[QUOTE="180pilot, post: 627013, member: 3897"] I have purchased a Savage Axis 7mm-08, which with just a magazine and composite trigger guard change, becomes a long action. Because I need to use 150 gr. Barnes TSX bullets and their long length, I've also purchased a PTC 7mm UNI Throater. My question is, has anyone else experimented with throating barrel lead and seating out long bullets, so start of boat tail is even with start of cartridge shoulder? How much more of a powder like 4350 or Reloader 17 can be used, then shown in reloading manuals? What velocity increase? Pressure problems? Accuracy??? This rifle only has a 22" tube, so will that restrict any increase? BTW the parts to convert Axis to long, cost me under $ 50.00 from Savage. I checked the factory throat with Hornady OAL, and when bullet touches lands, it is right at the COAL 2.80" of my reloading manuals. That puts about a 1/4" of bullet into body of case. ( includes boat tail). With bullet seated out with only boat tail below neck/shoulder junction, it measures 3.00" I need to still measure more accurately from ogives, but appears I would need to ream about 0.200" + whatever jump I want.
