Results: Approaching Manual Max. Load Data
I�ve been reloading some 165gr Partitions over Vihtavuori N160 powder in my Remington 700 30-06. Book max. load for a 167gr Lapua Scenar bullet using this powder is 63.7grains for 2901fps from a 24" barrel. There is no data listed for the Partition bullet.
I worked up a load using my own pressure signs of sticky extraction, heavy bolt handle lift, flattened primers and primer pocket looseness. I got to 63grains before stopping without seeing any of the above signs. I thought I had my load settled.
Saturday I returned to the range with some more reloads to run over my friend�s chronograph (Pact 1XP). I was quite surprised to see an average of 2970fps with low SD. The barrel on my rifle is standard factory 22�. Temperatures on both days were in the range of 17c to 21c (about 62f to 70f).
I�m a little worried that the velocity figures are telling me I�m probably running pressure too high. Would this a good conclusion? Or is 2970fps quite possible?
Thanks for any observations / comments.
