Wow! been having fun with a new 45 Super i sprung up, just bought the Springfield Garrison from HilhamHawk, Thanks Troy, it has a forged steel slide and grip frame along with ramped stainless match barrel, i ordered some parts from Wilson Combat and directly from Wolff Springs.
The setup:
Full length Wilson Combat guide rod
28lb Wolff recoil spring
X-tra power firing pin spring that came with recoil spring
Wilson Combat flat bottom firing pin stop
25lb Wolff hammer spring
I Just got a 20lb flat wire Wilson spring and flat firing pin stop with thoughts of setting up for +P or Super loads. Is 28lbs and the other springs required as well to handle it? I thought i had ordered a 24 but I got a 20. Don't want to beat the heck out of it. I really want to get another 460 Rowland setup, but from Clark this time. But if I can setup for the 45 Super that would carry me through deer season.
Well I got the EGW flat FP stop fit nicely and the 28lb mainspring was a bit of a trick but I didn't launch any parts. Unfortunately the 20lb flat recoil spring won't work with my guide rod, it needs one .250" diameter so I had to order a round wire one which puts me back a week or so. While I was at it I ordered an EGW base for my Holosun 507C because I struggle to see the front sight anymore.
Looking for 45 Super data for the 200-255 lead bullets for Blue Dot, Longshot, Unique, Bullseye, 700X or 2400. Those are the only pistol powders I have access to currently.
Here she is, next to Grandpa (belonged to wife's grandfather who was Lt. Cmdr in WW2) which is a 1917 Remington frame with a Colt slide. The Kimber's new 20lb spring and EGW sight base came in and are mounted. Getting that original rear sight out was a bear but I mounted the slide in the Kurt mill vice and shaped a brass punch to drive it out with a 3lb hammer. No damage to sight or slide but it didn't want to move at first. I also took the opportunity to lengthen the throat lead with a Manson reamer so I could run the bullets out to 1.200"+. I may have gone a touch deep but it doesn't shoot any worse than before.
I loaded some extrapolated loads with Blue Dot and Longshot since they are similar in burn rate to AA7 and Power Pistol. Bullet is powder coated Lee .452 255-FP. Brass is shortened 460 Rowland because 45 Super is about unobtainium at the moment. The Longshot loads were way too hot, which was surprising. I won't mention the weights but I must have screwed up with the scale so I'll revisit when I have more time. Didn't have time for chronograph either. The Holosun was pretty well centered from the getgo and initial group on the upper bull was pretty decent from a shaky rest. The second Blue Dot group settled into a bit over 1.5" and made me smile a little. That should tighten up with better rest next time. I like the Holosun, this is my first experience with one of these type of optics. I also ordered a neoprene hood for the optic, which hasn't come in yet. I think this will work nicely for how I want to use it for deer season and hiking in general. I modified my M7 chest holster to accommodate the optic and it should be OK for now.
