[QUOTE="Western4444, post: 2172735, member: 118447"] Thank you. I look forward to participating in the forum. Yes, this it makes sense to me that the 6.8 Western is a more efficient cartridge. But the 270 WSM cartridge can hold so much more powder that it makes up for its shortcomings. I have lots of additional powder capacity in my cartridges if needed, and easily and safely reached the the factory 6.8 Western velocities without issue. A big advantage in just rebarreling a 270 WSM with a high twist using SAAMI spec, the cost is minimal. Bought a Rem Varmint Barrel from Brux Barrels for $300, and $200 for gunsmith and muzzle brake. So for $500 I am shooting a 270 WSM wildcat [equivalent] version of "6.8 Western". And am achieving as good or better results than a 6.8 Western with factory ammo. As you correctly pointed out it may not be as efficient. But I achieved these 3000 fps velocities with less powder reference in the Hodgdon tables, significantly less. The question I am interested in knowing is how much more efficient is a 6.8 Western over a 270 WSM with high twist barrel using SAAMI Spec. Or is it really more efficient? I am not sure! I am easily pulling significant velocities using my Win 70 Short Action COL of 2.965". In my case I see no need to increase the freebore of my barrel and extend the action. I am getting absolutely great results. As this is primarily a hunting gun I will not be shooting more than 30 rounds a year with it, if it is not as efficient as 6.8 Western, I can live with that additional powder cost. Again thank you for welcoming me into the forum. [/QUOTE]
