The light LFN will perform well, but I'd recommend the WFN in the same weight as the larger meplat will be much more effective when it hits, and espeically at the low velocities you intend to shoot them.
When working up loads, give Hodgen Universal a try. I believe it will be good for your 1100 fps top speed, and it sure will be for 900 to 1000 fps. The thing I love about this powder is it's lack of smoke, muzle flash, and minimum muzzle blast. All of which will make your dream of a pleasant shooting load more easily obtained. If you chronograph to know the speed, do it on a hot day and keep the top end real close to 1100 fps, so you can be sure the bullets don't start leaving supersonic with increasing temperature. This will also minimize the nose you have to put up with. IF THE CYLINDER GAP IS AROUND .002. If the gap is smaller than .002, lead scraps can make the cylinder turn hard, when using light loads, and if much larger, the powder blast which excapes from the gap is hard on one's ears. I've experimented extensively with cylinder gap and found that regardless of caliber, between 22 rimfire up to 44 mag. the .002 gap is optimum. I've never played with revolvers of larger caliber, but customers report it holds true with them also. -- If the cylinder gap is .004 or larger, the blast coming from it is horrible. I believe the laws of physics would say 4 times as loud as a .002 gap, or an .008 gap would release 16 times as much gas as a .002 gap. In my opinion from what my ears tell me, the blast is equal to exausted gasses. -- I stated that I did a LOT of experimenting with gaps. I won't delve into any more explaining about whys or how muchs. Just trust me. Have the large cylinder gaps fixed if you have a gun with the problem.
