338 Edge - 265 HATs Muzzle Velocity

For the 338 Edge owners who might have the interest:

I worked up a maximum load in my 338 Edge with the 265 gr GenII HATs today. My rifle has a Hart 26" 10-twist barrel. MVs recorded over two chronographs, an Oehler 33 and a PACT PC2.

MV = 2980 fps
95.5 gr H1000
CCI 250M
RWS 404 Jeffery Brass

For comparitive purposes, my maximum load with the 300 gr SMKs was 2840 fps, so I'm shooting the HATs about 140 fps faster than the 300 SMKs. There was no appreciable velocity gain past about 95 grains of H1000 in this 26" barrel. With a 28 or 30" barrel I may have gained additional velocity with additional powder.

Pressure wise I believe I was getting toward maximum at about 96.5 gr H1000 in the RWS brass. The RWS brass is tough stuff so approach 95-96 grains of H1000 with caution if using Remington brass.

Hows the accuracy level?

Any bullet drop tests yet to see what the drop is over long range, probably not, just hope you report when you get it, very interesting.

140 fps boost is certainly useful if BC is same or higher!!!!

Keep us posted.

No drops, associated BC, or accuracy data yet. That's my next step. I'll post again when I have some data.

So the 1-10" twist stabilized them with no problems? I have been interested in trying some of them but wasn't sure how they would shoot in the 1 in 10" barrel that is on mine. May have to get some and try them.

Until he shoots them on paper, we won't know for sure if the 1 in 10" stabilize them.
