I don't know of any meals that fit strict carnivores, but there are some snacks that are pretty much just freeze dried meat. The stuff tastes terrible to me so have not had much of it. It is also quite expensive.
Pemmican would work but it is really best to make that at home. The commercial stuff I have tried has been low quality but priced like it isn't.
If you want to stay keto but are ok with some ingredients that aren't strictly carnivore, take a look at Next Mile.

These taste great to me and have the best fat/protein balance I have seen.
Look close at the back of these ingredient profiles on Next Mile Meals. Great marketing. Some fillers and the bad oils in them if you read the ingredients, soybean oil and canola oils in their meals. They advertise well and sell the "keto friendly" idea well so people jump on the bandwagon, but I assume Zap, your diet is already very clean and you've cut this stuff out anyway.
I wouldn't touch most of their stuff after reading the actual ingredients rather than buying in on the keto marketing. Couple options on their site without the bad oils if you want to go off carnivore while hunting and add back in some stuff.
What I've been doing is buying freeze dried meats, beef chunks, chicken chunks, pork. Add heavy cream powder, powdered butter, pink himalayan salt. And if you're open to it, there's single serve olive oil packets to add as well to your meals.
Breakfast, freeze dried eggs from nutristore. Mixed with cream butter and dehydrated cheeses. Hormel sells chopped up packs of real bacon, add to eggs.
Pemmican will be a test this fall to see how it turns out. I'm making some in the next week or two for the fall hunts to see how it is.
Snacks, Make your own jerky as well. Sugar free. I also love moon cheese. Great for a snack.
The only stuff I've seen is doing it on your own and making your own meals. That's actually equivalent to what you'd eat at home and keeping it clean, regardless if you want to eat keto or carnivore.
