.45-70 Nosler Ballistic Tip - coated vs. uncoated

I've worked up some loads using the "uncoated" 300gr NBT's that I got from SPS. At the moment, all they have are the "coated" (Ballistic Silver Tip) variety. For you that have loaded and shot both, any difference between the two, in terms of performance, velocity, POI, etc.?

Thanks in advance,
Brian

I cannot answer in the 4570 but I had the same scenario with some 3030 bullets. I instantly found a stellar load with the uncoated ones that wasn't quite there with the coated ones... and they were slightly slower with the same load but not much.
Then I picked up some leverevolution powder and the coated ones shot real good so it didn't wind up being a problem.
I think the only answer I can give you from my experience as maybe they will work for you and maybe you'll have a little playing around to do...
