Load data for 6.5 Ultra Mag?

[jtoews80]

Would somebody run quickload and tell me where to start with this round, please. I'll be using 140 SMK's and 130 Accubonds, will try 142 SMK's if the 140's stabilize with a 12 twist. Powder is H870, 8700 and will get some Us 869 if I have too.

Case size????

What case are you using????

 

[jtoews80]

7mm RUM necked down to 6.5mm, no other modifications. It is the same as the 7mm, 300 and 375 RUM, not the shortened shoulder 338 RUM case.

I think I'll just start with a stout 6.5-300 wby load for a starter and work up. the wby case is 13% less volume.

6.5mm rum

Assuming that the only change is to neck down, then this should be close to what you are looking for. Used 142gn SMK, and standard COL.

This is a hot load near max, please exercise the usual caution and work up slowly

just wondering what length of barrel your useing?and velocity your expecting??

 

[jtoews80]

30" barrel with a rather slow 12 twist. I'm hoping to be over 34-3500FPS, but between 3300 and 3400 may be more realistic

I found this:

The 6.5 Allen Mag has essentially the same case capacity as a 6.5 Ultra Mag. Quickload has its uses, but the MV's shown in the PDF are exceptionally low - lower even than is found in the much smaller 264 Win Mag.
