Apologies if this has already been dealth with. I'm hoping for a quick answer cause I'm kinda in the middle of it. I'm reloading 45 ACP 200g JSWC using HS-6. I expect my max load would be 9.0 gr BUT ??

I've got all sorts of reloading data for .45 ACP 185g JSWC, which allows for 9.5gr of HS-6 Max, but nothing for 200g JSWC.

Question: Can I use the posted data for .45 ACP 200g JHP?? This allows for 9.0 gr of HS-6 max. Waddya think ?? :confused:

I think the powder volume goes by the weight of bullet instead of the type of bullet? Hey, I'm a rookie to this reloading business, so don't take my words before checking with other guys! :)

Didn't mean to hijack your thread, but I've got a question here also for 45 ACP 200gr JHP too. What's the OAL for 200gr JHP? The Lyman manual said it should be 1.1736", I used 1.1875". But I did get misfeeding for 2 or 3 times out of 20 rounds while shooting at the range. There're some guys using 1.22" and they were fine.

Any comments will be welcome!

Hodgdon, Lyman and Lee all list 9.0 gr for max load with 200 gr jacketed using HS-6.
~950 fps with 16,400 CUP (Lyman's says 17,600).
Hornady was the odd one. It says 9.8 gr max ~1000 fps.

You know the Lyman's COL.
Lee & Hodgdon say 1.155 COL for 200 gr jacketed.
Hornady says 1.230 for 200 gr HP-XTP

I seat all of mine (SWC, FMJ, lead, jacketed....whatever) to 1.230 and have had no probs.

(E) :cool:

I've adopted 8.7gr as Max load after it was suggested to me that, to a degree, shape matters. The 185gr JSWC is listed at 9.5gr of HS-6 Max.

For the 200 gr JSWC then, I calculated the Max load for HS-6 as follows:

9.5 - {(200 - 185) / 185} x 9.5 = 8.73

In other words I reduced the powder charge by the same % as the bullet weight increase for the JSWC. I'm pretty confident that 9 gr would be ok too but 8.7is more conservative,,,like me.

Nonetheless, I'm guessing and grateful for everyone's ideas on the subject.

BTW I've had COL issues too and wound up with COL being longer than recommended in the manual(s). I made up a dummy in the best length I could achieve and cycled it through my pistol,,,wtf it works !

I'm beginning to think that they hire the same people to write up reloading tables that they use to write the horse#### on paint can labels. Their arses are covered. Its not possible to duplicate their conditions so you wind up using the product out of spec.

I just started reloading and had the same feeding problems but I had 1 misfeed per mag.
A friend suggested that I taper crimp my reloads and since doing this I have not had a misfeed in 100 rounds and I never changed my OAL .
 
An easy way to determine the OAL for any bullet combintation is as follows: First measure the length of the bullet you intend to load. Remove your barrel from the gun and drop the bullet in to the chamber. Measure the length from the base of the bullet to the top of the chamber. Add the length of the bullet to that measurement. Back off a few thousands and you have the OAL your cartridge shoulb be for THAT bullet.

The olgive of the bullet is part of what determines the OAL of any given bullet. Some bullets look alike but have different olgives. A bullet with a fatter olgive will catch the rifling before one that is thinner and perhaps a little longer.

Hope I have described the method clearly enough.

All .45acp cartridges require a slight taper crimp. I run mine to .470, which is just enough to remove the belling. The .45acp bullet is retained by case friction and really only requires the belling to be removed.

Stay Safe
 
Been to the range.

8.7 gr of HS-6 using 200gr JSWC 45 ACP produced velocities as high as 1054 fps from my HK Mark 23.

Ended up making major PF using just 7.2 gr loads.
 
If you look at the lyman recipe vs. the other ones they allow for more powder for the longer COL. Shortening COL will increase pressure. You can use the same amount of powder for the the same weight bullet provided as above you do not end up decreasing COL due to bullet profile. If you don't have a listed load for the bullet weight you want to use start with the next heavier bullet weight on your chart and you'll be O.K. Work it up from there. Any load you use should be reduced from the max listed to begin anyways!
 
Good loads for the Jacketed 200 grains SWC can be found in the Hornady reloading manual. They make JSWC with the same profile as the lead H&G 68, the most common 200 SWC type. If you ever want to try another powder, 5.0 grain of Bullseye behind a Hornady 200 grain TMJ ( their designation for a your JSWC ), this make major and it is a great - accurate load. Since it is a faster powder than HS6, it will cycle any gun. Burn a bit cleaner too. Nothing wrong with HS6.
