Have you tried cast? I have done much better than that with several mid cal military rifles. 03A3. 303 Br, FR7. 8x57, 1936 MAS, 7.7 Jap, couple moisants etc. You need a good bore and possibly some load development. Been shooting cast for over 35 years.
Gosh there are a lot of people who don't realize this is under reloading lol. Done it myself I guess.
150 Berry Bullets for 3030.
Shot under a 3/4" group at 100m with them. And cost me less than 30 cents to load.
