S2H Winter Rifle Course Observations/lessons

[Formidilosus]

@Formidilosus, I haven't read through the whole thread so apologies if you already talked about this.

I saw where the MRC rifle failed and was cleaned/repaired and then worked. Since this is advertised as completely field ready out of the box, is this a failure to meet that goal? Is MRC going to do something differently going forward?

No, that’s not a failure. People won’t accept a rifle that is bone dry out of the box- they’re going to have to be lubed. Lube failing in extreme temps isn’t a rifle thing- it will happen to all.

Makes sense. Do you know if they will switch the lube product they are using to one that works better in extremely cold weather?

I do understand that less than 1% of hunters will actually be hunting in conditions this would even become an issue.

 

[Formidilosus]

Makes sense.

Also, I didn’t put it down as it didn’t occur to me really (I was highlighting anything that happened to the MRC) but everyone degreased their bolts the second day, there were a couple that had light strikes- all due lube on the firing pin.

I’m going to talk with them about it when I go to MRC. They can switch to one that is better for cold weather, but in truly cold weather none of the common ones work- you have to go without lube, or use lubes that aren’t great in normal temps.
The rifles are coming with cards or a paper that has QR codes that will take you to an explanation of each item- one of them will be about setup for extremely low temperatures.

Have you or anyone else ever tried dry graphite for lube, such as imperial that is used for case necks/bullet seating?

Of course it does nothing for corrosion prevention but may slick up surfaces inside the bolt. Maybe it's not needed, but just a thought I had.

Would it be worth it to get my bolt/bolt parts DLC coated to reduce the need for lube or is that spending a lot of time fighting an unneeded fight

Graphite yes. Not imperial.

For most use/conditions it’s not needed.

Melonite, etc. is better. But, it’s really not needed.

Relating to cold weather and lube, Did you run the mk12 at the winter course? Does it still have grease and if so does it ever not cycle or do you change lube in below zero conditions?

I did, I purposely left it greased with no adjustment from summer use- it did not cycle at all-15° F.






I wiped off the grease, and applied 0w30 motor oil- it worked fine after that.

How does the Duckworth Powder hoody compare to the Atlantic Rancher Ranger in terms of warmth and dry time?

I'm curious what lubes you would recommend... obviously there's tons out there and I just was curious if you had a go to. I've always used G96 as its supposedly rated to like -75 and I haven't seen any issues, but I haven't tested in conditions as extreme as this course.
