38-55 Hard Cast questions

I’d like to ask a little advice and input – here goes:
My Father’s fine old Winchester M1894 is circa 1918, (I ran the serial number). It is in 38-55 and shoots the Winchester factory 255 grain loads, (the bullets of which I milked at .377), very well. Given that, it is logical to assume that .377 is the proper groove diameter, correct? (I haven’t yet tried slugging the bore & given the prior statements, I feel that in this case it may not be necessary, right?)
I just ordered some hard cast Hunter’s Supply 260 grain .376 diameter (Brinnel hardness 15) pre lubed bullets. I also ordered some Barnes Original .377 bullets in case the old rifle just flat doesn’t like the hard cast slugs.
My questions are: 1) Do you learned folks think these hard cast (advertised as rated to 1600 FPS without gas checks) will perform in the no-bore-leading category as long as I hold velocities at or below 1600 FPS? And 2) [grass roots logic here] since many white tails are taken with jacketed, expanding .223 and .25 caliber bullets that probably expand to around the unexpanded diameter of he 38-55 slugs, is it commonly deemed ethical to use hard cast slugs in the 38-55 to hunt deer, (given reasonable ranges and careful shot placement)? Your advice would be appreciated. Thanks in advance.

.376 or .377 bullets are NOT going to do the job. I'll bet you need a .380 cast bullet and larger if it will chamber. I shoot LaserCast .380 cast bullets in my 38-55 over 30 grs. of 3031 powder. Go to You Tube and search on JB vs 400 to see how accurate they are. It show shooting the 400 yard metal plate.
