just out of curiousity went back and looked at some of my notes.
out of a buckeye shooter blackhawk in 10mm:
with 200 grain xtp And AA#9
1.1318
2.1302
3.1305
4.1290
5.1301
6.1295fps
out of a redhawk .41magnum with a 215 grain bullet
1.1289
2.1381
3.1173
4.1285
5.1277
6.1242 fps different powder in the redhawk, and cast bullet
I got to thinking about this a little more, and i would summarize it this way. With the .41, you can use much heavier bullets than the 10mm. With the 10mm, you can go down to 135 grain, but i haven't seen any 250 grain like with the .41mag. And the 10mm casing is just more efficient.
I thought i might add to the above for references sake:
this with a glock 20 10mm with hornady 180gr xtp and AA#7 first column is with a 6inch KKM barrel and the second column with a standard glock barrel
1. 1268 1167
2. 1265 1188
3. 1291 1198
4. 1263 1173
5. 1277 1178 feet per second on chrony
with a hornady 200gr xtp the first column a kkm regular barrel on a glock 20, the second a six inch length kkm barrel on a glock 20 using AA#9
1.1212 1298
2.1211 1285
3.1218 1266
4.1213 1283
5.1224 1265feet per second
