+P and Max Loads

[Kango]

For HP-38 the max load in the Hodgon manual says 5.3grs but they have +P listed as 6grs. It also says in the +P section " No reduction in charges recommended with these loads. These are high velocity loads only"

So is it not safe to put more than the max in non +P brass?

I was thinking of testing 5grs of HP-38 anyways.

A prudent person would respect that information. Work up the load data using a chronograph to guide your load development. What caliber are you working with?

.45acp

HP38 and 231 are very similar, okay they are nearly the same powder! Just branded and packaged different. There are some better powders out there to push the limit of the 45ACP. http://www.realguns.com/loads/45auto.htm I would say look at ATK Power Pistol! http://recipes.alliantpowder.com/

Trying to use less powder per charge. I was going to use Bullseye but people say its really dirty.

Be very careful when thinking that W-231 and HP-38 are the "same" powder. I would not use W-231 values inplace of HP-38 or vice-versa as load manuals list different charge values for them. They may be close, but they are NOT the same...

For all intense purposes HP38 and W231 are the same powder, although packaged different but made by the same company. :banghead: But, the advice not use same data is valid! But they are the same powder!

Good Morning...

Calibre .45 ACP
Bullet 185 gr JHP

Hodgdon HP-38 5.9 grs (no W-231 listed)
Winchester W-231 6.2 to 6.8 grs (no HP-38 listed)
Lyman #48 W-231 4.4 to 6.1 grs
HP-38 3.5 to 5.8 grs

This is only one sample. I love a free country where we can all have our own opinions. You can also be the judge as to whether you want to load one or the other or both, but I value my fingers. Without them I can't count worth a darn.....

Warning: Some of these loads are maximum and should be worked up to
carefully.......

Let us compare apples to apples!

This is current information from the purveyors!

The look at the pressure #'s.

 

[The Bushmaster]

There is enough difference in the two according to the various manuals to be a bit suspisious. If you are not....Load up... There even differences in pressure between the various manuals...I have the conversion from CUP to PSI for rifle but not handgun. I'm a W-231 fan anyway...

Try titegroup,bullseye is #7 on the burn chart titegroup is #8.Titegroup burns clean bullseye doesn't.Hodgdon means what they say when they call it tite group.I get real good groups in my .357's the stuff isn't position sensitive like bullseye.But be forwarned both powders will burn the bases on cast bullets.

Nope, load as light as the data for the non +P brass.

That depends on the gun to a certain extent. Pistols with fully supported chambers can take +P loads in standard brass. But many 1911's have unsupported chambers and +p loads in non-+p brass can cause the thinner case head to bulge or even rupture. I have run hundreds of hot loads through my S&W 4506 using regular brass, but in my Colt MkIV or other 1911's I use +p brass for +p loads. I am by no means suggesting that you not follow the load data, just illustrating why it states the requirement for stronger brass with hot loads.
