I really struggled with my loads on this one. My manuals all seem tailored to revolver loads (for 357 I really understand this) so I started with 158gr over No. 5. Simply would not cycle fully. In fact this load wouldn't even eject the spent brass.

So, I've stepped up to 7.8 - 7.9 grains of Unique. Bingo, cycles well and very accurate. I've not done the chronograph on this yet but will probably get busy on that in the spring.

The gun is an absolute "must have". Its high quality, well engineered and certainly draws attention at the range.

Good luck,
