[QUOTE="swampratt, post: 2342674, member: 15054"] The case just does not hold enough powder to get there.. If you load a max load of H4350 you still will be shy but pressures will be closer in check than say a faster powder. All you will achieve in your quest is an eroded throat. Or possibly busted parts. Be prepared to fix broken extractors. Flattened primers are not a good sign of over pressure..as some primer cups are soft..like the 210M federals. Now a tough primer is the CCI #34.. that being flat and cratering would be a good sign that pressures are getting up there. I have a .308 savage 10FP bull barrel and 24" long and accutrigger... That one will get upper 2700 fps from the 178A max. With my 30-06 and 22" barrel i can get just shy of 3000 fps with the same bullet.. Choose a bullet with a high BC and find an accuracy load...The 155gr sierra palma 2156 is a good one. Now not for shooting deer though..Tried it and it makes a tiny hole in and a tiny hole out.. did the same with a hog. I got 3176fps with that bullet in my 30-06. Are you needing the speed for long range shooting(what is the distance) or are you chasing speed braggin rights. I was chasing braggin rights for speed then gave up as it proved nothing and was hard on my brass and weapon. Now my accuracy load for the .308 is upper 2600fps and 165game king HPBT. shoots .4" groups at 100 and .888" at 226 yards. The 30-06 gets a 150 flat base and will shoot .75moa out to 300 yards. just under 3000 fps like 2936 fps on cold days . So are you plinking ,,,hunting,,, or long range shooting???? [/QUOTE]
