[QUOTE="AZShooter, post: 874414, member: 5219"] Mudrunner, just crunched the 308 with 210 VLD at 2400 comparable drift to the other cartridge /bullet combos I mentioned earlier is not even close with 12.7"drift Why not seat the 300 gr bullet in a 338 Win Mag to fit and feed from magazine? It might end up right around 2600-2650 fps. If I can seat a 230 hybrid into a 300 WSM to fit my friend's ridiculous OAL of 2.8" and get 2720 fps then the concept could work. I know the STW AND the 7 LRM will get the 180 to the velocities where it easily competes with the 300 gr hybrid from the 338 RCM. A 32" barrel with a 7 rem mag will do it too. Scottyd, I will admit that 338 RCM brass is hard to find. Easily found the hornady die set with first try: [url=http://www.opticsplanet.com/hornady-new-dimension-series-i-two-die-rifle-set-338-rcm-546399.html]Hornady New Dimension Series I Two-Die Rifle Set .338 RCM 546399 FREE S&H 546399. Hornady Reloading Dies and Die Accessories.[/url] If you decide to go with the 284 I'd suggest you use 6.5-284 Lapua necked up. As for accuracy, I think you will be fine. My opinion is that you should seek out a reamer design with a throat angle of 1 degree 30 min. Lapua is pretty consistent so you probably don't have to go the neck turning route. Good read on how the BR/F class guys are setting up their 284s: [url=http://www.accurateshooter.com/cartridge-guides/7mm/#284win]7mm Cartridge Guide within AccurateShooter.com[/url] [/QUOTE]
