pork chop Posted June 10, 2013 Report Share Posted June 10, 2013 hi buddy ,hornady 7th edition states 20.6 gr of vit 133 as a starting load and 23 gr max that for bullet weight of 52/53 gr.my son uses 25.8 gr in his tikka 595 and their very accurate .those loads have been worked up in his rifle and do seem very high to the hornady max but these show no over presure signs at all and brass still ok after 4/5 reloads Link to comment Share on other sites More sharing options...
Rammer223 Posted June 10, 2013 Author Report Share Posted June 10, 2013 Hi pork chop hornady manual does seem to be very conservative at that ,I will work up steady and see how things look what velocity is he getting 25.8? Regards lee Link to comment Share on other sites More sharing options...

achosenman Posted June 11, 2013 Report Share Posted June 11, 2013 FWIW I use 52 Amax. They weigh in at 52.2gn My QL workup for around 50,000psi load is as follows. (QL is set for a max 62,366psi) N133@ 25.1gn Lapua Case 30.7gn internal H2o volume. Trim length 1.755. Primer pocket depth cut to .124 Neck turned to .0125 (My chamber is a custom tight neck and long throat) CCI 450 primer seated at .003 crush. I neck size with a Redding Competition die using a .246 bushing. I then run a Sinclair neck turning mandrel with dry graphite lube to set the internal diameter. I leave the lube in place for bullet seating. COAL is 2.321 from base to tip. I actually use a comparator and use .020 from the lands. This shoots at 3382.2 FPS into a gnats dangly, with an ES of 7fps. I am on reload number 14 with this brass and I do anneal. It's still going strong. The action is a Stiller Tac 30 but the firing pin has been bushed. This load is fine in my rifle, yours may be very different so use the above as a rough guide at your discretion.
