Re: 24 vs 26
More advantage to the 300 than to the 338. In either of these two cartridges it will make very little difference, I would be willing to bet 30fps at most in the 300 and even less in the 338. Both are adequate at 24" but then again I would use 26" myself because I don't really notice a difference between 24 and 26 when carrying. The old 50fps per inch is bull.
