IMR 4166 vs Varget for 308 LC brass , I have tried 4166 found 1 load I like but 4166 seems to have a narrow window .5gr one way or the other made a big difference on grouping, I have read the 4166 pressure spikes quickly towards or near max loads, I stayed in the middle but wondering if I should start over with Varget ?
just curious if anyone has used both to compare ?
Im loading 168 amax LC brass ,
I know Varget is very popular and a cost less then 4166
