[QUOTE="benchracer, post: 1253424, member: 22069"] BTW, I have wanted to pick your brain regarding your expectations for the 338 Sherman, but hesitated to hijack someone else's thread to do it. When I first began to consider the 338-06, I spent considerable time thinking about the 338 WM relative to the other 338's. It seems to me that the WM occupies a sort of no-mans-land in terms of case capacity relative to available powders. Its case capacity is about ideal for RL-19 or H4831. Not enough capacity to make use of powders like Retumbo or H1000, like the RUM and Lapua can. Too much capacity to benefit from powders like RL-17. I have long heard the 338-06 described as being very close in performance to the 338 WM. From what I can tell, the right bullets and powders should virtually erase the performance gap between the two, especially in the AI version. Based on my research, from a 26" barrel, I expect to be able to push a CE 200 MTH to 3050ish (using RL-17), with accuracy, and be able to feed it from the mag. On the high end, it looks like I may be able to push the 285 AMAX nearly as fast as the various 250's (around 2600 with RL-22/Norma MRP), though I would have to single feed it. What bullets and powders do you have in mind for your 338 Sherman and what sort of performance are you anticipating? What barrel length and COAL do you have in mind? [/QUOTE]
