Preferred bullit weight for IPSC?

Well it appears the BB course is going to go ahead in late Aug or early Sep.

I just got my new gun and gear, and put a few hundred rounds through her,
Seems at 25 yards I need to do the six o'clock? Aim to hit my target.

Using campro 115g bullits/tightgroup powder.
CZ shadow 1

I've ordered another 1000 115 campros and am now second guessing myself.

What bullit weights do you prefer and why?
Will I even notice a difference?

In regards to IPSC :)

What do you folks think of my POA/POI?

I've always used 147s but I think I will go back to 124s when I run out.

I still have to work up the loads but my guess is they might be more accurate out of my guns
 
Nice. You'll have tons of fun. I'm currently shooting 124gr Campros but going to experiment with 147gr, not so much for the paper but making sure I knock down steel. With the 124gr pills at around 127-128PF, I'm using a 10lb recoil spring and it's pretty flat shooting. With the 147gr, I'll be trying an 8lb recoil spring.
 
Is the weight more for accuracy or being more capable of knocking over,steel plates?

Ifs it's accuracy only, I find the 115,s great.
 
As far as I know IPSC poppers are set to drop for 115gr (could even be less). So you should be fine with whatever your gun likes. We usually just run 115gr or 124gr (whatever we can get cheaply). Never had an issue with a popper not falling, except if I don't actually hit them....Just my 2 cents
 
Thanks,

Any thoughts on my POA/POI.

My last CZ ,I had to cover the target ,with my front sight,to hit it.
This CZ,I have to keep my target ,just above the front sight,to hit it.

Also the trigger seems really light on my new CZ.
Not complaining:) just curious,as to why.

Have you done the math? I would be surprised if there is any positive appreciable difference in kinetic energies between 124s and 147s at normal IPSC distances. In fact, I would have thought the advantage in kinetic energy goes to the 124s at IPSC distances (just a guess though)

I use 147 grain in 9mm because it allows me to use less powder, get a slower FPS and still meet power factor. In my shadow and my Glock I felt less recoil and got back on target faster.
But there is a trade if you play close to minimum power factor. I find plates fall slower and poppers may not fall unless you get a nice centre hit. Which is how poppers are supposed to be. With a slower bullet speed the gun can get quite a bit dirtier too.

115 grain ammo is perfectly fine for IPSC. It really is. I will shoot whatever I can get my hands on when I have not loaded any 147.
The CZ is very accurate with it too.
Don't get too caught up in chasing the perfect IPSC load yet. With proper technique and many hours of training you will shoot well no matter what. But eventually you will notice things you like about different loads and pick a favourite that works for your needs.
 
124gr or 147gr. both keep you under supersonic for making power factor. Which one just depends on your preference. I prefer 147gr but some people prefer a little more speed in their slide and so they use 124gr. You won't find anyone using 115gr on purpose.
 
HI; I cleaned up all the dropped ejected rounds after our IPSC match. Pulled bullet were one 115, ten 124/125, and one 147 grain bullet. I was advise 115 have a lot of muzzle blast and 124 less so. For the BB course is not any power factor. If you do things fast and right you can pass a BB course with 200 to 300 rounds. Know your gun and how to shoot it.

The Shadow seems to like CamPro 124gr. HP Titegroup 5.0 @ 1.110OAL. It will get you about a 130PF.

Holy hot load. Hodgdon rec max is 4.1. You load 5gr of TG behind a 124gr pill, oh, you're hitting 130PF for sure and then some. 4.1gr of TG got me 135PF out of my Glock. I'm running Campro 124gr behind 4.0gr TG.

I just went with what the other match shooters were telling me BUT you peaked my curiosity and I just ran the numbers through a calculator... I'm surprised. Running both close to 128PF, the amount of joules is just slightly higher on the 124gr over the 147gr. I guess I'm not getting more knockdown power as I originally thought. Damn, you learn something new everyday.

I guess the pros of 147gr is less powder and slightly reduced recoil but cost savings of using less powder is offset by the cost of more expensive pills. Well, I've got 500 pills to experiment with. :p
 
I've only shot IPSC for about 4 years so I am a novice and take this with a grain of salt, but most of the production shooters seemed to use 124 grain or 147 grain.

I experimented with 124 grain which I found a bit snappy and switched to 147 gr Campro over 3.4 grains of TG and didn't look back. Less recoil, less powder, very easy to make power factor and more accurate for me with my SP01 Shadow. THe Glock 17 seems to like that load as well.
