A few months ago I purchased a box on the Lehigh 230 gr. .451's with the hope of shooting them sabot-less. Well that got dashed quickly once I realized the knurling is too much to get past the crown. Bring on second idea, I bought a box of 185 gr. .451 XTP just to check barrel. They load with thumb pressure and will stay but will shake out. I then bought a Lee .452 sizing die in hopes of bringing the knurling down enough to load. Still too tight, ran them through the sizer several times. My question is how much spring back is there? If I go .451 will they come out at .451 or will they spring back a bit more.
