[QUOTE="Derek M., post: 711265, member: 2693"] Shot yesterday morning and confirmed foul shots were necessary. I had 2 bullets left with 58.0 grains of VV N165 so I used those to foul the barrel. Curiously, they touched each other at 100 yards where the last range session a three shot cluster formed a 3/4" group (but again, that was on a clean bore). So I took 21 loads to check seating depth. All were 57.5 grains of powder. I did not clean the barrel at all. 5x seated as before at 3.30 5x seated at 3.34 5x seated at 3.32 6x seated at 3.33 (for 2 three shot strings) The rifle definitely likes the depth at 3.34 best. The 5 shot group claimed a 3/8" group so that will do. The rest did very well and to my satisfaction. All under or at 1/2". So the 280 and 7mag are going to Colorado in a couple of weeks. I'll take the 280 to KY on the 10th for the opener, then hit the road to CO the next morning. [/QUOTE]
