I am getting ready to reload and due to the need to ship most of the components I am trying to buy in bulk. That said, I don't want to buy 5k projectiles to find out they dont cycle in my pistol well.

I want to load 147g 9mm campro bullets. However, the only ones available are round nose, flat point. Has anyone put flat point projectiles through their shadow?

Thanks
 
Around 1500 rds for me, 135 gn LRN and about 500 rds Epoxy Coated LRN, not a single problem. Another 1000 rds, 125 gn LRN, also good. I prefer the 135 gn, less snappy. Also tried less than 100 rds, 145 gn LRN, very soft shooting with Win 231 and Titegroup for these weight group.
 
I run Berry 147 grain round nose in my Shadow , they cycle great. I know others who run the Campro flat points without a problem. It can depend on any mods you have done to your springs etc.
 
I'm somewhere around 400,000 of them through my various Shadows. loaded to 1.1 overall length
 
The bullets will work but you'll want to double check the OAL of your loaded rounds with the "plunk test". I know that with Berry's 147's around 1.12 was where the sides of the exposed bullet were far enough forward that it started jamming on the leade to the rifling and the rounds ran into problems of not wanting to go easily into battery. The Campro's might have a different shape to the nose ogive sides so you get away with it. But I'm thinking that 1.12 is pushing it and leaving little to no room for anything even slightly longer.

But that's where doing an initial 10 or 20 comes in. Also you want to load 'em up and shoot them over a chrono if you're really trying to get down close to the minimum. With 9mm the case volume is so small that even slight seating depth changes cause 30 or 40 fps variation in muzzle velocity.
 
I have a chrono lined up to use when I start testing. I have spoken with a few guys locally about their shadows and reloading. It has been suggested to start at 1.09 and end at 1.12. Make 10 or 20 bullets in each length and see what works best then pull the rest and reload to the desired length.
 
Get barrel out from the gun, make a dummy round without primer and no powder at say oal 1.13" and drop it into barrel to see if it hits rifling, keep seating bullet deeper till it doesn't hit rifling, then another 0.005" deeper and measure oal, that's what you get. Then start load development for powder charges.

1.1 OAL, 3.4-3.6grs of TG over whatever primer you want. Should give you 132-135PF
 
If you have a Veneer caliper to determine the OAL for a cartridge given bullet combination do as follows:

1. Remove the barrel from the gun.
2. Measure the length of the bullet you intend to use.
3. Drop the bullet into the gun and measure the distance from the base of the bullet to the top of the barrel hood where the case would normally lay flat.
4. Add 2 and 3 together and subtract 5 thousanths.
5. Check to see if cartridge will load in your guns magazine.

You now have the maximum length for that bullet for that gun.

or

for 9mm load 124 gr bullets to 1.1" and be done with it. I have never yet seen a 124/125 gr bullet not feed well at that length in any of my 9MM guns. I load my 147 gr Lyman 356637 bullets 1.056
