so what length you guys load the above bullets too? I'm at 1.120" right now, and still have the bullets touching the rifling, I used to load my Frontiers and Montana Gold much much longer. My Speer Gold Dots that I use in competition are loaded to 1.130-1.135". I've actually had to change my load with the Campro's as I have to seat them much deeper in the case than any previous 147gr TMJ/FMJ due to pressure signs on the primers and case.
this is for shooting out of my new Shadow. My Stock II had no issues with a longer round, around 1.160-1.165", but the Shadow won't even feed these out of the magazine reliably.
 
I was loading Frontier 147's for my Glock17 at 1.125. I notice the CanPro 147's are about 10 thou longer than the Frontiers. I was just going to split the difference and load the Canpro's to 1.130.

That was until I found that the CanPro's were sticking in my Lee seating die and would not seat in the case. I guess I need to ream out the die body a hair or turn the die body way out and screw down the the seating plug.
 
I'm not loading my own, but my BDX ammo with a 147gr. truncated FMJ is loaded at 1.135". I think Kurt mentioned the 147gr. are a Speer bullet, but that is not certain.

Guys have an idea what load would it be with the Bullseye powder?

Using 147g Campro RN plated of course.

I usually use Titegroup but it's BO and I need the ammo shortly for an event.

Cheers.

And I usually load my rounds to 1.15 OAL.

all loads are available on handloads.com
I don't rely much on the info they give, but rather go directly to the source they quote. They have "guest" sources, which I basicly never read and then sources that are bullet/powder/ammo manufacturer, most of the time you can get the info directly from them.

Also usefull on handloads.com is the reduced load calculator, it's a gross estimation, but it worked for me within ±0,2 grain.
Say you want a 800 Fps load to achieve correct powerfactor, dial in the max load and fps, and put in an arbitrary lower powder charge, it'll give you the adjusted FPS. Then when time allows, test with a chronograph (I understand you're in a hurry now)

Just a note of caution.

Be VERY careful with Bullseye, and heavy bullets. Do NOT shorten LOA because pressures can jump tremendously with seemingly minor shortening of LOA. If in doubt, load as long as you can.

Also, remember that muzzle velocity does not equal peak pressure. With a fast powder like bullseye, you can have so-so velocities, yet enough peak pressure to destroy a gun.

With fast powders, the peak pressure will occur about the time the bullet has travelled about 1/8" (yep, that is correct, the bullet has hardly moved and the base hasn't even cleared the case)

Ok got a box of 147 g Campro 9mm last day...

I have the same issue then you guys now whit my HKp30.

I usually load at 1.15 the 124g but with this big bullet I need to seat them at 1.10/1.11 to them to fit just on the riffling.


That seems to be quite short!!!! In the book they say it should be 1.165!!!!

I reload at the minimum load chart for 147g at 3.4g of Bullseye powder. I am thinking of going down to 3.0grain of powder and chrono it.

What you guys think?

Any danger to seat them that short? Even under a light load? Any ideas?



Cheers.

Quickload (SAAMI 9mm = 35000 PSI max):
3,4G Bullseye + 147G Campro + 1,110" = 28885 PSI & 972 FPS
3,6G Bullseye + 147G Campro + 1,110" = 32718 PSI & 1016 FPS
3,8G Bullseye + 147G Campro + 1,110" = 36931 PSI & 1057 FPS

A good comparison would also to take one loading, say the 3.8 and change the OAL, both longer and shorter, and post what happens to the pressures.

You (and others) will find the results very interesting.
 
You're giving me work SandRoad !

3,4G Bullseye + 147G Campro + 1,108" = 29193 PSI & 974 FPS
3,4G Bullseye + 147G Campro + 1,110" = 28864 PSI & 972 FPS
3,4G Bullseye + 147G Campro + 1,112" = 28543 PSI & 971 FPS

3,6G Bullseye + 147G Campro + 1,108" = 33104 PSI & 1018 FPS
3,6G Bullseye + 147G Campro + 1,110" = 32717 PSI & 1016 FPS
3,6G Bullseye + 147G Campro + 1,112" = 32340 PSI & 1014 FPS

3,8G Bullseye + 147G Campro + 1,108" = 37381 PSI & 1059 FPS
3,8G Bullseye + 147G Campro + 1,110" = 36929 PSI & 1057 FPS
3,8G Bullseye + 147G Campro + 1,112" = 36489 PSI & 1055 FPS

Thanks. It was just to point out that very minor changes in OAL don't do anything for velocity but can have a very major effect on pressure.


BTW, I do have QuickLoad, but it was on a computer/HD that crashed and I haven't reinstalled it yet. :redface:
 
Similar but a little less than 231.

I use 231 with 124's and Unique with 147's.

Neither one is too dirty to run all day shooting without cleaning.
500+ rounds.
When shooting big competitions, I clean at night but just to be safe.
Never had an issue with several 1000 rounds in between cleaning.
