I have used them both, and think I have made the decision for my bores, I like MMP. What do ya think?

I like the MMP also.

MMP.

I use both. I have different projectiles that work best with each of the sabots. The MMP's are more forgiving for the store bought projectiles, but I use the harvesters on the ones I cast and purchase.

I use MMP sabots that I buy from them directly. That way you KNOW what you are getting!
