I'm having a look at reloading for my club and had a look back at this post I posted a while ago: Long range .303

A question I do have that may be a silly one:

As far as I know companies such as Privi and S&B are only producing new .303 for those of us who shoot Lee Enfield, Ross rifles and a few Vickers etc here and there.

Is there a good reason why they don't make the rounds to the same specs as the old ammo?

From what I understand the .311 is only used for .303 so why don't they make a flat-based bullet instead of boat-tailed? In the same way I think I remember it being mentioned that the modern ammo is a bit hotter than the original stuff (correct me if I'm wrong, I think that's the reason given for the trajectory not conforming?) - so why don't they put a bit less powder in?

Had a search on the forum and a quick google, couldn't find any other posts asking this.

In regards to my reloading, definitely starting with .308 as it seems a bit easier
