[QUOTE="Idaho Trecker, post: 1074998, member: 67706"] Its been a while since my last update... I made it to north Nevada and SE Idaho and completed my task of teaching some chucks acrobatics with the 270 Sherman and 165 Matrix!!! Needless to say the combo was devastating and I am very pleased with this gun. I finally purchased a chrono (shooting chrony) and am now able to get in the ballpark with my speeds. It looks like I was right at 3000 fps with the 165 matrix and 69.7 grains of RL 33. I jumped on the HBN train and got the rifle and bullets set up for it and the results were just like those of what others had posted on the very helpful HBN thread here on lrh. I made it out today and ran a ladder from 69.7, 71, 72, and 73 grains of rl33. I never ran into real pressure and the 73 grain load was compressed but I think I can get close to 74 grains crammed in there with the long COL and throat in my rifle. 69.7 2972 71 3071 72 3156 73 3151 I only ran this ladder at 200 yards (time constraints) but the vertical for 72 and 73 grains was only 1/4 inch. When I get time again I'll run some groups. Even if I end up at 3150ish I wont be mad about that since it still puts me with 1344 ft lbs, 1915 fps, and only 19.4MOA drop(with 200 yd zero) at 1000 yards!!! After talking with Elkaholic I picked up some RL26 and gave it a try with a ladder starting at 59grains up to 65 in 1 gr increments. 59 2935 60 2954 61 2998 62 didnt shoot 63 3056 64 3106 Cratered primer, click at top of bolt throw 65 3194 Cratered primer, click at top of bolt throw The ladder wasnt spectacular but not bad either; however I will be sticking with rl 33 with the 165 matrix for velocity and accuracy. I think if berger ever releases the 170 they have talked about or I can get some 175 matrix the rl 26 may be a good choice for me. [/QUOTE]
