There is another thread that I responded to but since it's over a year old it won't let me. Really, what's the use of the search if you can't discuss a relevant topic? :confused:

Anyway, here's what I was going to post.

I used them with the 185 Gr XTP's

Started with 5.0 worked up to 5.7.

4.5 will still cycle my glock fine with stock springs.

I know this is old but I'm a little confused about what I'm reading online vs what alliant is telling me to do. I'm also using a 185 gr XTP and their site is telling me to use 6.4 grains.

6.4gr sounds like a lot to me as well.

Here's the real issue IMO. Manuals nowadays are so lawyered down to protect themselves from idiots most of them stick to very safe parameters. Most powders have a much larger range than most people think.

It's not uncommon for a new reloader to pick up a modern manual, load a round, and then discover that the round won't function their gun and doesn't feel like store bought ammo.

Today's loads are weak. The powder is capable of more almost all of the time.

That being said. I've never put 6.4gr of BE in any case and see no need to load that hot. You kind of need to question a source that only gives one load instead of a starting and ending point. I mean, come on, how hard is it to give us a little more data. Especially with über fast powders like BE you need to be extra careful of maxes and bullet setback. But BE is also one of those powders that doesn't get exponentially crazy the hotter you go. Most powders get spikes toward the top making loading hot dangerous.

In conclusion I'd start way lower and work the load up. Pick up any manual and I'm sure they'll start way lower than 6.4gr.

Here's the source, right from the cow's mouth. I find it a little odd too that they don't give a starting point.

I think you can use the Alliant data. IIRC XTP's have a little longer bearing surface than GD's, so definitely use Alliant'sdata as intended, that is, 6.4gr is max, drop down 10% and work up slowly. XTP's are longer than GD's, so I would probably bump the OAL unless you had to load that short.

Oh, I believe you. The only explanation I have is that BE must behave really nicely loaded hot. It's what we as reloaders would like to see every powder mimic. But in reality most powders spike and can be very dangerous at peak levels.

I usually stray away from fast powders with little volume. But BE is one that really isn't all that dangerous. Not like TG at all. More guns have been kaboomed with TG than any other powder I'd bet. The only thing bad about BE is it's so dirty.

The oldest load in the book is 5.0gr of BE under a 230gr RN. Great round.

6.4 BE behind any 45 bullet is too hot. I recently had 5 out of 100 cases ruptured in the middle of the body. These are the only 5 after 1000s of 45 rounds loaded and shot over the years. Like Bill said, bear surface has a lot to do with the pressure from the same load. Use the right load data for/from the bullet manufacturer if you can get it. If not, work it up slow and watch for the press signs.

That load sounds about right, but sounds like a hot load. I'd start at 5.5 and work up. Don't start at 6.4.

The Load that I used was 3.2 grains of Bullseye with a 185 Nosler JHP. Thru my gun off of Bags it would shoot less than 1" at 50 yards. My gun is a 6" Build with a Kart Barrel. Deadly accurate!

Yeah, but you are probably running a 1911 with a 12 pound recoil spring. He's running a Glock with a 17 pound spring.

Hornady manual for 185 XTP wit Bullseye states a min of 5.3 and a max of 7.0 gr for velocity of 1050 fired from a 5" Colt Gov't. When I worked up my load for my 5" barrel SA 1911, I used a range of 5.3 to 6.6 gr Bullseye and settled on 6.2 as my accurate load with avg velocity of 1036 fps. The 6.6 gr rounds were a little hotter, but no issues with brass or recoil and just as accurate for me as the 6.2 gr. My oal for this load is 1.230 and I used Wolf primers which gave me a steady ~50 fps faster then Hornady data and components.

IIRC, they have a blanket statement to reduce by 10% for starting loads (unless otherwise directed...some powders aren't to be reduced by much).

My target loads are 200-205 cast with 5gr BE.

I just did a test load for 45 XTP with bullseye on tuesday

I did 4.4, 5.2, 5.8, 6.4gn

my goal was a higher powered self defense style load. At 6.4 grains I felt the load was nice strong and solid with out too much Recoil.

this was all out of a 5'' 1911

M&P. It's also my current carry gun. :P

I run hot 45 acp loads in my 460Rowland barrel.

The brass doesn't like it when it makes it's way into a regular 45 barrel.


If you think 40 looks like 45, wait until you have a handful of 45 and 460 at the same time.

Reading is fundamental but the little words are so tiny.

the obvious answer is to ditch the Tupperware and buy a 1911. I have run thousands upon thousands of rounds with 3.2 of BE behind a 185, works great
