Hi, me & my mate use a 303 Lee loader and we share a 303 Enfield 1945 mk4

We share the cases & find that once we have fire formed our cases in the rifle then we only have to neck size them

The powder that we use is Hodgon Titegroup it's a hot pistol powder

At 25 yards indoors & 50 yards outdoors 4.5 grains titegroup is enough to get a good group as long as we boresnake the barrel after 20 shots

With the Lee loader you can light crimp the neck & bullet which cuts down on fouling in the barrel

We have the Lee loader in other calibres too but I guess if you were loading large quantities then dies & a press would be better

I use a hand primer for all cartridges, at £26 & £3 for a shell holder for each calibre it's worth it as I don't like using a hammer to put the primers in

Also, I'll prime all of the cases and then we share them out between us

Hope this helps

Regards Steve
