Good afternoon,

I'm trying to get an idea of how my loads using the maximum manual charge of Blue Dot in the 10mm Auto case (10.4 gr.) and the 180 gr. Hornady XTP bullet compare to others when fired in the pistol barrels.

If you would, could you post your velocity figures for your Blue Dot 180 gr. bullet loads? I would also like to know the barrel length and charge weight.

Thank you.

Hobie--

I can't help you with Max velocities. I can tell you that I have been loading 10mm for for 13 yrs. I use B.Dot and have loaded the 180 XTP. I use 10.0g and have achieved very good results out of my 1911A1 pistols. the barrel lengths are standard. The book lets you go higher than 10.o g but I found this to be accurate with a ragged hole in the target at 25 yds. You did not say whether you plan to shoot your XTP's out of a semi auto or a revolver. I am sure you can go higher with the powder charge in the revolver (especially the BH .38-40/10mm). Nice to see another 10mm fan on the forum . My best reslts are out of the SA Omega which I do not shoot that often

Apparently I wasn't clear. I just want to know the velocity you get with that load. Yours is a near perfect comparison for me.

FWIW, I'm not trying to max anything. I'm not trying to compare guns. I don't care about accuracy at all. I AM trying to compare performance of the same charge in different barrel lengths. For my purposes the type of gun is unimportant.

I can assume that you have a 5" barrel. Do you know what your velocity is?

Thank you.

Blue Dot is too bulky to get high velocities in 10mm.
I can't get more than 13.25 gr. of Blue Dot with a 200 gr bullet (moderator: This is a huge overcharge and should not be used, max listed by Alliant is 8.9gr) to fit in a 10mm cartridge in 1.3" OAL.
That load is wimpy: low pressure and low velocity.

If you want 10mm to rock, use 800X [I use 14.2 gr 200gr (moderator: This is a huge overcharge and should not be used) ], and if that powder won't meter, use Power Pistol. 3rd is LONGSHOT. Blue Dot is way down there in the 10mm power strugle.

Alliant shows 10.4 gr. with the 180 gr. jacketed for 35K CUP and approx 1200 fps, presumably from a 5" barrel. How is that way down on the list. IME, Blue Dot is the powder for the 10mm Auto.

HOWEVER, that is not the purpose of my question. I want to know what velocities other shooters are getting with Blue Dot in their barrels. I'm interested in seeing how much the bore expansion ratio of this particular cartridge with this particular powder affects velocity in different length barrels.

Well I had an interesting day today. I took out the Blue Dot load which I had yet to chronograph. I got 1271 fps with an AD of 23 fps and an SD of 32. It was pretty accurate even to 150 yards but much slower than expected.

Why? Because I can use the old BullX 180 TC over just 10 gr. of Blue Dot and get 1510 fps!

Since nobody wanted to answer my question (or couldn't), I thought I'd let you know what I'm doing. I'm trying to match/duplicate the .38-40 rifle in my 14" Contender barrel for the 10mm Auto. I see that with this cartridge the bore-expansion ratio must be such that lengthening the barrel doesn't do a whole lot for velocity. A 5" barrel we have access to does almost exactly the same velocity as my barrel with all loads!
