I need to purchase a more powerful hunting rifle, but I am worried about the recoil. Would the recoil of a magnum rifle be similar to a 12 gauge shotgun with magnum shells?
Historically, the most powerful hunting weapon is rifle. They have a large caliber and long rifled barrels. As a result, a heavy charge acquires a high initial velocity with a very large energy reserve. But I advise you to take into account the article about Red dot sight here. Red dot sights make you a fast shooter; this is if you have excellent shooting skills
I am hunting for many years, and, from my experience, I can say that I think that it’s not going to work. However, you need to find a guy that really knows a lot about guns and ask him, it all depends on many factors. I didn’t know which gun to buy, so I found an expert that knows everything. I bought that certain gun that he advised me to buy, and carry it in my hunting daypack now. He helped me a lot, I didn’t know a lot of things.
I recommend you to try AR-15 it is the most popular rifle. It is a semi-automatic version of the United States military M16 rifle that is marketed to civilian and law-enforcement customers. Also I can say that you need to choose good modern scope, for example there are great smart optics from ATN https://www.atncorp.com/smart-hd-optics it will be great choice.
Take a look at the “Expanded Shotgun Recoil Table” and compare it to the rifle cartridge you are considering in the “Expanded Rifle Recoil Table.” Both can be found on the Tables, Charts and Lists Page. But be advised that, subjectively, shotgun recoil bothers most shooters much less than equivalent rifle recoil because shotguns are usually fired from a dynamic standing position while the shooter concentrates on the target. Rifles are fired from a static position, and the shooter’s attention is on the sights. Try shooting your shotgun from a bench rest at a rifle target, slowly squeezing the trigger for best accuracy as you would a rifle, and see how it feels.
