I have a pet load for the 35 Rem using H4895 and 200gr Corelokts. Its 2180fps at 70 degrees F. And its 2160fps at 40 degrees F. And it could be any where between -10 and 40 dgrees in MI during deer season. I just have to adjust, but it works good and is accurate enough for 15-150 yards shoots. This is an extream powder as well not a powderknown for large tempature veriations. I use the same H4895 for the 358 Win and do not see anything that extream with temperature changes in the 358 win?
