Pharmseller, do you normally reduce your loads a bit when using WLRM primers? I tried using them in my 358 Win with slightly reduced loads of Ramshot TAC and my normal 225 grain bullet and my group sizes seemed to increase a bit.


Nope, no reduction.

Here’s an example of my experience with WLRM and CCI200, with 120 BT in two Tikkas. Each Tikka shot a three shot group with each load.

Comparable accuracy, slightly better velocity with the WLRM. Either is fine if you are limited by availability.




P

Is the POI shifting that much, CCI-200 compared to WLRM?

That's a fair amount of velocity increase just with mag primer.

Have you tried Fed 215's or other mag primers?
