Thread: AR2206H

Anyway put several of my loads of 45.3gr 150gr Sierra Pro Hunter past the Labradar chrono this morning and the velocity was only just hitting 2,500fps out of a 20" barrel. Something was wrong as I should be getting 2,800fps as I normally do with this powder.

Had a bottle of the same powder I bought at the Sika Show of a different batch number so loaded up 45.3gr of that, hit the range and the velocity averages 2,806fps for five shots (where it should be). Had this happen before with a lot AR2208 so not very happy about such a variation. I like AR powders but 300fps difference is ridiculous.

The batch number of the slow powder is MEM7041.

@10-Ring ran my load over the chronograph today, getting 2760fps with 16" barrel 308 (150gr BT). Wonder if your bottle got heated or something in transit? I was quite surprised by the velocity.

Thanks Hunty1. Yeah, may have been overheated, but not by me. Bought it direct from a shop in Auckland last time I was up there and kept cool on the journey home. Incidentally, how many grains for your load?
