Thread: Load dev for a mates .284win Tikka

Here is the initial load testing for a mates .284win tikka 21.75" (was 22") that he bought 2nd hand. The barrel is rather pitted, the crown and 6mm of the muzzle was rotted out rough until i trimmmed,recrowned and rethreaded it.
Its pretty lightweight at 3550gram ready to shoot (incl suppressor).

I used GRT to simulate some loads and pressure. The chamber must have been cut with a match reamer throated for 175-180gr class bullets. The 162gr eld-m seated perfect above the neck/shoulder junct is still jumping 0.100", i like about 0.050" for eldm and eldx pills in other cartridges.

I was trying 3 powders with the 162gr eldm seated to a COAL of 3.150". All are ladders going up in .2gr increments. I shot the ladders round robin starting from the lowest charges (ie 2209,2213, sf, sf, 2213,2209,2209...). Numbered shots on target are actual load/shot order for each powder ladder. Recorded on my camera.









The 2209 appears to be the most consistent powder for POI across the charge spead. The SF wasnt bad either so I will have a run with some more of those, probably continuing the ladder charges a few more steps too.
