Home Forums Reloading Big Game Rifles 7mm-08 RL17 162AMAX, 139SST

50grs of RL-17 did a cool 3000fps with the 140 Accubond from my 22" 7mm-08 AI today.......Start low and work up, yada, yada, yada...!

Now you guys got me wanting to build another 7mm-08 ackley since the fianc� took my other one over and I doubt I can take it from her grasp

Loading as much RL-17 as I was comfortable compressing in my 7-08, I could only get to 2800 fps with the 140 grain AB. Going back to RL-15 and/or Varget.

140 AB, 47.5 gr Big Game, 2843, WLRM, and bughole groups Tikka T3 Lite SS.

Never have tried Re-17 in my 7-08 M70 Fwt. When I first got it, I landed on H414 as what seemed to be in the sweet spot for powders and that caliber....using a Hornady 139 SST. It flat wouldn't shoot.

Ended up going to a Sierra Pro Hunter 140 over Varget. 2783 MV. It kills deer dead and shoots tight groups.

what gun / barrel was that and how much 17 were you using ?

Locate some IMR 4007 Stuff is excellent in the 7mm-08 with both 120 and 140 gr bullets feed with cci br2 primers 1/2 " groups in many 08's with both weights Barnes and Nosler mostly..

Too bad 4007 is discontinued.

Big Game.

Anybody running H4350 with 162's or 168's in 7-08?

I think JeffO was. Might do a search. Seems like he got about 2,700fps after some tinkering.

Not 162's, but I was somewhat suprised the other day when I finally chronographed my 145gr H4350 load from my 20" carbine and it broke 2,700fps. I think I'm one grain below Hogdon's max in my old manual. H4350 is a useful powder.

Hornaday list 2700fps with RL-17 and H-414 with 162's. one 7-08 I have 24" barrel runs quite a bit faster than their data with 17 43gr gives me 2646fps Hornady list 42.9 as 2500fps and 46gr 2700fps

A 162/168 in a 7-08 case? Hmm. I imagine it drops a ways below the neck.

It was throated for these and built on a long action. All the bearing surface is above the neck shoulder junction.

Fwiw, Alliant claims 48.7 gr as max for RL 17 and 140 Partitions in the 7mm-08.
