[QUOTE="Jcann, post: 3149326, member: 33119"] I enjoy your feed back swampratt. I think both of us enjoy hand loading and the frustrations that come with it. I don't think you need to shoot an OCW at 200 or even 300 yards. I'm not looking at group size necessarily but at POI. Are the shots grouping in the same area of the target? Say at the 5 o'clock or 6 o'clock. If you notice the 65.0 and the 65.3 gr group are kind of scattered but the 65.6 and 65.9gr group are clustered in the 5 o'clock/6 o'clock position. This tells me that I have probably hit an accuracy node. What this means for all intent and purpose is, I can have one charge weight, say 65.8 and due to slight deviations in pressure for one reason or another chances are the group at distance will only deviate slightly if any at all. Especially when you take into account the human factor and atmospheric conditions. Granted you still need to keep your SD/ES as low as possible and that's what I will be checking this weekend. I've shot this rifle with the same load for over 7 years, almost exclusively with 180gr Berger bullets, H1000 powder, and a charge weight of 65.8gr. This loading is the Federal Gold Medal Match ammo for my rifle. It doesn't matter if the Berger bullet is the VLD Match, Hunting VLD, or Hybrid. They all shoot consistent with 65.8 grains of powder. The only time I shoot for groups are when I'm zeroing my scope (at 100yds). I find group shooting pointless in a hunting situation. Deer and antelope have about an 8" chest kill zone. I shoot a 10" steel gong at all distances. If I can consistently hit it out at distance I know my load is doing what it should. I also shoot 5" steel disks out to 500 yards.

If you're having a 12" dispersion in group size between 100 and 200 yards there is something big time amiss and it has nothing to do with an OCW. Just because a round groups great at 200 yards doesn't necessarily mean it will group great at greater distances. If you have high ES you'll start to see vertical stringing in greater distances due to variations in velocity. [/QUOTE]
