Big Al Posted October 19, 2015 Report Share Posted October 19, 2015 I picked up a lovely little Sako 75 recently in .222, the plan is to shorten it to 18" and use it as my carry/truck gun. It was described as nearly new with a very low round count and when it arrived I wasn't disappointed. Initial load development looks promising although Im running it slowly as it was to be more of a Hornet replacement than a full blow .222 Link to comment Share on other sites More sharing options...
onehole Posted October 19, 2015 Report Share Posted October 19, 2015 Nice one Big Al,,,great little calibre,,,,,I,m on the same mission at the moment and looking for a 222/3 to chop down for something a bit handier than my leggy lumpy but lovely 6BR,s.....Had two sako 222,s in the past and with the 40 grainers I believe I favoured R7 and Vit 130,,,,probably worth a try especially when you shorten it? ,,,,,,,,,,,O Link to comment Share on other sites More sharing options...

After doing a bit more research this evening the Hornady manual gives loads using both Accurate 2230 and H335, both of which are very slightly slower than N133 and they max out around 25.5gr so I imagine Im well below max at the minute. My barrel is currently 22.5" and I was hoping to go down to 18" so maybe I will need to go to a faster powder. Im not looking for a lightening bolt from this rifle, its more of a sub 250yd rifle so maybe this N133 load will still work? Now I just need to find the balls to get the hacksaw out!

Si-Snipe Posted October 24, 2015 Report Share Posted October 24, 2015 Is Dave Folwell not doing the barrel trim for you? Link to comment Share on other sites More sharing options...
Si-Snipe Posted October 24, 2015 Report Share Posted October 24, 2015 Above 22.5g there is a shifting POI which denotes harmonic instability. It may change above the max you tested if pressure was low enough to go higher. Worth looking at. Looks a good shooter. Link to comment Share on other sites More sharing options...
Big Al Posted October 24, 2015 Author Report Share Posted October 24, 2015 I can see me doing a new load with something like N130 or maybe even N120 Link to comment Share on other sites More sharing options...
Alycidon Posted October 24, 2015 Report Share Posted October 24, 2015 Suspect N120 will be a bit to fast and generate some pretty hot pressures, perhaps someone with Quickload can do the maths. A Link to comment Share on other sites More sharing options...
