I like to give everyone the benefit of the doubt but I may have to agree with Haider on this one. If Tex can rep out close grip BP's with 315 (as stated in his past post) than regular grip BP's should be at least 340+ for easy reps. Doing 275 military presses (seated) is not almost the same weight as doing his benches. If Tex did start the presses from 4" above the clavicles than that would mean he started from a weaker position than if he started from the cavicles themselves. Which would also mean Tex is one super strong presser for his bwt. I hope he his, but some of his post do sound a little extreme.
I'm no gage by any account but pressing from a power rack I use 325-340 for full reps, which is a little more than 100 lbs over my present bwt. I allow a slight knee action at the beginning of the press. Also include PBN's (BNP's to some of you) in a pressing program. I have not included regular BP's for quite a while in normal workouts. When I go back to benching, from time to time, I always see improvement in the lift. I would think that regular and PBN's improve the bench very well.
Military presses, as BrainX suggested, are not seated presses. The original military press was done standing with the heels together, knees locked (no action), back ramrod straght, neck/head held straight and not moving at all. Hence the name Military Press, done in a military manner. Good Luck.
