7mm-08 with 162's/168's

[Ackley Improved]

I have been searching this site, and many others chasing info about the 7mm-08 in regards to the heavier projectiles. I have found some data, but I would like to hear from guys shooting it just to confirm, before I commit to a barrel.

So either in the standard, or Ackley form, what velocity (without running hard) are you getting with the 162/168's.

Also barrel length!

Thanks

The consensus seems to be 2700-2750 from a 26" barrel, and that AI doesn't feed well enough to justify the marginal performance gains.

Try the search link in my sig, might make locating the threads your looking for a little easier.

See Sig for barrel specs:

162 Hornady BTHP
Win Brass
47.2g H4350 (compressed load)
CCI 200 primer
2.870 OAL
2780fps

Absolutely no pressure signs and it's also very temperature stable.

Good luck,

That seems awfully optimistic, are you getting that from a chronograph (what brand) or by reverse engineering your observed drops?

I agree, but the chrono is confirmed with other rifles of known speeds, also that is suppressed. I tried quite a few powders before I found H4350.

You say "rechambered"... it wasn't originally a 243, was it?

Ha, no, barrel just set back when the action was trued, it was always a 7-08.
