I do not know a commercial bullet casting outfit in your area, I live in Alabama and have been able to get 200 grain LSWC’s from Valiant Bullets of Bynum Alabama 256-236-5897.
Bullet weight varies a bit, so while the Valiant bullets are advertised as 200 grain, the ones I have weigh closer to 205 grains. This extra five grains is insignificant and could be the weight of the lube.
I have a Taurus with a 3” barrel and developed some loads with Unique. The pistol has fixed sights which are regulated for 200 grain bullets. Unique has performed exceptionally well in the 44 Spl with 250’s, so I tried it with 200’s. I have no complaints.
My plinking load is the 6.0 grains load. I suspect the 7.0 grain load is actually higher velocity than the Federal 200 LHP load. I shot some of that Federal but do not have chronograph values. It was not a high velocity load, I think it was under 900 fps.
