I've loaded up some .40 S&W rounds with 180 gr copper plated flat nose bullets, 4.4 gr of Titegroup, and a OAL that is a little short averaging 1.11 when the book calls for 1.12. The max powder load is 4.7 gr minimum being 4.2 gr. Am I ok at 4.4 gr with a slightly shorter OAL or am I risking overpressure here? Thanks in advance.

you are fine.

you are fine.

 

Not to doubt you, but you're sure of this?

I'm running an identical load at 1.125/1.13 with the 4.4 and there's no issues or signs of overpressure. This is out of my glock and P226.

So at 1.11 do you think I'm risking overpressure or should I be good?

I think you should be good. I would test fire one or two and check for any signs of overpressure. If you don't see any, go for it.

I've been .02 shorter at the start load for 9mm because my HK required a shorter length to chamber correctly. It was fine.

Everything was fine! Holy crap, the satisfaction of shooting your own ammo is indescribable. I also loaded up ammo with 4.2 gr, and liked it better than the 4.4 gr. The increase in recoil from just .2 gr was more than I thought it'd be. Thanks for the advice guys.

Congrats!

 

I'm this close to doing it.

 

Which reload press did you go with?

Titegroup is funny with the way recoil compounds. Other powders are different

Nice! I remember back in August when I first tested the ammo I loaded, I was SCARED I screwed something up. But, I tested a few rounds, and though they sounded a little hot, there was nothing wrong. I know that feeling of nervousness you have when you're going to test your first batch XD.

If you are reloading you really need to pick up a, chrono.

Can someone recommend a decent one?

 

I'd lengthen those COL a touch.

Works great and under a hundred bucks.

That's titegroup for ya! Be careful with that stuff.

Agreed. The second batch I made, is measuring sliiiiiightly over 1.12 inches and are still able to fit into the magazine.

Yep, thats what I'm reading. A buddy suggested I try Power Pistol as well and see which I like better. But tbh, when I shot my 4.2 gr rounds, they were smooth as butter.

Perfect, thanks.

Like I said, you are fine.
