[QUOTE="Pdvdh, post: 279855, member: 4191"] 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 = [U]2980[/U] 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.
