Yes I have put them back to their original specs and I send them to you when I'm finish everything up. :D

Added the following load data for the BB 340 load...comparison of Hodgdons data...
Hodgdon's 2012 Annual book shows 2 Loads using the 330 gr BTB LFN GC over 19.0grains of Lil'Gun @ 1332 fps from 8.275" barrel and the 355 grain BTB LFN GC over 17.5 grains of Lil'Gun @ 1247 fps from the 8.275" barrel.

Are 110 and 296 the same or you can't decipher?

sqlbullet

They are the same...Just different labels, at least right now.

But, and we say it all the time, always use current load data.  In 1970 H110, Win 296 and AA#9 were all the same powder.  Today that is not the case, with AA#9 having a faster burn rate.  It appears that what has actually happened is H110 and Win 296 got slower when AA#9 stayed the same, but who knows.

Gotcha. The .44's from them aren't very strong either.

The_Shadow

I was looking in my Hodgdon's book and they show more powder than what DT is using for the 240 grain JHP...this was a bit of a surprise for a company that is selling ammo on the premise of being higher performance stuff.

This is why I like doing the studies and I roll my own...compare notes, load and test to see how and what works, is accurate, clean burning performance from my guns.  Then if needed, I can make adjustments or refine things.

   What's the true performance standard for .44 Magnum in 180, 240 and 300gr? You know I have tested many and can only judge by my hand and F1 Chrony instruments  ;D

The 44 magnums as you have see with the Buffalo Bore 340 grain they load they specificaly said fire them ONLY in certain guns and NOT to be fired in others guns...yes some of the guns are built stronger and better materials.  But they don't list whether the loads are over pressure or not!

The hottest max loadings listed in the Hodgdon's 2012 annual shown as;
180 grain Hornady XTP with H-110 or 296, 31.5 grains @ 1896 fps 29,900 CUP(low pressure compared to other rounds with less velocity)
Lil'Gun 31.5 grains @ 1859 fps 32.300 CUP

240 grain Nosler JHP
H-110 24.0 grains @ 1522 fps 36,200 CUP
W-296 24.0 grains @ 1522 fps 36,200 CUP
Lil'Gun 24.5 grains @ 1582 fps 38,100 CUP

300 grain Hornady XTP
H-110 19.0 grains @ 1325 fps 38,800 CUP
W-296 19.0 grains @ 1325 fps 38,800 CUP
Lil'Gun 17.7 grains @ 1280 fps 37.600 CUP

The Lyman Devastator 260 grain Cast with gas check that I sent you were loaded with 16.2 grains Blue Dot @ 1455 fps should be about 37,000 CUP

So far the PBR .44 are smoking. I was possibly going to get a box of these just to see what they are made of but... crazy expensive and with the information I have now not much greater than Buffalo Bore:

The 330gr Hammerheads!

Intercooler

Buffalo Bore fell short only giving 1234 FPS. You think that 1400 FPS is realistic or they hanging out with someone else in Utah  :o

The_Shadow

Hodgdon show that 330 grain BTB LFN GC  loaded with 19.0 grains Lil'Gun @ 1332 38,000 CUP
Hodgdon show that 355 grain BTB LFN GC  loaded with 17.5 grains Lil'Gun @ 1247 37,900 CUP

Thanks for the info. I was about to add them into the sheet but didn't know the rating.
