I'm shooting the 108gr ELDM from a 6mmGT in a Brux barrel. I tested loads with one particular box to check if my barrel liked the bullet - shot 3x 10rd groups around 0.5-.0.6 MOA group size (0.05 - .06MRAD mean radius). Seemed all good, so I purchased 1000 bullets of a different production lot, and now I'm getting 10rd group sizes around 0.9-1+ MOA (mean radius 0.07+ MRAD) with that lot.
This is pretty frustrating, all I can pin it on is lot-to-lot variation in the bullets - the 1K I bought coming from a lot where, for whatever reason, the quality of the bullets is lower.
Anyone else seen a degree of lot-to-lot variation like this?
If that's the problem, what can be done about it? Really hard to test a production lot before buying the same lot in bulk with the market conditions these days
