I was wondering if anyone has tried Lapua 308 Palma cases in subsonic 308?
In an attempt to separate my covert loads, 178Amax and 208 amax look the same when loaded, i decided to grab some 308 Palma cases for the subs. To make it even easier i ran some Remington 7 1/2 primers in the palma cases so they are all brass looking form the bottom.
I went to the range today and fired a couple of 50m groups (10.8gr, 11gr & 11.2gr of Traillboss) to see if there was any difference and the results were amazing. The 11gr charge was still the most accurate but the group dropped by over half. I went from about 0.5" to a ragged hole.
I was wondering if it was the change of primer brand or size that made the difference.
