Muller Chokes has simplified things for you. We produce 4 different constrictions (and you can special order a cylinder choke--if you really must have one). Our 4 regular constrictions are referred to as: U1, U2, U3, U4 (for close, medium, far and farther). If you pattern them at the distances they were created for, you will immediately see how they shine.
Lets take the U4 for example. In my Beretta 303 with Fed 1-1/8 oz 7.5's at 32 yards the pattern, though impressive, is still underdeveloped. When I repeat the shot at 40 yards, this is what the patterning paper showed:
In summary, 188 + 135 = 323 total hits in 30" circle at 40 yards out of a total of 389 pellets (avg count from 10 shells). 323/ 389 = 83% pattern.
So, the U4 even though it had not developed fully yet at 40 yards produced a very even and impressive pattern considering that the definition of a Full Choke is 70% at 40 yards in a 30" circle.
IF you take the U3 at the same 40 yard distance you will see it absolutely shines with the numbers of pellets to the outer fringe evengreater than the U4. Why? Because I developed the U3 to be optimal at 40 yards!! The U4 is made to be optimal at 60 yards. The reason I am posting it this way is to help people understand that the even pellet distribution that Muller chokes provide is not hype and they do exactly as advertised PROVIDED they are tested the way they are meant to be used.
Up to now, all the good chokes out there offered a hot core with a very open fringe and that fringe was hardly consistent hence your golden BB breaks or clean misses when only off slight amounts. Well, that is no longer the case. You are no longer are stricken with hot cores and sparse outer fringes, so here is my closing statement: Please don't confuse more open patterns with even pellet distribution, because folks...it is far more advanced than that.
