I would just advise you to go thru a good cleaning procedure using a copper and lead solvent with a new brass brush and pass it thru at least30 strokes. Then get some Buches Bore Paste/USP Bore paste and use liberally for another 30 passes. Swab'er out with some more solvent, dry patch, then oil patch and one last dry patch-Once thru only. Reassemble and get her ready for the next range session.
APP powder works best if compressed VERY Firmly-Press until it won't go no more! If those sticks are soft enough to be crushed during compression, then I would say go ahead and try it. If not, and the cleaning process has not improved regular stick performance, then try a pound of Loose APP 3Fg. Start at 90-100grns by volume and work up from there.
Bullets:
Encore has a tight bore shallow groves designed for sabots. If you try powerbelts use the 348grn type. The PR Duplex 195grn combo shoots like a laser beam in many rifles(for 50cal guns) and in 45cal guns try the 357/195 sabot combination :wink: If you plan on using a clean barrel/no fowling shot to hunt with, then swab with 2 damp alcohol patches (Both sides) followed by 2 dry patches between each shot at the range session. Then let the barrel cool down between each shot, working up your load in 5grain increments. Shooting 3-5 shot groups per load.
Powder:
Pinnacle/shockey's Gold, and Regular APP are all basically the same. Any one of these in
3Fg will do the job. (With Pinnacle being a little short on power by volume compared to the others, cause it is a tad larger granulation. I'd add 5 grains extra too equal the other 2 powders.)
Scope:
Take off all mounting hardware. Clean and Loctite the scope bases securely. Reattach ring bases, and Loctite these also. Place scope on lower ring halves and attach top ring halves--
Use No Loctite on upper ring screws! Bore sight or what ever it takes to square up the Reticle.
First time back at the range, just shoot at least 10 times before any serious load development.
This will settle the scope into the rings and mounts. Carefully check scope ring torque(don't over tighten) Then start your new load work-ups
Of coarse you may know all this already, forgive me for being detailed :-)
Hope this helps :wink:
