[QUOTE="budlight, post: 990315, member: 2939"] I used 7828 ssc & AA magpro with magnum rifle primers with my 270 win 29 inch barrel shooting 169.5 VLD's I did not have H1000 or another possible choice would have been reloader 25 or even the new RL 33 I have heard that increasing twist drops velocity. But I think it also has to do with barrel type, number of grooves (Lands) I have an AR 20 inch stainless Match 1:9 and a 20 inch chrome lined 1:7 The same ammo chronos 40 fps slower in the 1:7 [/QUOTE]
