Load dev and supressors

[philcox]

I am developing a load for my TIkka 300WM. However, it will have a suppressor added sometime next year. My question is if I will have to redo my load dev? OR it is most likely a "POI" thing and not a "grouping". Any insight is appreciated. I don't want to spend ton of time on load dev, just to have to repeat.

Thanks

Just POI. Groups may even tighten a bit

Depends on the rifle and where you end up in load development. If you are near max pressure before putting the can on, the can could send you over max (I have had that happen). If you end up in a lower/slower node then probably a non-issue.

It may take a slight change in OAL seating. You’re adding a weight to the end of the barrel. Typically, this makes the barrel a little more forgiving but if you’re on the wrong end of the tube, it can get worse. If your tune is good but the ES is bad, the extra weight can help minimize effects of ES, which is why a lot of loads will shoot better. It’s unlikely that the best load you can develop will be much if any better.
