I just loaded a dozen Speer .452 graphite coated 250 gr SWC into my Federal once fired cases. 6 gr Unique (weighed) and small pistol primers. OAL 1.275". I like the small primers with this load as the pressure is said to be slightly less. I loaded 3-230 gr Lead truncated cone loads intermittently in the cylinder with the 250's. I used 5.6 gr Unique in those. Large pistol primers. OAL 1.170. I could tell no difference in the recoil but, I fired at water filled 1 gallon jugs at 30 feet and the 255's blasted one jug in half while the LTC load split the backside of the other jug a bit...not as devastating as the 250 grainer. Both look like they will be heavy enough for hunting. I was surprised at my accuracy. I fired 6 rounds and counted 3 holes in each jug...in the front. Oh, no signs of excessive pressure. and all cases in reloadable condition. I got my testing in for today. It wasn't a long session but it took the edge off my need to smell burned powder.
