I'm a huge fan of this pack. I've regularly used each of the weapons here (especially the Hudzik .50 Caplock) over the past few years, and each one is pretty satisfying and unique to use.
Hudzik .50 Caplock (irl: Hawken Muzzleloader)
Easily my favorite part of this weapon pack. I'm a huge fan of more classic weapons (muzzleloaders, lever action rifles and shotguns, etc.), and this caplock rifle does not disappoint.
While it definitely gets outshined by the more recent Gandhare Rifle in the hands of a good marksman, the ability to use a unique muzzleloader scope, as well as switching between two different types of ammunition offers a range of flexibility for those who want to use the Hudzik. That being said, the round balls (covers classes 3-7) does have a more noticeable range reduction compared to the minie balls (classes 4-8) with a maximum effective range of 100 meters vs 200 meters, so if I'm hunting class 3 animals, I prefer to save a different weapon for those if I need range. That being said, it can be an effective weapon with either ammunition. I particularly love to hunt moose with the minie balls, I find it much more exciting and satisfying than more recent weapons like the Arzyna .300 Mag Tactical (an AR platform chambered in .300 magnum, found in the High Caliber Weapon Pack).
Because it is a muzzleloader, it has a very lengthy reload time. This means you won't be landing any followup shots with the weapon, but this isn't an issue as long as you have good shot placement (which isn't too hard, because everything besides moose is easy to smash lung with). It has a higher effective range, but has a dramatic bullet drop compared to more modern rifles, so I highly recommend using the Zeroing perk to maintain that accuracy.
It has a solid sight picture with its iron sights, and the scope that it comes with is pretty nice as well. It comes with a more vintage German reticle by default, but with the recent Scopes and Reticles update, you can customize this to your liking.
On top of all that, it also has exceptional visual and audio design. It looks gorgeous, and the sound design really sells the vintage muzzleloader vibe. If you listen closely, you can even hear the hammer strike the cap right before ignition. It also creates a TON of smoke after firing (just like irl muzzleloaders), which can be a little tricky for keeping track of what you shot, but it's not too much of a hindrance.
Overall, the Hudzik .50 Caplock is a 10/10 for me, and I bring it wherever I go for most game, from Whitetail Deer, to Red Deer, and even bears and Moose. It's exceptionally powerful, and depending on the ammo you choose, you'll have a very flexible weapon for taking down most game. You only get one shot with it, but one shot is all you'll need. As the game's flavor text even states, "a perfect weapon for the confident hunter, as challenging as it is rewarding." It takes practice and confidence to get the hang of it, but it's hard to put down once you catch on.
M1 Iwaniec (irl: M1 Garand)
A favorite of many, the M1 Iwaniec is a very nice recreation of the infamous M1 Garand. It's chambered in 30-06, making it pretty versatile for most medium to large game. I don't have as much to say about the M1, as it is just a semi-automatic 30-06, but it is certainly a reliable and versatile rifle to bring with you. And yes, it does make the iconic "PING" sound.
While you can stick with its iron sights, various rifle scopes can still be mounted to the rifle, which is a nice touch and makes it easier to use over longer distances.
I know some have complaints that it has a reduced magazine, down to 5 rounds (from 10 irl), but I believe this is made to reflect some irl hunting regulations, as some places require modifications to civilian-owned M1 Garands to have a maximum capacity of 5 rounds. That being said, this is hardly an issue in my opinion, as being able to rapidly land follow-up shots and recover missed shots quickly provides a huge advantage.
Overall, I'd rate it as another 10/10. While I don't use it as frequently as the previously mentioned Hudzik, it is flexible, reliable, and satisfying to use.
Miller Model 1891 (irl: Winchester Model 1887/1901)
Without a doubt my favorite shotgun to use, the Model 1891 is an exceptionally powerful 10 gauge lever action shotgun. While the newer Strandberg 10SA (also found in the High Caliber Weapon Pack) is more flexible and customizable (able to use a scope to aid in hunting with slugs), that doesn't degrade this one any. Its 10 gauge slugs can bring down large game, and its 10 gauge birdshot works exceptionally well on turkeys and geese.
Aesthetically it is gorgeous. It perfectly captivates the look of a "Wild West" repeating shotgun, and the engravings on one of its variants are beautiful. However, one of the variants, with some brass or gold structuring, can be a bit jarring while shooting birds in the air.
My only problem with it is its sight picture. While it's nothing they did wrong with it, as it accurately depicts what a real Winchester lever action shotgun from the time would've had, the tiny bead sight can be tough to aim with at times, which is where the newer Strandberg 10SA comes ahead.
I rate it an 8/10. Overall very satisfying to use, but with a few things that can make using it more difficult.
Conclusion
I'd say the Smoking Barrels Weapon Pack is absolutely worth purchasing. The weapons are unique and exceptionally fun to use, and they get their respective jobs done very well. While they have some competition with other weapons, these are all still very satisfying to operate, and their uniqueness alone makes them stand out to me. As you can see, I'm very partial to the Hudzik, but I'd definitely recommend any of the weapons in this pack.
