Doing a little prep on some .308 Lapua brass.

[NF1E]

Doing some brass prep today myself. No tumbling being done until after 5 or 10 loadings. Brass .308 200 cases is Lapua that was neck turned for truing only then fire formed to the chamber. Today annealing, sizing neck and should bump to .001 and then trimming, setting neck tension with mandrel, primer pockets K&B uniformed. I do enjoy this stuff on a rainy day. When this is all set I will be loading 115gn Berger flat base target bullets over 46 gn of Varget set off with 205M primers. This is my sub 1/4 moa ammo. Has been running at 3025 fps out of a 26" X-Caliber SS 1-10 bull barrel. Whatta Hobby!

Ok, first.... let me commend you for spending Easter doing something awesome! Lol (Happy Easter!) Why are you waiting until 5-10 loadings before tumbling?

Brass never hits the dirt and I can't see where tumbling would be a benefit early on. Just a choice with these batches. I do normally tumble and anneal for each loading but these are test batchs I am doing a couple of things on. Also have batches of new Alpha , Peterson and Starline in the test for the halibut. Looking, for myself, just to see if carbon in the case makes any difference in any of the monitored data. Lots of time on my hands in retardedment and enjoy answering some of the questions that have entered my small mind over the years. Whatta Hobby!
