Conflicting load Data

[Dustinthewind]

I am loading .45 ACP with 185 grain Hornady XTP's. I was planning on using Titegroup. I am wanting to push the out at around 1000 fps or better. Hornady load data shows 6.6 gr of Titegroup as max load with 1050 fps. Hodgdon data lists 5.5 gr and 906 fps as max. Sierra shows 6.2 gr as max for their 185 gr hollow point. Has anyone tried 6.2 or 6.6 grains of Titegroup in the .45 ACp?

If I wanted to get to 1000+ FPS with 185 Gr. XTP's I would go with something slower than Titegroup. At least AA #5 and slower.

The only powder Hodgdon shows pushing a jacketed 185 Gr. bullet at over 1000 FPS is Longshot, with HS-6 and Universal Clays coming close.

You should look at the weapon used, barrel length/rifling, case, primer, and bullet used to develop the data. Any variations in these components and weapons can strongly change MV.

So before you go off halfcocked, by saying the data is in conflict, look over the data again.

I can get the velocity by using Unique, which I like, but it doesn't meter well in the Lee powder measure on my Pro 1000. Walkalong, How does AA #5 meter? Or Longshot? I can meter the Unique with my Pacific measure but then I have to manually charge every case.

Test firearms are Gov't Model 1911's 5" barrel 1 in 16 twist Primers Winchester WLP and Federal 150.

How does AA #5 meter

AA #5 is a fine flattened ball powder which meters Great. Never used Longshot.

Accurate shows the 185 Gr. XTP and 10.2 Grs. AA #5 at 1.210 O.A.L. for 1102 FPS and 19,900 PSI

Accurate shows the 185 Gr. XTP and 13.0 Grs. AA #7 at 1.210 O.A.L. for 1093 FPS and 18,000 PSI

Accurate is usually a bit liberal with their velocities, but you can expect to get close to this.

They used a 5" barrel and Fed 150 Primer.

Start load for AA #5 is 9.2 for 970 FPS.

Start load for AA #7 is 11.7 for 962 FPS.

Both Longshot and AA5 will meter very well.

If I were going for that kind of velocty, I'd check into Alliant Power Pistol.

Thanks for the replies! I think I will give AA# 5 a try. The Discrepancy I was alluding to was the charge weight 5.5 max from Hodgdon data vs 6.6 max Hornady data.

Powder companies are almost always more conservative with their loads than the bullet manufacturers who are publishing for their specific brand of bullet. Hodgdon's data at 5.5grs is only listed at 17,000 CUP's. Standard pressure in CUP's for the .45 ACP is 19,900 CUP. As to what that translates to in a linear PSI scale is unknown but is is a good safety factor below the maximum standard pressure.

there are better chioces of powders than Titegroup. its a low volume high intensity powder, try 700x,800x, red dot, blue dot, but Titegroup is not your best choice out there

I use power pistol with 185gr Nosler HPs at ~1000 fps, with charges slightly under max. It meters very well and seems to be as good as unique/Herco for this type of load.
