Lehigh oops

[Atavar]

This is embarrassing. Some time ago I ordered some solid copper Lehigh Defense Extreme Penetrator bullets for 9mm and .45 acp.
The 9mm loaded beautifully and while I haven’t taken any to the range yet I am looking forward to shooting some.
As I was prepping the components to load the .45s I noticed that the bullets I purchased were .452, not .451. I don’t have experience with copper bullets and I am a bit worried that may be a problem.
My question is should I go ahead and load them with the .451 recipe or pass them on to someone shooting .45 Colt?

Shoot them as-is with standard load-data for solids.
Not to worry....

That is where I was leaning. I suspect that .451 vs .452 is within manufacturing tolerance anyway.

Maybe download 10% to be safe, unless you find a loading specific to those bullets, but they will work once you figure it out. Plenty of popular .452 loading for 45acp, usually in the +p range but I don't think it matters. Personally I would load those into 45super, or +p casings even if not at those high of pressures. I'm assuming they are the 200gr. I have a few boxes of Underwood in 45super with those 200gr XP rounds advertised at 1100fps. I think they are a bit slow for 45super, 200gr jacketed rounds should be at 1200fps for 45super, so I'm not sure if because they are solids that they increase pressures or that these rounds perform better at those velocities. ,+p are 1000fps.
I use a G30S that I sometimes will have the factory barrel and sometimes I use a KKM barrel with a compensator. When I need a woods gun I will either take the 200gr XP in 45super to run in the factory barrel, but if I have the KKM barrel installed I will take 255gr hardcasts from Underwood(which are .452)
