I had a Kimber Montanta in 7-08 cut it down to 13", I like to run heavy pills ( instead of light ones in short barrels, as people try to keep speed ) I go heavy for retained energy & to get the most out'a 08 based cases.
You want a fast burning powder in short suppressed barrels so my load was 160 game kings - 39g of 2206h doing around 2350 & shot .75 moa, so plenty good enough for a bush gun.

Running 42gr CFE223 behind 162gr ELD-M in my Kimber 7mm-08 with 16" barrel.
How you going for speed with that combo?Quote:

Nor is it necessary or probably safe in other rifles. Might even need reducing further. 162gr ELD-M ogive in Kimber is way off the lands also. Cheers
Thanks for that Joel
Looking at 7mm08 pistol data with 15inch barrel the faster powders (CFE223, 2206 and 2208) look more efficient with more velocity. With the 140s and above and longer barrels the data reverses
I think I’ll buy some CFE223 after I use up my factory ammo and see how it shoots with the 120BTs. Thanks for all the reply’s and data.
Give Win760 a go, can be a little temp sensitive but it works - I'm running 49gr in a 17" barrel, nosler 140BT @ 2760FPS. This is hot so work up to it.
Thanks - that is a hot load but good velocity

I have gained 100grms with scope but with the 1-4 x 24 - the 1x with middle size Red Dot on - both eyes open - just perfect in bush
So your Leupold 1.25-4 VX-R is now on Brno .22
Back with loads tomorrow when can find box in shed that nice chap on here did for me

@winaa and @Rated M for Magnum I chrono'd my 42gr CFE223 charge behind the 162gr ELD-M with my Labradar yesterday, it averaged 2488fps in roughly 12°C temp.
@joelhenton Thanks for that. That's a pretty good speed for a heavy (for 7mm08) bullet out of a 16" barrel.
Yeah I may need to reduce further, will assess when I get a chance. Would like to try measuring the web of the case for excessive pressure but would need to invest in a high end micrometer for that type of measurement.Quote:
