[QUOTE="Long Time Long Ranger, post: 518539, member: 505"] Devin based it off a shortenned RUM case however I am using 330 Dakota brass made by Norma. It is good brass. The only thing is I have a slightly short neck that resembles the gibbs cartridges. That has not affected performance or accuracy in mine. I listed the case capacities of all of them over on the other thread if you want to look it up. I think the 340 wby is 6 grains more than the dakota and the sin is 6 grains more than the 340 wby. Not exactly sure but I think that is right. Then the 338 RUM is 6 grains more than the sin. 120 fps difference between the 340 wby and the 338-300 RUM so on average probably 60 fps between the sin and the RUM's. All of them are right in there. I can tell you from shooting a 340 wby for 35 years I can not tell the difference hitting an animal with it or the RUM's. Just no difference in a hunting situation. Taken elk over 1000 yards with both. 120 fps is just not enough to make a determination over other than clicks. [/QUOTE]
