Shooter world powder

[358WCF]

I found that identical load for my 06. with sw4350 to imr 4350 same point of impact

Did you chronograph the SW vs the IMR? The lot of SW 4350 I had was aout comparable to some IMR4831 in my closet. It's that much slower in the 4 varying size cartridges I tried it in.

See my results for Lovex S070 (SW4350) v H4350 here:

http://www.targetshooter.co.uk/?p=3657

Note also the findings of Handloader magazine's 2003 side by side test of H4350, IMR-4350, and Accurate Arms XMR4350 reported on therein. (2003 XMR4350 = Lovex S070 = SW4350, all the same product from Explosia a.s. in the Czech Republic.)

In my tests, Lovex powders are serially slower burning than reported or as used with default values in QuickLOAD. Lovex S062 (SW 'Precision') also worked out the same way compared to VarGet in 223 Rem with the 77gn SMK, with the sole exception of S060 (the former Accurate Arms XMR2015 - not adopted by SW AFAIK) is the sole grade so far that works out close to expected loads/velocities.
