I know you're right, I just want to burn the barn down for once in my life.
then when I re-barrel I will make it into a medium weight 22-250 AI with a fast twist barrel for the 90gn VLD as that's an itch I have been wanting to scratch for some time..

Not true. In the latest update they have all the Hammer profiles in there. So far it has been accurate within 2-3% of calculated velocity.
Well that's awesome, they have been off the mark until now, Thank you
Agreed. It makes it much easier to pick a powder.

That was a stage that lasted about 20 years for me till I figured out how expensive it was getting.I know you're right, I just want to burn the barn down for once in my life.
I still have a little of that in me though or I would not be shooting the 6.5 LRM and wanting to do slightly improved version next time around, the 7mm STW or the 300 Rum.
Truth is, I could kill the same game shooting a .260, 30-06 or 300wm, 7mm-08 7RM just as dead and have. In fact I took a break from the magnums a couple of years ago and shot nothing but the .260's. Same results, lots of dead pigs and dead deer.
But where's the fun in that when you can go 400fps faster or more!

I've found Barnes data pretty good with Peregrines is it reliable enough for starter loads with the Hammers?

That's kinda my question, where to start... when you have obscure caliber and obscure powder there will be a SWAG involved at least somewhere!
They have the profiles but they have been really off base so far with powder volume vs speed, the reduction in friction with the PDR grooves seems to be what is hard to account for

Course this project will be less of a magnum and more of a tiny tiny laser beam. The 6mm 115 kills with just a little too much boring regularity.

I might have to take one with the 338 just to compare and contrast the damage and time to expiration. Might have to write it up with pictures? whadya think?

Well generally drive band bullets run faster and at lower pressures than traditional bullets.
Maybe it's a difference in their groove technology? With the Peregrines I always felt pretty safe starting out with the closest bullets produced in the TSX/TTSX lines.
That holds true for hammers as well but I'll give you an example, My 270 AI with the 117 Hammer with H4350 is listed in the Hodgdon reloading manual, it's the max load (63g) listed for the 90g Sierra HP @ 3603 and I'm running the 117's@ 3532
