Update on the 175 LRX load. I reduced the oal from 3.785 to 3.730 ( got the idea from Dubyam TKS ) and just like that sub moa groups, ( .612 at 100 yds). Vel remained an average of 3405 ft/sec. Should be a great load. Will see later what it will do at longer distances.

For those of you  that may be interested I worked up some loads for my 257, 270 amd 7mm Weatherby mags using Rl 26.In my 7mm I used the 175 gr Hornady Spt and worked up to a max in my rifle of 73grs of Rl 26 with a Weatherby case , CCI 250 and an oal of 3.370. Vel was an average of 3128 ft/sec in an 26" barreled Mark V
 In my 270 WM I used the 150 gr Hornady spt on top of 74 grs of Rl 26,  a Wea case Fed 215  with an oal of 3.350. My avg vel was 3194 ft/sec with a 24" barrel.
 In my 257 Vanguard I worked up to a max of 71grs of Rl 26 with a Sierra 117 Game king, Fed 215 Nosler case and an oal of 3.265. Vel was an average of 3375 ft/sec. with a 24" barrel.
 Overall I would say it is a great powder from the stand point of velocity. As far as accuracy I didn't post any results because what may shoot for me may not be worth much in your rifle, although accuracy was decent for me in such a small test.
 I worked up to these powder levels using the standard pressure signs as well as pressure ring measurements and my chrono.

Amazing velocity for the 117gr Sierra Game King.
Sorry... Yesterday was the last and final day for any and all complaints whatsoever.

I try to avoid temptation unless I can't resist it.

Everyone has a photographic memory.Some just don't have film.

I started at 65 grs and worked up from there. When my pressure ring measurements equaled that of my max Rl 22 loads I stopped. The look of my primers also told me I was close.

Thanks. Hopefully i can find some time to do some bench work and find a good replacement for rl25.
