[QUOTE="mikebob, post: 1273429, member: 6041"] the temp i have saved in the app is 32 deg that is what temp was day i sighted it in and done ladder test with chrony. i think the saved fps is 2403. when my phone is charged i will hit the edit button and see what zero velocity was at 32deg. varget .19 for 308win h4350 .29 for 308win retumbo .49 for 300wm rl17 1.4 for 308win vatget and h4350 input is from a few test firings so may be off a little just what i came up with trying these 2 powders out with this load so far. i have tried both of these and both shot very consistent at 825 with different bullets. never noticed it change then but again was not looking for it. retumbo i have never noticed it change but never really looked either. i have shot it for years and this lot .49 matches perfect. .31 lot before this one rl 17 just a few shots also but from the 32deg day to a 65 deg day i came up with 1.4. i have not shot this one other than working loads seating depth at 47gr from ladder test. this one might have to be my alternate until i can get my hands on h4350 again. i am out of my last 8lb and can only find a few 1lbs around with different lot# It may not amount to a hill of beans it just something i stumbled upon one day at the range. i have never had a problem with it in the field hunting or shooting targets always seems spot on. i could have made a mistake in one of the setups i was doing varget and h4350 on same day and got one mixed up.
