[QUOTE="Trnelson, post: 1309627, member: 42308"] I finally had a chance to slip out to the range and see where this load sits. Atmospherics- 82• wind 160@15kts barometer 29.91"HG shooting direction 270• range 100 yards. I started with a totally clean barrel.I fired a total of five rounds all from an ambient bore. The magnetospeed chronicled a velocity of 2,788 fps with a SD of 3 for the five shots loaded with 76.0g Norma 217. This same load sends the 230 Berger at 2,740 with an SD of 8. I run into pressure with the 230 Berger at 80.2g so I think I should have some room to safely chase upward for a node. The bolt lift was smooth, easy and extracted without hesitation, and primers appear to present no sign of excessive pressure, but I will mic the cases to check them for certain before I load anymore. The last three bullets printed pretty respectably, considering having started with an un-fouled barrel and the stiff 17mph breeze. Before the next trip to the range I will load the last 50 Berger 230's I have for this rifle and will then see what some seating depth changes do for the grouping of the 225. Photo should be rotated 1/4 turn right... [/QUOTE]
