[QUOTE="todbartell, post: 27586, member: 1435"] I have used this RL15 powder in my 260 Rem for 100 gr. bullets. With the 100 gr. Nosler Ballistic Tip bullet, I could get pretty good groups, 1" or less. This is the first time I've tried it with a 120 gr. bullet. Yes, my barrel is quite slender. I let it get almost cool, just slightly warm to the touch. I fire 3 shots within 2 minutes for my group. But it is often my first or second shot that is off. I have tried RL19 with this bullet last summer. Seated .030" off the lands, I got a 5 shot group of 1.5". CCI BR-2 primers is what I used. I have since run out of RL19. Just sort of using up what powders I got left. So, this morning, I loaded up 20 more MatchKings. I have a little Winchester WXR left, the only slow burner I got other than 7828. 49.5 grs. gave me 2909 fps avg. for 10 shots. ES was 57 fps, AD was 14 fps. Bullet was seated .030" off the lands. Accuracy was no better than my previous RL15 load. [img]images/icons/frown.gif[/img] My first three groups of 3 shots went into 2.17", 1.55", & 1.13". In all three, there would be 2 holes within .8", then a flyer. But not always would the 3rd shot spoil the group. [img]images/icons/confused.gif[/img] I then backed off again to 335 yards, tried two more groups. First one went into 2.92" (not bad), second was a wide 6.38". Used my last 4 shots to blast 4 2L Coke bottles filled with water. 3 out of the 4 were knocked down. Upon inspection, I hit all 3, dead center. Can't believe that! The one that didn't fall was hit high, a little below the neck. Just lost the water up to the hole. Hey, about the holes in the bottles.

Looking to salvage a decent load with this last stab at the box of MK's. [img]images/icons/frown.gif[/img] P.S., the wind was very light tonight, and I also did set my AO for the range I am shooting at. [ 06-24-2003: Message edited by: todbartell ] [/QUOTE]
