So everyone has mentioned that fundamentally, you can control recoil. While I agree, I am also a realist.
Let me put this on the table as a guess.. I sounds like you bought yourself a hunting weight 300wm with the typical pencil barrel and added a Boyds or similar stock that might have added a pound or so, a Harris or clone type bipod and you're trying to make it a target or dual purpose rifle.
If that is the case: You're probably going to be fighting your equipment more than it is worth and in the end, the equipment might just do more damage to your learning than good. These factory weight hunting barrels in the bigger magnums tend to walk as you target shoot, get extremely hot very fast and cause barrel mirage. This makes precision shooting rather tough. On top of that, while your trying to develop the fundamentals people are talking about your getting beat by the non-braked, light 300WM most-likely on a rather rough bipod.
If this is even remotely the cause, you just walked into the Finch University.. You might not be a graduate yet. But if you try to target shoot that thing too much, with too many rounds in a row, I bet you'll graduate with a Masters Degree in Filching and poor trigger control.
Yes, I can see my impacts with my magnum with a base weight of <6lbs (before the scope, rounds, bipod etc). But damn, it hits hard, not fun to shoot and if I shot it all day, all the time, I'd start to flinch too.
Here is a post I just did yesterday on this very topic for a youngster wanting to get a 7mag in a hunting weight because he "is not recoil sensitive". It explains a bit of what happened to me as a young shooter trying to use a hunting magnum for targets and sustained rounds.
Many target shooters, many of my friends and fellow competitors, have never really tried to use a light weight, non-braked magnum with a cheap bipoid, as a target rifle. The above my not even seem like a big deal to some who have not shot these rifles for extended periods, but it is a very real handicap. There is a world of difference between a 300 in a 9lbs system on a crap bipod and a 16lbs+ plus rifle with braked/can set-up as a target rifle..
In an non-braked 300 with 180s a bit over 3050FPS your dealing with a recoil impulse over 31LBS recoil energy. A 20lbs rifle with a brake, is going to have a
much slower recoil impulse, and maybe <7lbs of recoil force - Thats truly huge at almost 80% less felt recoil and far less "snappy". Plus, the barrel and bipod are going to aid in precision. A 6.5 RPR or the like, in the long run, might be a cheaper all around 1000 yard target solution than trying to make a 300WM hunter into a target gun.
If my guess is off base, sorry. The only intent is to raise awareness to the pitfalls that so many of us have struggle through.
