Been playing around with my original Winchester 1895 TD Deluxe a little bit before the snow flew this year. As soon as I get enough melt to be able to drag all my equipment back to the range, I'll be back at it. Started out with some Hawk bullets, but they didn't work out to well, then went on to Woodleigh 300 gr SN moving around 2150 fps, which is really darn close to the original factory ammo and was done with H322.
I got into casting some pistol bullets for my S&W 625 JM, S&W 27,and S&W 57, the rifles followed shortly after starting with the .405 Winchester. Amazingly enough the barrel slugged at .4125 and I got a sizing die at .413 for my Lyman 4500. I was having difficulties finding a decent source for gas checks, so I went to Pat Marlin and order a PB Checkmaker and then requested (Tom?) Accurate Molds to make a PB 411325 mold for me.
The PB Checkmaker and the mold arrived in fairly short order,so I began to cast boolits from COWWs that had a BHN of 12-14 after 10 days AC. At that point I would size and check the boolits, then heat treat about 50 at a time at 425F for 1 hour and then immediately dump them into room temperature water for cooling. After 7 days these have a BHN of between 18-22, depending on if they were in the middle or on the edge of the basket and then lubed with a 50/50 of beeswax and NGLI.
This was the last target I shot before the snow flew which is not the greatest, but am still working on the loads.
Still have some Woodleigh's left paired up with some of the cast loads for a little comparison.
Like I said, still working on the loads and may even switch to a different powder and may even try sizing them to .414. I do have a Ruger #1 in .405 Winchester, but have that reserved for some Barnes 300 gr TSX I worked up to a chono'd 2550 fps and have only been able to recover one fully flowered slug that was buried about 24" into a wet sand berm from 100 yards. I don't believe penetration to be too much of a problem with this load. Good luck and stay safe.
