[QUOTE="264MHC, post: 2061512, member: 111161"] So I’ve been running some numbers in Quickload with the following parameters: 65000 psi max .33 Weighting Factor (recommended for overbore cartridges, not sure how it translates to reality) 180 Berger Hybrids with bearing surface Seated .200 into the neck (assuming optimum free bore for various cartridges) This might turn into a book but here are the takeaways: 28” barrel minimum regardless of Cartridge, 26” just won’t do it. 110 Grain water capacity minimum Ramshot LRT, VV N570, R33, or R50 are the only powders that will do it. Adding 2” of barrel adds 80fps on up to a 40”, adding 10 grains of water capacity in the same barrel length only nets 30ish. The cartridges I looked at: 7-300 Norma Mag 104 Water-3330 7-300 Norma Improved 110 Water 3390 7 Rum 112 Water-3400 7.21 Lazeronni Firebird 121 Water- 3430 7-378 Weatherby 124 Water - 3435 7-33XC 134 water - 3460 I still choose the 7-300 Norma improved as it’s the only one on the list that makes the mark and will Mag feed without a special box. I would also still choose the 190s (3320) as they have less drop and drift and a lot more velocity and energy at 1k than 180s at 3400. [/QUOTE]
