Re: 180 gr Hornady RN and Sierra 180gr RN Subsonic?
I think you could probably get away with it...but that is a thought and only just that. As with any changes to your reloads, back down or in this case being subsonics, go up in charge and work your way back down safely. Especially before putting the can on, make sure they're stabilizing properly.
I know that the 220gr Hornady and the Sierra 220gr RN are pretty similar in length. As far as the rest of the construction of the bullet and specifics to Ogive length I'm not sure....

Thats kind of what I thought, since the sierras seem to be more readily available at the moment I think thats what I'll try. Just makes me nervous when you put the can on with a new load.

Absolutely, shoot them with the can off and make sure they make round holes in the paper first. If you have a chrony it would help to see what your velocity is as well.
I don't know what your temps are like where you are, but right now in the winter my subsonic loads that were subsonic in the summer/fall are not subsonic in below freezing temps here in AK. I've had to re-work my subsonic loads down some. Even though they would normally be stable at 100 yards, now due to the lower temp they tumble at 100 yards. Up close they leave the barrel stable but either they are tumbling before or on impact at 100 yards. I've used 208 amax, 220gr Hornady RN and the Sierra 220gr RN with the same powder charge. But again, my loads, my rifle.
Good luck!

Don't have a chrony yet, been looking at the oehler. I had read a lot of loads on here where guys were using in the 10.2 - 11.0 gr range of trail boss, but out of my 20" barrel 9.6 is what I had to take it down to to keep from hearing the sonic crack. I originally shot several test loads at 100 yrds to make sure they were stabilizing. Even went as far as to shooting them into a 4x6 to check even closer that they weren't tumbling. Ended up looking fine and went for it, but boy was I nervous.
