[QUOTE="Shawn Carlock, post: 105123, member: 4"] Just thought I would add some info for people getting ready to setup a 338 EDGE. About chamber free bore specs. Using the following components and load specs: 300 gr SMK H-1000 CCI 250 Rem cases 30" Hart barrel Loading the components with the bullet -.010" off the lands gives the following velocity and load. Assuming all other factors roughly the same. OAL 3.685" (HS box mag length) 91.0 gr 2814 fps OAL 3.775" (Wyatt's mag length)92.0 gr 2822 fps OAL 3.910" (single shot) 93.0 gr 2803 fps OAL 4.030" (single shot) 94.0 gr 2852 fps FREEBORE OAL 3.685" w/ .150" freebore 97.0 gr 2930 fps OAL 3.775" w/ .050" freebore 95.0 gr 2902 fps These are were all cut with the same reamer and throater. Just supporting info for the EDGE everyone elses info may vary. I have also noted that Fedral brass weighs slightly more than the average Rem brass and uses slightly less powder for the same preasure. The Fed brass holds about 1-1.5 grains H2O less than the Remington. Using H1000, the SMK, & CCI 250's I have gotton ES of 5-8 fps for 10 rounds. However you must measure the SMK base to ogive length and use only ones that are the same, doing this saved 8-10 fps in ES. Trim the tip, seperating by weight, find some good shooting conditions and 5-6" at 1000 yards is not a difficult deal. [/QUOTE]
