[QUOTE="Muddyboots, post: 2034860, member: 63925"] Offer the following info on 300WSM with the 162 AH. I used what powders I had on hand and never really did get the velocity bump that is prevalent with the AH but probably didn't find the right pixie dust. Remington 700 - MagPul Stock 26" Preferred Barrel - 5R - short throated to bottom end of SAAMI for my short 2.900 COAL limitations (🤬) to help minimize jump. 2.900 COAL - 0.085 jump (added this in as edit) Hornady brass Federal 215 Mag primers used in all loads Pro Chronograph optical chronograph 15' from muzzle (measured) - with light shields No accuracy testing just trying to find a velocity node to start with going forward. I am conservative in pressure stops, I stop when I see ejector or even slight bolt lift pressure. RL-16 62.0 = 3030 63.0 = 3079 64.0 = 3129 65.0 = 3182 - slight bolt pressure STOP IMR4064 57.0 = 3030 58.0 = 3072 59.0 = 3137 60.0 - 3182 - moderate bolt lift pressure - STOP Varget 58.0 = 3051 58.5 = 3072 59.0 = 3093 59.5 = 3127 - very slight bolt 60.0 = 3144 - very slight bolt 60.5 = 3144 = moderate bolt - STOP I went a little further than I normally do with this load. W760 65.0 = 3100 66.0 = 3152 67.0 = no velocity? 68.0 = 3244 This shows more promise and had an extra 4 pieces of brass from a lot to use up so I need to go further with this powder. H380 61.0 = 2989 - no clue 62.0 = 2989 - no clue 63.0 = 3155 64.0 = 3167 65.0 = 3205 66.0 = 3244 66.5 = 3284 - moderate bolt lift - STOP RL-17 66.0 = 3300 - moderate bolt lift - STOP So I guess I started a wee bit high for RL-17 but thought it should have been fine based upon my RL1-17 load for the 166 HH. So after all of this I really didn't see the huge gain over the 166 HH where I get 3250 with RL17 without pressure at all. In fact, I topped 3300 with RL17 on the 166 as well. I still have to do some more work with W760 to see where it tops out but it is hunting season and even this data is over 1.5 months old, just didn't have time to sort through it. I hope to get back at it after January 1st plus will have range to myself when it is 25 degrees! [/QUOTE]
