[QUOTE="FEENIX, post: 1000547, member: 14204"] I don't want to hijack this thread so I'll do a one time response to your query. 1. Check out page 6 of 12 SAAMI velocity and piezoelectric transducer pressure test >>> [URL]http://www.saami.org/specifications_and_information/specifications/Velocity_Pressure_CfR.pdf[/URL] . .270 Win's pressure limits is comparable to that of .280 AI. 2. In my area on the shelf availability of brass goes to the .270 Win, heck they seem to be the only brass that are constantly available around here. 3. It also depends on your set up. With today's advancement in barrels, powders, bullets, etc ... end-users are pushing the envelope. For instance, my .270 AI with 30" 1:8 twist 3-groove propels the 175 Matrix VLDs (165/175 BCs are in the .640/.650 range) in excess of 3000 FPS (2919 FPS while fire-forming). Just my 2-pence for your thoughts. Cheers! [/QUOTE]
