For reloading you'll need either .311 or .312 diameter bullets. They are a little pricey, but the Sierra 174 grain Match Kings shot really well in mine when I still had it. Graf's & Sons ( Graf & Sons - The Reloading Authority - Your Source for Shooting Supplies ) often has PRVI Partizan new, unfired brass available and it turns out that Hornady made some .312 diameter 174 grain boat tail bullets very similar to the Sierra Match Kings that worked almost as well as the .311's. Hornady also makes a very good hunting bullet, their number 3120 which is a 150 grain, .312 diameter spire point flat base bullet that was quite accurate at 100 yards. The 174 grainers should work better for the 200 yard & beyond shooting though. Watch your cases when you start reloading - if you start getting a real bright, smooth band near the rim, they are getting stretched and you should watch very closely for cracks in this area. If you want your brass to last a lot longer for reloading, you should get a good neck size only resizing die and after the first firing, neck size only after that. Cases will then last for a few more reloadings than if you full length resized them every time.Thanks for the reply. I've shot it alot and can do decent groups at 100yds with open sights. I want to get tighter groups on the 200yd range. So far the headspacing seems good. I will be reloading soon since ammo costs so much if you don't want surplus stuff.
When you get up to speed on reloading for that .303, PM me and I'll pass along a few tips I learned when I had mine. I think I still have the notebook I kept when I was working on finding a really accurate recipe. I managed to get one going for the Number 4, MK1 that I used to have. It would do 1" groups at 100 yards if I managed to do my part. Very accurate rifles, those Enfields.I'm going to check the bore size and cast my own to match the bore. I'm going to reload for Star 9mm largo first than tackle the rifle cartridges this spring. Its great to have a friendthat wants to teach you how and has been reloading for many years.
I have only one caution regarding getting started in casting.Jim that would be awesome. My friends casting odd ball stuff is buried in his shed. Need to wait for the snow to melt so we can get it unloaded. Lol
