[QUOTE="MagnumManiac, post: 2401296, member: 10755"] A compressed load is dependant on two things, the amount powder used AND the length of the bullet. Often, a mildly compressed load gives much better ES/SD numbers due to what’s called consistent packing scheme. A heavily compressed load poses no danger to the burn, however it can cause issues due to pushing the bullet back out of the case overnight. I have had this issue with the 300WN in a 3.4@ mag box before, so changed powders. On the other hand, a heavily compressed ball powder almost always gives low ES/SD numbers due to the same packing scheme scenario. Compressed loads shouldn’t be avoided, but due diligence is needed to make sure no bullet movement is occurring. I love compressed loads in several cartridges because of the fact that low ES results. My 375 Weatherby with 760 compressed gives me an ES of 10fps, I use this on deer at ranges that boggle the mind with a 260g Accubond @ 3000fps. Cheers. [/QUOTE]
