Re: H4350 Burn Rate Change?

My recent lots of H4350 are definitely slower with my max load increasing and a 80fps increase as well......I shoot a couple thousand 6.5 creedmoor rounds per year and have noticed quite a bit of lot to lot variation with H4350 as I've been mostly shooting 1# bottles cause that was all I could get, I've now gotten a couple 8# jugs of the same Lot number and in re-working my load I've increased 1.5 gr ove my previous max load and no pressure yet plus 80fps more, my SD kept dropping tho hotter i loaded it....I stopped when my velocity averaged 2830 with SD of 4.

I would say your experiences are definitely within the range of normal expectations.....

Re: H4350 Burn Rate Change?

My 8 pound jug of H4350 needs the charge entered in Quickload to be reduced by 4% to match the chronograph.

That is, the jug is 4% slow.
Or the QL library is 4% fast.

But Varget and H4895 are perfect a perfect match between the chrono and QL.
