Got out today cold and started snowing late. Had 2 typical and a bit better and one problem child the good kids first.
760 1.75x4.5 bushy elite 180 coreloc factory 4shots as that is the mag capacity
For some reason I will never know my wonderful wife decided that the red cleaning rod on my bench would be great to hang her delicates off. I got to the range on the way to Mom's and couldn't patch out my bores today. I shot them wet but I think I better start dong that lol Didn't measure it it's 4 shots the cold bore is high left
Second is my 308 Cold bore was high right then I shot the 9 left into the group. It was 7 degrees and I would normally have had a charge .3 higher but I left that box on the bench and took the box with the 50 empty cases instead.
Lapua 2x fired CCI 200's 43.3 Rl 15 168 smk 2.820 2640 @ 40 degrees is .3 lower this should be 2600ish~ with 43.6 in that 2640ish in this kind of temp in my rifle. Too cold to fool around with the MS.
Lastly is my 270 Today I took it out and left it on the other bench while I shot the other two here and out to 700 and 400 with the pump gun. My 308 was on my dope out to 650 then I had to add a .1 elevation to center up the steel.
2 weeks ago I decided to let this guy coat my rifle. Well I had talley scope mounts (aluminum) on the gun. The idot used a chemical that ruined the mounts. Since it was me that did this I had no recourse but to put the burris signature rings back on the gun. I would rarely have issues with them. But in certain conditions you must be aware of this issue. I fixed it after thinking about it but can anyone guess what happened???
First group is from before I coated this rifle and is common for it
Stock 270win Weatherby vangard with a Timney set at 22oz. Very nice break on the trigger. MDT LSS XL II Odin gunworks stock with mdt folder and XLR cheek peice. V Tac sling atlas 10 I think. Bag rider is not installed forgot it at home. HST 4x16
Hornady brass 2x fired 61.5 Rl26 9.5m 130sst 3139fps 3.320(long coal)

Let's put the COLD in cold bore challenge.

2 degrees Fahrenheit air temp. NW wind 22mph, wind chill -25. Nice day to go coyote hunting!

Had my Ruger American Predator 6.5 along & hadn't shot it in a while. Swung by the range when done hunting to blow the cobwebs out. Rifle was unfired (saw tracks but no yoties).

For the $$ this gun shoots. Only thing I have done is used Rockite to firm up the Tupperware stock in the forend.

5 shot group with a stiff breeze and heavy gloves. I was just trying to hold still enough to keep the bullseye in one place with the wind.

3 shots .48 inch, 5 shot total 1.14. Not horrible on a "brisk" winter day...

500 paper plates are 3.99 in the winter around here so I pick up to at a time. They are nice in the fact they don't tear up like normal targets and 9" makes a great pistol target to get a sense of what a student is doing right/wrong

First time shooting this rifle today, these were rounds 19-23 out of the new barrel from my 9 lb .338 Norma mag. Had some heavy mirage coming out of the building, it was 18 outside and about 60 inside the shoot house from a wood stove!! I think this one is gonna be a good shooter, this is the first batch of ammo I loaded up in new brass for this gun, and just a basic max pressure workup. With some actual load developement this should qualify for the .2's-.3's!!

Wanted to shoot my new Sauer 100 today at 200 Yards. I know the OP wanted to see 100 Yard groups from a cold barrel but it was plenty cold today (below freezing) so this surely can't be too far from what he wanted to see. I didn't measure the groups, but the dime is there, so think what ya want.



On the following target, pretty sure that 5th shot that strayed from the flock is not due to the rifle, the ammo, or a hot barrel, but completely to a sudden spasm of poor marksmanship on my part.

Don't have micrometer or caliper, but maybe some of the experts here can measure a dime and tell me what that 4-shot group is in MOA. Cartridge is 6.5 Creedmoor. Will be interesting to see if I can repeat it next time out at the range.
