaders who will be along shortly to help you out. Good Luck. |
| 1.230" is Hornady's recommended oal and it does well in Colt's and Glocks at that length. Hornady says 5.8 grains of Unique gets 800 fps and their maximum at 6.1 shows 850 fps. Your load at 6.0 grains is an often recommended load. I shoot both Unique at 6.0-6.3 grains and Accurate Arms #5 from 8.0-8.2 grains in various brass with both CCI 300 and RP 2 1/2 primers. Both Unique and AA#5 works very well in the 45 ACP especially with the 230 XTP. |

bso,
I could give you an oal out of a Hornady manual, which someone will likely enable you with directly anyways. I'd rather help equip you with the where-with-all to sort these type questions for yourself. Each bullet has a straight bearing or bore surface. Coming off the straight wall bearing surface a bullet curves or is angled to the tip. This curvature or angle is known as bullet ogive. A good seating rule is to seat your bullets with a distance no less than 1/32" from case mouth to beginning of ogive. Another consideration is accuracy, usually the longer we seat a pistol bullet we increase accuracy. Limiting length is your weapon feed channel, starting with magazine and internal geometry within your weapon. My first rule to cartridge manufacturing is a cartridge must feed in order to fire. If cartridge can't feed everything else doesn't mean diddly. You would be well served to visit Missouri Bullet Company website. Get familiar with their various .45acp bullets. The one to pay attention to is a 185 grain, lead button nose semi-wadcutter. Compare with semi-wadcutters. Semi-wadcutters generally seat at 1.240 to 1.245. Button nose semi-wadcutter has a much shorter nose. It seats from 1.10 to 1.20. If you tried to seat a semi-wadcutter at 1.20 you'd have shoved the shoulder or bullet ogive inside, below case mouth. Remember the 1/32" rule. When loading a new bullet I seat a bullet in a non-charged case. No primer, no powder. I seat long and lower until reaching a point of maximum feed-ability with my gun. Then reference your bullet weight in a manual. I start my charge weights generally mid-range with .45acp. Proper procedure is to start low and work your way up. A Hornady manual is a good idea too. Load Safe, dc. |

I'm really digging that for the 185 gr. JHP Nosler load. Look at a 185 grain Zero, then compare to Nosler. Don't remember who exactly gave me the information. I just vaguely recall the source being the horse is all. Kinda like better than going to the horse's mouth. As I recall, Nosler designed a portion of a plant around a concept much like Zero's 185 grain. 
Anyhow, the horse. I mean my source said, after showing me lots of test targets that his. I mean, Zero 185 grain performs very well with N310. The horse's . I mean my sources test targets and conversations were eye openers into how manufacturers do load development and how closely this particular horse. I mean source worked with powder companies. Interestingly enough I've shared some parts of that conversation without sourcing the horse, out of respect to my source. It's interesting the folks who need to absorb industry insider tips the most blow them off. What's that sayin ? " You can lead a horse to water, but you can't make him drink." By the way. Start at the bottom of VihtaVouri charge weight range. When working this load up, I settled on the charge weight as suggested to me. Still, I worked my load up just the same in 3/10th increments before working to 1/10th increments for my 1911s. My accuracy charge weight was on the low side. Power factor weight was higher. |
| 1911, what's your opinion of hp38 in 45 loads?? I have a plethora of that stuff an may use that next. Btw thx for the info. U guys are always a wealth of knowledge! 1911 thx for the explanation now I feel comfortable loading some other rounds I've had for awhile |

Glad to help bso. Have never tried HP38. Ammunition companies do load workups everytime a lot number changes. They're buying powder in bulk and it varies from lot to lot. We load cannister grade which is very consistent lot to lot and we pay a premium for it too. Munition companies have to work up each lot. Starting at the bottom and working up. My source does his load work-ups using test barrel with targets set 30 yards out and tests way more than 10 bullets at a target. More like a hundred. Afterwards he goes with the tightest groups within acceptable pressures. The test targest I was shown all grouped under 3". For a 3,5 or 10 shot group you might not be impressed. For a hundred shots hitting with that type consistency from a hot barrel. Yea, that's good enough.
Just work your HP38. Try various charge weight with multiple oal. You'll find a combination that groups. Regards, dc. |
