Thread: AR2209 Lot Variations in the 6.5 x 55.

I use 2208, purchasing large (10 or 20 kg) lots so I don't change batches often.
(We use between 10 & 15 kg a year)

The last time I had a batch change in 2208 I loaded 24 rounds with the old batch, 24 rounds with the new batch - everything else the same.

Off the the range.
Test fired 12 of old, let rifle cool then 12 of new.
No noticeable difference in velocity or group.
Shifted to a longer range repeated firing new then old.
No noticeable difference in velocity or group.

Conclusion same load will do, the nut behind the bolt is the biggest source of inaccuracy.
