I have made some 62 grain RF bullets and loaded them with 24.3 grains of N135 and traveling aroung 2,850 ftps. I use the Serria reloading manual as a refferance which has neaver let me down.
I shot this morning at 200 meters the above load tumbles and has a spread of about 4 foot, i am using a AR15 straight pull, with a 1:8 barrel.
I realise that I need to do some work to get the right load and i don't have any experiance of tumbling bullets - My quandary is do I need to go faster or slower.
Any help would be great,
Mozz
