[QUOTE="dbhostler, post: 29870, member: 799"] Len, Haven't worked with the heavy 7s too much. I picked up the Ultra later this year and began with a 140gr NBTs. Got those to shoot and then sent the rifle to Chris and had an OPS INC brake installed. The only thing I have at this time is 162gr A-Max with 96.0gr Retumbo lit by RP 91/2Ms for 3280fps. This is from a 26" factory bbl. As far as published data, most Ultra data is on the 30 and 338. Very little on the 7. If you can get "Speedbump" to chime in, he has shot the 7 Ultra in a match rifle for some time and has tried about every custom bullet and powder combo you can imagine. He is the one "in the know" on this subject. As a matter of fact, he necked down a 300 Ultra case and made a 7 Ultra before there was a 7 Ultra. db [/QUOTE]
