[QUOTE="Fiftydriver, post: 172011, member: 10"] Low extreme spreads are certainly what you want but it may not be as critical as many thing. I can not say how many customers I have had that came into my shop or e-mailed or called wanting to order a rifle. They will will say they want a top end rifle that will hold extreme spreads in the single digits..... I then as, wouldn't you rather have a tight grouping rifle and they often reply that if you get low spreads, you WILL have 1/2 moa groups or better. Simply put, and I will be blunt as always, thats simply BUNK!!!! If your dealing with small capacity, small bore BR rounds, it is possible to get extreme spreads in the single digits. When you jump up to a +90 grain capacity case in a faster twist barrel with a very heavy, long bullet driven to upper velocity ranges, it becomes much more of a challange to get those single digit extreme spreads. That is not to say its not possible, I have shot several strings through my 338 AM that had single digit extreme spreads. That said, the same exact lot of ammo tested at a different time would have up to 30 fps spreads........ In my opinion, in a chambering in the class of the Edge, if you can get extreme spreads under 30 fps, you will get fine accuracy at long range if the rifle like that particular load. If you can get better, great, if not, I would not sweat it. Group size is what is critical, not extreme spreads. Yes, long range groups will show velocity spreads for sure, how much, depends on how accurate your rifle is and how well you can shoot. I have shot 1/2 moa groups at 1000 yards with loads that have 40 fps spreads. I have also shot sub moa groups at 3000 yards with the same loads. I have also seen loads that were in the teens for extreme spreads not be able to hold better then 2 moa at ranges past 500 yards. Simply put, shoot the rifle at long range, if a load groups well, that is what is important, DO NOT pass on a load just because of extreme spreads that are a bit higher then you like to see. I had one customer come in complaining about a rifle I built him that he could not get under 15 fps extreme spreads. This was a semi heavy 300 RUM. We took the rifle out and I shot it at my 450 yard range behind the shop. After shooting three shots over the chrono and printing a sub 1/2 moa group, the customers only comment was, SEE, those three had a spread of 35 fps!!!! I literally had to put the group in his face to see how the rifle would shoot and to not get so hung up on ES. If she shoots, thats the critical thing, do not get to hung up on ES. In my experience, if a rifle likes a certain bullet, you will get fine accuracy with any load that gets you ES under 50 fps or less. Again, if you can get fine accuracy with low ES, great, but do not pass on an accurate load because the ES is a bit higher then you like. Kirby Allen(50) [/QUOTE]
