[QUOTE="4ked Horn, post: 98941, member: 11"] Here it is. The raw target. Components are new win brass, wrm primers, 250 gr SGKs, H4831sc powder. Rifle has the rear tang and front of reciever and lug bedded. BBL is free floated but not by much. Rifle was shot from front rest and rear bag. Trigger pull is a light 3.5 to 4 lbs (it will be used while traveling cross country sometimes). Rem 700 stainless. 40 deg. 3100 ft ele. mild 90 deg cross wind (5mph or less) coming from l to r. 10 rounds through bbl since last cleaning prior to starting test. No less than 1 minute between shots. Often more. [img]http://img.villagephotos.com/p/2005-2/944219/338ladder.JPG[/img] Here is the graph showing the actual height relation of the shots. The first shot in the above picture was a test shot that was given #1 so shot #20 is actually #19 on this chart. [img]http://img.villagephotos.com/p/2005-2/944219/Shotheight.JPG[/img] Here is the velocity graph. The red vels (8,18) were "no reads" so I put them between ajacent shots. The green vel (16) was identical to shot #15 and we didn't notice if the chrono beeped or not. [img]http://img.villagephotos.com/p/2005-2/944219/Shotvel.JPG[/img] Velocities are as follows: 1 2341 2 2320 3 2365 4 2398 5 2413 6 2422 7 2476 8 no read (2500) 9 2526 10 2559 11 2554 12 2568 13 2583 14 2603 15 2645 16 2645? 17 2626 18 no read (2640) 19 2660 OK lets see if we can make heads or tails of this. Maybe a reccomendation on a next step. [/QUOTE]
