7mm08 quickload request

[308 5R]

Good Evening all,

I'm about to possibly have two matching NULA rifles built and I was wondering if someone could run QL on this cartridge for me. With the NULA's running a 3" box I'm curious about running a 2.950" COAL and gaining a bit of powder space. It's free I figure I might as well take advantage.

7mm-08
60k psi
140 NAB 1.290"
160 NAB 1.410"
2.950" oal
22" bbl
Win brass unfired 55.4 gr

Thanks in advance

No? Am I missing some info? Goal is to hit 2900-2950 w/o psi that is overly hard on components. I would assume all things being equal that this would effect normal book loads considerably given the .150" delta on OAL.

Which powder(s)?

Just looking for something that may get me to that velocity target or as close to it as possible.

I have on hand:
IMR-4064
Varget
Imr-4350
H4350

I have been reading that RL61,17, and 19 as well as Big Game maybe some other good options. Mainly just a feeler to see if I can get to 2900(+) by extending that OAL out of a 22" barrel. Primary will be 140 AB.

With your information this is my findings, the report is only on the powders that gave the speed you requested at the pressure you wanted. The 160 NAB is a no go.

140NAB
RL16
47.9 grains
59,980 psi
2944 fps
7.6% compressed

140 NAB
RL17
49.2 grains
60,034 psi
2966 fps
2.6% compressed

140NAB
Ramshot Big Game
47.1 grains
60,003 psi
2885fps 97.5% fill this was close to your requirement for speed so I posted it.

If this is a hunting rifle and not a target rifle then try 2000MR. I run it in mine with WW brass and 140 NABs and 140SGKs over 46.8gr of 2000MR and run 2900FPS from a 25" tube with no issues. My rifle is set up very similar with a similar OAL to your using AICS mags with no plate.

Thanks for the information gentlemen. I just needed to confirm (understanding QL is not SAAMI) that it was possible to get what I was looking for. I appreciate your time.
