Bindii, if you are trying to calibrate for a 303, have fun, but this will help you with your 308 adjustments, it certainly works for me and most of the F class boys.

Glenn, I don't think we used anything other then MF rounds, the quality control and components were very good, even after 56 years a test of velocitys gave me these readings from MF56 ammo:
1. 2384 LO 2379
2. 2379 HI 2384
3. 2382 AV 2382
4. 2382 ES 5.62
5. 2383 SD 1.73 Now I have to say, if we could reload to that consistancy, we'd be laughing.
Just to back it up, different rifle, target barrel:
1. 2496 LO 2496
2. 2512 HI 2512
3. 2507 AV 2502
4. 2499 ES 16.59
5. 2496 SD O7.14
