Just a suggestion but here's a simple formula that might be a solution for the 308 vs the hot rod cartridges debate.
I'll call it the "Ballistic Coefficient Muzzle Velocity Factor" - BCVF
It's easy....BC x FPS divided by 1000.
Cartridges equaling a rating of 1.5 or less go into what amounts to 308 or ballistically similar cartridges. Over 1.5 go into the ballistically superior cartridges category.
Examples...
223 with 77 grainers. .4BC x 2850 fps divided by 1000 = 1.14 BCVF
308 with 155 grainers at 2900 fps divided by 1000 = 1.334 BCVF
308 with 168 .47BC x 2700 fps divided by 1000 = 1.269 BCVF
308 with 175 .515BC x 2650 fps divided by 1000 = 1.364 BCVF
243 with 105 - .545 x 3150 = 1.71 BCVF
260 with 140 - .6 x 2800 = 1.68 BCVF
7-08 with 168 - .62 x 2750 = 1.705 BCVF
6.5 SAUM 140 .62 x 3100 = 1.922 BCVF
7 SAUM with 180 - .67 x 2900 =1.942 BCVF
FWIW, I think a concept similar to this has merit. Similar to power factor in pistol sports.
However, wind is the decisive factor here. I think we can all agree that gravity is fairly constant so elevation is much more predictable than wind. Wind is typically what gets us, and I think this is what Frank and others were also eluding too. With that said I think you will always have gamers, guys that will run at 2875 or 2900 if you limit the speed in their division at 2850. Some of this, to a point, will happen depending on powders and atmospheric conditions as well. Personally I don't think 50-100 feet per second will make me shoot any better or worse. I started with a R700 308 1:10 twist rifle, then 30-06ai and 7RM and a host of other calibers before going to 260Rem and finally 243win. My 260 rem was shooting a pointed 142SMK at 2850-2875, my 243 is shooting a 105 hybrid at 3080. Why 3,080? Because that's currently where my gun shoots the most accurate. I've never had a gun that would shoot to its highest accuracy potential at the top end of the velocity scale without pressure signs and excessive wear on brass. I've learned my lesson there.
243 win, 105 hybrid @ 3,080fps, DA of 1500, temp 70, 10mph wind @ 90* I get 7.0E/1.8W @ 1K.
260 rem, 140 hybrid @ 2,800fps, DA of 1500, temp 70, 10mph wind @ 90* I get 8.1E/1.8W @ 1K.
Exact same wind.
I would hate for this sport to end up regulated to death like an IPSC comp. We have enough to worry about without adding a bunch of rules on top of everything else. I honestly do not agree that someone shooting the same caliber and bullet 100fps faster has any clear advantage. We are not shooting from benches. We are shooting from unstable positions, in varying wind and light conditions. We do not all shoot the exact same stages at the same time in the same conditions, that is a given in any competition. There are WAY too many variables to make separate divisions based solely on velocity.
To me, this is like saying, if you neck turn, weigh your powder on a prometheus, point your bullets, etc. you have to be in open division. Only factory ammo can compete in "X" division. In the end some people practice more than others with what they have...practice is what makes a better shooter not just the caliber. Do I agree that someone shooting a 7WSM from a
prone position has an advantage over someone shooting a 223 @ 1K yards? Sure, but only to a point. The advantage is lessened and may even be in favor of a gas gun 223 shooting from a wobbly barricade at 323 yards over the 7wsm. To me caliber advantage plays a little higher in matches where longer shots are possible and the majority of shots are taken from stable positions. Someplace like K&M where you are tested on positional shooting more than prone, a whizbang caliber loses some of its advantage and the shot comes down to more skill than caliber.
No one is forcing anyone to run a certain caliber. Caliber, velocity, bullet, barrel twist, etc., etc. are completely up to the individual shooter. That's what great about the sport is that you can literally run just about anything so long as it does not exceed the matches maximum velocity and caliber. Not to pick on him, but you could give George a 308 shooting a 175smk at turd velocities and he would still easily come in with a top 10 finish at just about any match I could think of, especially one that has a lot of positional shooting.
Just food for thought.
