I'm scratching my head some what....
Worked up a load for my 308 bushpig last summer with H335 and 150gr nosler BTs. Found an accurate load and loaded up 40 odd rounds. All components the same.
Have fired 30 odd rounds since without any pressure signs, chronograph them doing 2820fps.
Went to check zero yesterday after having the stock off and fired 3x of the handloads and had stiff bolt lift and slight ejector marks on all 3 rounds....
Any idea why this might happen?
Only things I can think of are:
- I fired 3 factory rounds 5 min beforehand and maybe the chamber was a bit hot? Was a cool day though. Also load was developed in summer and I went 1gr higher than current load without issue.
-rounds have been carted about hunting for a fair few trips. Could they have absorbed some moisture? They have been in a pack or the mag most of the time. Not sure if moisture would have this effect?
Any other ideas?
