No i havent tried them and according to Noslers site they dont make a 10mm Partition although they may have in the past. They used to make a 9mm Partition so who knows.
Currently they offer NO more Partitions for handguns at all, only rifle bullets. The current 10mm 180gr is the "Sporting handgun" line and is not a Partition.
If you found some they will likely be the last ones available for a long time if ever.
To answer your question though, if there is such a bullet....im sure it would do VERY well and would love to know where to buy some. As Sabotloader said though. If you are paying full retail price, i would consider the Lehigh 185gr option first or save some money and use the GoldDots. I have total confidence in both for Whitetails. Both also shoot very well in both my 45s with a edge on long shots (150yd+) going to the Lehigh.
Im not doubting you, ive just never seen them anywhere. So i would double check and make sure they are Partitions, The Sporting Handgun line are far different with a soft lead core with a tapered jacket and very reasonable price.
The only reason i have a large stock of 44 and 45 Partitions is i found them for a little less than half of retail cost and they are discontinued according to my sources. Noslers new site doesnt even list any info on them.
