[QUOTE="Steve Shelp, post: 33077, member: 22"] Ric, I've been a 1000yd BR shooter for years and I have always said and agree with everything said above. Many many times I have been asked 1000s of questions about this and that, but I have always said the most impotant thing is finding a good powder, primer, bullet, seating depth, combination first and formost. To many times I've seen someone claim they have a grouping problem and want to start using all the "tricks of the trade" to eliminate the problem when it is probably an issue with the original load combo, WIND and/or MIRAGE, or a rifle/shooter issue to begin with. BR tricks are not going to fix those. The tricks will make the "problem" better but it won't fix it. And savings in group size due to the "tricks" are usualy masked inside of the original problem and you won't see them. But mathematically we all know it helps. It's just whether you can see the results with any statisical certainy. In BR the loose rule of thumb is: Until a HG is shooting 6-7" 10 shot groups in predictable conditions you need to keep working on your load in general. Then once you reach that plateau, then you can start tweaking it with all the tricks. In LG with 5 shot groups that range goes down to 4-5" range. But I will go as far to say of the list from Ric above, if you are going to do one thing it would be to measure the base to ogive length variation. That will get rid up/down with a small amount of time and equipment in any rifle at longer ranges. Steve [ 04-16-2004: Message edited by: Steve Shelp ] [/QUOTE]
