I had mine at the range today.
btw, mine's a ss in 1:32 twist
Anything I pushed in the barrel would do fine at 50 yds. I shot 240 Cheap Shots, 320 TC Maxi, and 405 buffalo bullet hp's.
At 100 yds, story changes. the 405's (being pushed by 80 gn triple seven), droped about eight, and drifted 8 right from poa. The 320 Maxi's did about the same at 80 gn, but at 100 gn, they seemed to only drop three, and drift three right.
The cheap shot (I was getting tired and only fired one) drifted 6 ish inches left, but was even on elevation.
Shooting.... I spit patch all the time, (so with a licked patch, 1 scrub with each side of patch, then 1 scrub with each side of clean, dry patch).
I was only firmly hand seating...not doing a rod bounce (Because a couple of the bullet types I was trying I thought might deform.
I tried loads of 70, 80 90 and 100 for the cheap shots and the maxis.
I only took the .405's up to about 80 (because I really didn't know if I wanted 90 or 100 gn behind that bullet....wasn't sure about the pressure).
Anyways... When I started shooting, I was getting a misfire about every other attempt. I picked the holes, just to check, and really started to make sure I was putting the cap on tight... Over time, I didn't get misfires. I'm thinking that when I stored the gun last, I may have pushed bore butter into the fire path from the nipple...in the future before storage, I'll block that all with a pipe cleaner.
So.... I had intended to get some Precision Rifle Keith Nose .45 HP's in a .50 sabot. Was going to try 330's. Now I'm wondering, though, if this gun will get that round stabilized and keep it flying straight without drifting right. I could try 270 and 300 gn also...but time's getting short.
I'm also going to make bigger targets. At 100 yds, my fiber sight occludes the 5" shoot-n-c's I was using.
I will also do full rod bounce tamps to check my bullet seating in case I'm not getting things tight enough.
Well, 'nuff said for now.
Good luck anyone heading into the woods soon.
