wc 297 and 45 colt

[casey]

Has any one used WC297 in a 45 colt with 300-325grn loads? I talked to Pat McDonald and even though he was very busy, he said to use w296 data. Hopefully it will work out. I ordered a keg. He told me he is working on a 8-12 week backlog! Right now its running about $122.00 a keg. that includes hazmat and shipping.

casey,

I know you asked about WC-297 but if it loads at the same data as 296, I have loaded RCBS 45-270-SAA slugs which weigh in at 283 to 290 depending, using H-110. I am posting this just to give you an IDEA and this is NOT recommended data. I got up to 23 grains of H-110 (1218 fps from a 6.5’er) and I consider that to be at or very near maximum. Although I did not get sticky extraction, the primers looked much different than the same boolit and 9.0 (974 fps) grains of Unique—there was significantly much more pressure for sure! So that might give you a ballpark figure to use as sort of a reference if someone says a certain charge of your WC-297 is O.K.

Were you from in N.W. PA? I am from Clarion County…

Good-luck…BCB

use 110/296 data bit dont go below it. 297 burns very close to 296 but is just a tad slower. id start at 22 grains and see if you get consistant velocity readings over your chrono with that load and if not go up a half a grain at a time till you do. I only use cci 350 primers anymore with 820 or 297. there about the only primer that light it off properly in all temperatures.
