[QUOTE="jmden, post: 382348, member: 1742"] TH, What's the rest of your load for the 338 Lap Imp? Kirby is typically right around 100g Retumbo with the 300 SMK hovering just under and sometimes a fair amount over 3k fps MV in his 338 Lap Imp (Allen Xpress (AX)). That 300 SMK is better in virtually all departments that the 240, although I've taken a couple of elk and a deer with the 240 out of a RUM at 3K fps MV and about 104g US869. Ended up not liking dealing with the temp sensitivity of the US 869, so went back to Retumbo and 210 Bergers, but it sure packed a punch behind that 240, at least the lot I had did. I get the impression newer lots are faster burning--I couldn't get better than about 2920fps MV with the 240's and a new lot of US 869 before I started seeing pressure signs I didn't like.
