And 78.5 in the middle with two 79 grain groups on the outside.

Biggest fail of 2014 so far... http://www.longrangehunting.com/foru...ea-ftf-128972/

My guess on W3P .308 230 Grain Bullet: G1 .740-.755

    Looks like it is starting to not like it at 79. I would play with the 78.5 seating as you indicated. I shoot 80 with my 208 SXR's and it shoots great......Rich

    Did some more shooting today, the pics have load info. I think i will move out to 300 yards with my .041" load and 78.5 grains of H1000 but try to fine tune my powder charge by a hair, i am thinking 78.3, 78.4, 78.5, 78.6, and 78.7 and see how they shoot. I hope i get my magneto speed soon, i cant wait to see what i am running for velocity.

    Around .045" off the lands is looking pretty good. I think I would try .060. .070, and even .080" off and see what happens. With a 28" barrel you are probably in the 2900 fps range?.......Rich

    I have a 26" tube. I will give .060, .070, and .080 a try, it looks like wednesday should be nice, i will try to shoot them then.

    Groups are looking pretty good, especially for a bonded bullet! The 215 Bergers would probably group even better but I understand you are trying to develope the ALR as your hunting load.......rich

    I chronoed the 210 ALR on saturday and got 2877 fps from the magnetospeed. That said, i am going to give the 215 hybrids a try, if i can find any before hunting season. Rich, if you could give me some load info via pm for your 215 load, that would be great. BTW the 210 ALR at 2877 tracked perfectly out to 750 yards when i use MMERSS's G7 BC of .318
