S2H winter class 2026 observations and lessons learned

[Formidilosus]

I’ve used these mags for several months now in 223 and M+ sizes.

All 4 of them have thousands of rounds each and have performed VERY well.

They’ve done well in desert heat and blowing sand here in AZ as well as blowing dry grass/foxtail dust in VERY windy conditions in Northern California.

Good to hear.


And good to see you post.

Did the parallax essentially become immovable as well? Any diagnosis? Happen to all of them?

I had ranger bands on my parralax knobs before I got to class.

One more thing that got discussed but hasn't been posted about in this thread is gun lube. I have used various lubes over the years with mixed success, but as was brought up in discussions there are lots of negative side effects of common lubes (toxicity, off-gassing at temp, etc...). After hearing of TW25b, I will be giving it a go on a few guns to see how it does. My backup plan is to raid the pantry and de-virginize some olive oil per @Formidilosus recommendation.

What do y'all mean by "clocking" the scope bumpers - I have a couple sets in my cart ready to purchase as soon as HouseHold-6 signs off on the expenditure.
Thanks

Here's a picture, just rotate them to make opening a fluid, one-finger affair. On the ocular, make sure it clears your thumb when crab-clawing the bolt/clears the bolt itself on the underside. This will be scope & ring-height dependent.

@Formidilosus on average what percentage of students come with rifles properly assembled and zeroed?

What have been the Most common mistakes? Aside from aftermarket trigger springs

For the Atlantic Rancher - Ranger sweater users, is there a consensus on the preferred style (solid vs 1/4 zip vs cardigan)? Any general feedback on style merits or drawbacks is appreciated

Interested to hear this reply. I think it really depends on how tuned in they are. Before I started reading around here and objectively testing things myself I would have never done half of the things I do now as standard practice. The techniques that work are not common in typical shooting/hunting circles and you wont find them condensed in one place. I was happy that mine showed no issues that were the fault of anything in my control that werent inherent to the platform. Everyone was not that lucky though.

I thought ths cool part was that anytime something did go wrong, it was used as a teaching moment for everyone who wanted to observe and learn the what, why, and how.

Could I get the name of those lens covers? Those look darn useful.

I could be wrong - but I’m fairly certain these are the scope caps @Formidilosus has on a few rifles

In a pre-order status currently.

I have no affiliation I’m just a guy who has not found the “Goldilocks” scope caps yet.

This was my point on using your hunting mags instead of 10 rounders.
I understand you do mag changes but for how you train why not use the 3/4 rounders and get that many more mag changes in practice.
Just curious and you can buy 4 or more of these for the price of 1 of the others.

Compared to others, the Maven on my 6mm does not have issues. I put it outside last night (~15*) and checked it this morning, mag ring and parallax are both still usable. On the other hand, the 3-9x SWFA on my .223 will give you a forearm workout trying to spin the mag ring in almost any temperature, even above 40*. No ranger bands or throw levers on either scope.

For sure. I started taking my oldest with me when he was 4.

Oh, mine do outdoor stuff with me a lot. Possibly even an excessive amount. I just don't think they'd handle the winter class well. Or the rewarming drill. lol.

I wonder if this is a design feature that applies to every scope of that model or if it's variable between scopes? I ask because I have some older scopes where I had multiples of the same line/model and you'd get one that was really tight then another that was really loose and otherwise they seemed to function the same.

I wonder if there's a 'damping grease' they use in that assembly that maybe varies from lot to lot?
