[QUOTE="kraky2, post: 96932, member: 3532"] gnslgr-The 270 wby is a gun that's sometimes hard to talk about because of variables. I use Rem 7mmwby brass to make my 270wby brass. It has alot less capacity than reg wby brass and can make a 2-3 grain difference right off the bat. Also there are weatherby rifles and then there are others without freebore. So no matter what anyone says be carefull and take "loads" with a grain of salt. Also bullets like the 150 hornady for some reason may make less pressure than say partitions. All that being said...we got up to a very max load of 72.0 under 150 hornady using weatherby brass. His gun shoots this really good. When we played with the re25 we got up to 73.5 and that was absolute max. I have an older hornady book and it shows under their 150 grain bullet...72.2 re 22 and 73.3 I7828 as max loads. I think in the later books they dropped these down about 3 grains. I can't imagine you would be able to run any hotter than these published loads. We all know that WBY factory is pretty much loaded to the max. What I would recomend as a "thermometer" IN YOUR GUN is to chrono some factory ammo and be happy when you get to within 50fps of that with your loads. ABSOLUTELY stop when you match them even if you aren't getting extractor marks or bolt lift resistance. For me great accuracy near top speed is the goal but if I have to give one or the other up I'll sure take accuracy at 100-150 fps slower any day of the week. IE 3" groups at 300yds are far better than 6" groups or those with flyers. I hope some of this helped.....it's more theory than recomendation I guess. RE the OAL--I usually hang 'em out but I've seen where factory OAL has been the "sweetspot" for people too. It's all a matter of experimenting with your gun. [/QUOTE]
