F Nster · June 3, 2010, 08:48 PM

Hello All.

I am new to the forum and see there are a lot of people on here with good info. I am starting into reloading and trying to be as safe as possible, Reading books, internet, Ect. I own a few reloading books but have yet to find a recipe and OAL for my bullet and powder. Anybody experienced with .40?
Bullet- 180 Grn. Horndy FMJ FP
Powder- Bullseye

This is from the Alliant website. As long as you reduce the charge 10 percent and work up the different bullet shouldn't make a lot of difference.

Be very careful regarding charge weight with fast pistol powders in the .40. It doesn't take much over with the fast pistol powders to end up with scrap metal versus a pistol.

All the Best,

I most highly do NOT recommend Bullseye in the 40 S&W; I recommend Alliant Power Pistol.

But safe is 3.8g Bullseye (can go to 4.2g) / 180g / OAL 1.130".

I have loaded 180gr Rainier Lead safe RNFP's with Bullseye. I used 4.5gr's of bullseye with Winchester Primers. Mixed brass. COAL 1.120". F.P.S. of 1010 out of a 4" Springfield XD. Lead safes are a plated bullet though, not jacketed.

I've been shooting 180gr TCFP lead with Bullseye for thousands of rounds with no problem. 4.2gr gives me a manageable load with moderate recoil, not "snappy" at all.

So why do you recommend against it?

A whole bunch of my daughter's friends have run my 180 JHP's through various manufacturer's weapons - but I'm rolling 5.4 grains of Unique now, however - I have tried Bullseye 4.3 grains, but liked the Unique loads better.

I'm running Montana bullets - the 180 JHP - which looks awesome and is providing some good accuracy as well.

God bless and good shooting.

Because Bullseye leaves no margin for error, particularly when using fired cases.

Why does Bullseye not leave a margin of error?

Is it because of the light load required that the +-0.1 grn is too high a percentage (> 2.5%)?

Or is the statement that Bullseye is particularly unlinear in it's pressure to volume ratios?

Just curious. I've been loading my .40 and still using Unique which I started with and am baselining from, however PowerPistol and Bullseye are also readily available in my area.

Thanks

Bullseye is faster than the other powders mentioned, so a lower charge that reaches a given velocity operates with more pressure near the breech and less near the muzzle. For a given velocity, you have a higher peak pressure with the fastest powder you achieve it with. That's universally true for all guns and cartridges. So, it's that lack of extra headroom for peak pressure in the event of a high-side charge that makes fast powder loads more critical if they are near full power. It also makes a higher increase in peak pressure if a bullet gets set back into the case than something like Power Pistol will.

I don't own any measure that throws Bullseye or any other flake within 0.1 grains. A 0.4 grain spread is more typical. Power Pistol, on the other hand, can be metered within 0.1 grains by steel drum measures and probably by some others I haven't tried. If you are individually weighing charges, that's different, and Bullseye is fine provided your crimping practice insures no setback can occur on feeding.

A powder near the speed of Bullseye that meters well is 231/HP38.

Not only for the answer, but the detailed understanding that goes with it.

You're a generous guru.

WESHOOT2 · June 17, 2010, 07:23 PM

The concern from even minimal setback.......
I use Bullseye in the 40 SA&W with new sized cases only.

It can provide superior accuracy with 200g bullets.

But for making 'normal' ammo (or cop ammo) I chose Power Pistol.
