[QUOTE="budlight, post: 2807957, member: 2939"] I see these points: [B][I]Gas system length isn't as important as gas port size, period! The 6.5 and 300 would require different gas port size at the same location. All though both have almost the same max pressure, both will have different gas volume amounts.[/I][/B] So just for the fun of it I looked up 6.5 PRC and 300wsm in Hodgdon reloading both using magpro powder and both chucking the spear (bullet) at @3000 fps. I used the same powder and same max loaded velocity out of each respective round. I had to juggle the bullet weights to 140 for the 6.5 and 180 for the 300 to use the same powder and attain the same velocity. I think that if you did scientific testing you would find the above statements to be incorrect. I reload 300WSM and 308. The ratio of case size volume to bore size generally requires faster powders compared to the 6.5 prc which is more overbore and generally can take advantage of slower powders. You have to compare apples and apples [/QUOTE]
