[QUOTE="VinceMule, post: 2979981, member: 122164"] Mike, I never said the Weatherby brass was soft, you miss read. When I had my custom reamer ground with the short neck, I made an adjustment on the freebore dimension. The Freebore dimension starts at the end of the neck. The carbon build up on the shorter neck with Chamber is no different than the Weatherby brass in a normal chamber. Two benefits: A. shorter freebore-benefits are many B. Brass availability-Winchester brass is plentiful, AGD maybe a game changer in terms of getting tough brass. Compare costs of 100 Weatherby cases vs 100 Winchester cases. The benefits of the Short Neck and the minimal freebore are based around a Custom designed chamber. Guys that shoot the short neck brass in their standard weatherby chamber will have to remove the carbon in the neck simply by using a bronze bristle brush, ten or so twists with bore solvent on the brush. Seat he bullets to the same COAL as you would if the neck was longer. The simple fact of .375 freebore in a standard Weatherby chamber does not leade to any apreciable barrel life, I have shot out a few Mark 5's. The shorter freebore lends to much longer barrel life in that factor alone, short neck or not. I shot the 115's around 3350 in my Mark 5's, Mike I would love to know your load you are getting with that speed, it is incredible to say the least! In the short freebore chamber in the 9T X caliber barrel, the 115g Berger is 3590 fps, groups are sub 3/8", same for the 110g Nosler accubond. R#22 with fed 215's is the powder used, with the 100g bullets at 3850 shooting groups in the high 2's, and the 85-87g bullets with R#19 at 4130 fps. I used the 257 Weatherby like most would use a 22/250, Ruck Chucks, jack rabbits, and calling in coyotes on longer shot stands in Nv. [/QUOTE]
