Not long back I was asking a question about the Swiss Precision Powder 210. No one knew anything about it, only it's like IMR 4198. I have a 32" BC 45-70 and I use H4198 and IMR4198. As most know by now, powder; primers bullets etc will be going up soon. I talked to Chris Lee at Widener's. He stated it was very consistant and extremely accurate in .223; 5.56 and 30BR. I have a 30BR and I only use H4198. He was not sure about the 45-70, only try it. And at less than $15.00 lb ($119.00 for 8lb, I got it) Will I did try it in my BC and it has the same fps as H4198 in the 45-70. I shoot silhouette and try to keep it down to 1250 to 1300fps. (This is with a 465 bullet.) Now I do not know about the .223 etc but I will try it also in my 30BR. All I can say is, with me, (45-70) it is a very good powder and very accurate. (This was with a light load to keep it at 1300fps I have not tryed yet for a hutting load) Give Widener's a call. Thanks beng
