I did have one rifle.no, two, cut with the throat length determined by dummy rounds provided. SOmething in the order of ogive + 0.002" or so, very short.
I found no accuracy difference with these rifles, but did find in comparison to a long throat rifle that Sierra bullets, at least in 22, 30, and 33 caliber, are very length ( jump) tolerant with little or no accuracy degradation, and no appearent bullet deformation as evidenced by longer range groups.
Hornady Amax bullets as one example haven't proved so forgiving in that regard.
My shooting partner has tried a couple other brands, some that are tolerent, some that are not.
