Re: H4831SC acting flakey...
I have two lots that are running slow. Both lots still shoot well, but I needed 29.75MOA to get my 6.5x284 to 1K Sunday. The Sunday before last this load went to 1K in 26.5MOA. Last summer with different lots of H4831SC went to 1K in 24.0MOA.
Now, I can see the air temp/density accounting for maybe 2MOA from 70*F to 35*F, but there's no way this load is ruuning 5.75moa slower than it did last year without some serious change in retardant. Even with a 70* temp swing,, over 5 MOA is too much.
I'm starting to wonder just how temp sensitive H4831SC is. I have a feeling when it gets back up into the mid 80's,, it'll start working again. I got spoiled with VarGet.
