Factory Second Bullets 303 Caliber and 7.7mm Japanese

[bob q]

The military 7.7mm Arisaka bullet is right at .310 and the groove can be between .312 to .316 [ same for most .303's ] . The average WWII British .303 bullet is about .3095 . Both are bore riding bullets with a flat / exposed lead / hollow base to expand and seal the bore . With a small dia boat tail bullet accuracy is lacking , even at 100 yards . But in stock form with original sights it is very hard to shoot a t-99 Really well with about anything . In our 15+ years of every weekend military rifle matches we have great accuracy from most military rifle types , except the Enfield and T-99 . They just could not shoot on the level with the others and people quit shooting them , they could do about 3 to 4 inch 5-shot groups at 100 yards on demand , but in our matches that was not good enough for a win . . We had to hold matches just for them . But then again most people will not shoot at that level and will be happy with the results .
