My 24" .280 AI shoots the 140 TTSX at 3205fps from 63gr of R22. Groups are well under MOA a d brass is on its 5th firing with no trimming and tight primer pockets.
That is 300fps more than any on my 7x57's would do and they performed great in the field. A little flatter trajectory and another 569FPE, that, is significant. John
When truth is ignored, it does not change an untruth from remaining a lie.
