Re: 168gr .308 to 1000 & Beyond .... Anyone Doing It???

The Hybrids have a shorter bearing surface. I found this to be true when I tested some .338 250gr. Hybrid OTM Tacticals for Berger in March. I was able to push them as fast as the Barnes 225 TTSX's in my 338 Ultra mag. But being limited to 100 bullets for the test, I could only do so much testing.
When I did the load development for the 168 Hybrids in my 308, I went up in 1/2 grain increments to find what shot the smallest groups. 47.5 grains AA 2520 grouped best in my rifle. I have loaded that brass over 5 times and don't have loose primer pockets and the bolt is easy to open. All rifles are different. Loading manuals are 10% under for safety and liability reasons.
Did you test for your max load and back down for load development?
At 48.5 grains of AA 2520 my bolt started to get hard to lift.

If anyone gets sub .5 MOA accuracy at 600 with AA2520 (that is, no group over 3 inches), they're probably the only one who does. Ball powder's never been popular with top competitors. 168's in a .308 case have typically performed best accuracy wise with IMR4064 or Varget.

I think you'll be hard pressed to get enough muzzle velocity with safe peak pressures from a 20 inch barrel to keep any 168 supersonic through 1000 yards. Same for heavier bullets in my opinion.

Re: 168gr .308 to 1000 & Beyond .... Anyone Doing It???

Sorry to hijack but im getting ready to start working on a load for my 308 win in a Remington model 700 sps varmint with a 1:12 twist 26" barrel.

I was thinking about the 185 gr bergers? Good choice? Or should i be using 175 gr bergers?
Ill be using it for 1000 - 1200 yard shooting using Varget for powder.

Thanks for any help, 500

If you're going that far (1,200) I'd recommend the Hornady 208 grain Amax.

What would the 185gr. Be good out to?

I suppose a 1000yds would be about all id be shooting with this stick.

With all due respect...you need more gun than that for 1,000 yard deer.

The 185 Berger has the power for deer to 600 yards...it lacks the BC of the 208 Amax, which has the power for deer to 800 yards and will be much easier to shoot in the wind.

For a 1,000 yard .30 caliber deer getter....300 Win Mag is the minimum, and a bit more is better.

Ya i was thinking about it after id posted and a 1000 for a non magnum is a little pushing it.

I have a 300Rum for the long shooting then the lapua for really reaching out there but i think all just keep the 308 for inside 600 as you had said.

For 600 yards being my max on deer would the 185gr be fine?
