[QUOTE="Broz, post: 604757, member: 7503"] Bravo, you are correct Hart makes a swedging tool and I should get one. But I kind of lost the need with Lapua brass. Both my son and I use Lapua brass in our 300 wins too. I have not used N570 and I am not familar with it. But if it will get me close to 3000 fps from my 338 LM using a 300 gr bullet I will look into it. RL 25 I have, but choose not to use it for a rifle I shoot to such extreme distances in a wide variety of ambient temperatures. I have owned many chrono's. and still own 3. The last one I bought was an Oehler 35. I have owned plenty that have really lied to me. The Oehler with a proof channel seems to be pretty good about telling the truth and spotting errorus readings. What velocity do you see with your 90 gr load of H-1000 and a 300 SMK? I have ran that load before several times and have accurate data. I not only look at a chrono for velocity but rather look at what actual drops dictate to well past 1000 yards when a proven BC is used. When you get the drops to match everywhere you are probably close with your true velocity. Jeff [/QUOTE]
