7mm Ultra Loads?

Long time lurker, first time poster...

I've got a Remington 700 CDL in 7mm Ultra that I've just completed the pillar bedding on. I'm a bit partial to Sierra, and I talked to Sierra about the fact that there is NO data in their manual for this round. A nice "engineer" told me that the reason stems from brass that's too hard (from Remington) and they did not want to get into annealing in the manual. After reading and reading and reading some more (and using a ballistics program) I'm convinced of the superiority of a heavy for caliber bullet. I'm looking at 175gr only. Does anybody have any experience with this caliber? Loads?

The experience of this site is much appreciated.

The only bullet I have shot in mine so far is the 150 gr Ballistic Tip. 90 gr of IMR 7828SSC with a Fed 215GM primer will comfortably launch it at 3375 fps out of my factory 26" 700. Groups run around .5" or a little less at 100 yds. I know this is a little lighter bullet than what you are looking at. You might also look at the 160 gr Accubond in addition to the Sierra 175. Best of luck with your rifle.

Hicks,

Remington brass too hard? Nah, I don't think so!

Google around, you'll find something.

Try Accurate Arms, they have loads but for some reason, if I recall correctly, don't list 8700 for that cartridge. I'm a bit fuzzy on this one though.

Hicks take a look at hodgdon's web site and you will find data for the 175 grain. I have 3 set up using the 160 accubond with retumbo and played with the 175 Seirra and US869. They did shot out of a 9.5 twist ok but ended up being to long for the current mag. length so I went back to the 160 accubond. Recoil grows also with the 175 and a brake really is needed. Dave

Thanks for all the info guys! Budman, just currious, what velocities are you getting with the 160grs?

Ok, so I should not worry about the brass? Well, that makes my weekend a little less complicated...
