180gr barrys TMJ .401 bullets and TiteGroup

[Shaunny Rotten]

I have very little experience loading the 10 so I may have some questions that seem silly but I really don't want to blow up my gun, again.

As stated above I'm loading 180gr barrys TMJ .401 bullets and TiteGroup.  currently I'm loading between 5.8 and 6.0 gr but they don't feel as powerful as I've been lead to believe the 10 can be.  6.0 is the max load that I saw on the loading data I was working with but that still seems light.  I know any weights past 6.0 are beyond the "safe" spec, however have any of you had success loading this combo beyond that?

Also, I am using a 10mm Colt Government, not a delta elite, a 38super frame with an aftermarket unmarked slide, with a clark barrel.

Shaun, I moved this topic here in the 10mm reloading section.  Tite Group is a faster burning powder therefore pressure starts to spike faster as you reach the upper limits, so it is wise to stay close to the book loads with this one.

Hodgdon shows the 180 gr JHP using 6.0 grains of Tite Group developing 34,300 psi and you may find a little more room based on your bullet being an TMJ and those pressures, but being a faster burn powder, you'll have to watch out for a pressure spike even with small increases in powder charges.  If you don't have a Chronograph you will be working blindly.

That's a good thing... not a second time.

Haven't worked with Titegroup, but see that even by the MAX  book load that your below the known max pressure for the 10mm...
Don't recommend going over book, but it does appear there is some play still. 
IMHO tho if your looking for hotter rounds, go with a diff powder.

As the shadow said be careful with titegroup, titegroup good for plinking loads but would not try to get to full power 10 mm loads.  ESPECIALLY WITHOUT A CHRONY

[Shaunny Rotten]

Thanks for the input guys.  I'll keep to the high 5s for now until I can get my hands on some slower powder, which is rather hard to do in my area lately. 

[Osageid]

Keep eye out for AA9,  H110/w296, 800x etc

[tommac919]

BlueDot works well too...

FYI; 800x tho good , meters so bad it's almost a weigh every round to get accurate amount

Agreed on the 800 x

[Shaunny Rotten]

I've heard that 800x meters poorly.  I use a Horniday Powder Measure, will it measure accurately or will I need to get the Powder measure close and trickle the rest of the charge into the case?

[The_Shadow]

I use the RCBS uniflow and drop even or slightly short and trick up, but I hand weigh all of the charges anyway...
It can be up and down with the way the flakes fill the meter tube.

I have used titegroup for 10mm but only in the book ranges. From memory 6.0 grain max. (Shadows advice is dead on, so I won't repeat that)
Have used TG with plated pullets at target ranges with good success (accuracy & economy) Not a good powder for pushing up to max velocities.

I would point out that TG is very bad for lead bullets because it smokes the lube (burns hotter than most powders). Haven't tried bayou bullets yet with TG (coating, not lube per se)

The problem with Berrys Bullets is they should only be loaded up to 1200 fps velocity max. Any more and it will start shedding that copper plating, and your pistol becomes a shrapnel firing machine. (Really bad if you're shooting a revolver!). It's fine for cheap plinking ammo but I use a real metal jacketed bullet if I want some serious velocity.

[sybo]

Gandog56 sums it up pretty well, plated bullets don't like speeds upward of approx 1200 fps. Accuracy suffers, you will get shotgun patterns, no consistency because the plating cannot withstand velocities above 1200 fps. Go with jacketed bullets for nukes!!
