SL68 and StarMetal Orange at -7°F
Well it was warmer than I thought as a thin overcast came in. I started at -7°F below and finished at -5° a couple hours later.
I used a Remington Model 700 Classic in .250-3000. I have modified the 'throat' .095" deeper for cast. I used a load with a 84gr gascheck .25-20 boolit. In sane temps it will group 3/4" or better at my 85 yard target. MV is 2100fps and twist is 1 in 10" .... RPM is 151,200... Sorry, I regress...
Before I get any slack for 4 shot groups let me tell you something. These 4 shots spaced 15 minutes apart will tell you more about performance in bitter cold that 100-10 shot groups in weather the rest of you shoot in!!:kidding:
Point of impact is where it was at 80° warmer. Barrel visually looked good all 8 rounds. The very first shot (cold start) was dead-on both lubes! I am fighting a C.O.R.E. issue for the dropping shots; not sure what it is... It could be time! The last shot was 45 minutes spacing (StarMetal) and it was back into the group! I had some chores and had to stoke the stove so it wasn't planned.
I consider this passing grades for both at these temps; especially for hunting with the first shot perfect. I know what minus temps can do to a lube! The two lubes acted a lot alike in this test. All loads sounded sharp. The ammo sat out all night! Gun 3 hours.
This is a brutal test for a boolit lube. I think it harder to pass that Gear's 'dashboard Texas summer test!
Targets are attached with shot sequence numbered. A close-up of holes is attached especially for Lamar. He likes to look at my 'holes' close up! [smilie=1:
Last but not least is the Model 700 finally back in the warm house!
