Recoil comparison

[Dooder]

Hey guys, so I just got a 300win and am thinking about the many possibilities of loads and came up with a question regarding reduced loads. It may seem amateur however I do get mixed responses when asking people so I thought I'd try it here. I haven't loaded 300win yet so I don't know how it will behave with reduced loads.

The question is very simple and theorerical right now. The weights aren't concrete just using them for comparison.

Take a 308win load - 168gr @ 2800fps. That's a pretty good thumper right there. Now thats on the high end of 308win loading.

However thats a starting load for 300win. Does this mean that the 300win will thump less at all? Or will it feel the same?

If you are reloading to hunt then plinking rounds may recoil less but won't help you when you load up a hunting round because you will expect more recoil/PAIN and that may effect your accuracy.

Has nothing to do with hunting. I didn't even mention hunting or any intent for the hypothetical load given as an example.

I'm just asking about about a comparison of how the same load, (same projo weight and velocity) will behave in two different cartridges.

Recoil is generated by the mass and velocity of the ejecta from the barrel.

The 300 WM has a bigger case so it will require a little bit more powder to generate the same pressure behind the bullet to reach 2,800 fps. Theoretically this means that the recoil will be slightly more than the identical bullet at the identical velocity from the 308 Win, if the weights of both rifles were identical.

Since the 300 WM has a longer action and usually a longer barrel (in sporter weight guns) the felt recoil in the magnum rifle will probably be less than from a lighter 308 sized rifle.

This was my thoughts exactly. Thanks for the reply. I think it should feel same or a bit softer. My friends say no, I guess Im seeking some validation haaha. Thanks! Anymore thoughts?

I have no idea if this article will help you but pretty interesting.

1st get a shooting vest [ padded ]. Mount a scope — that little extra weight will cut down on felt recoil .
If you are just going to punch paper , the only reason for the magnum is the WOW factor .
You can also get one of the bullet holders that slide over the butt of gun .
My nephew said the by-pod cut down quite a bit on recoil . Weather he was justifying buy it or not does not matter .

Be careful with reduced loads in the 300 Mag. Don't go below the starting loads with the slow powders. If you do, you can get hang fires especially with Ball powders, they also don't like to be downloaded below starting loads.

If you want some loads that would be similar to the 30/06 or 308 win velocities, you can use a powder like IMR or Hodgdon 4895.

I found this out some years ago with the 300 Win. Mag.

Yea that imr4895 is awesome stuff. I understand reduced loads but please remember this is all theoretical.

Thanks for the replies. However my concern is not hunting or plinking, or mitigating recoil or dealing with recoil or anything having to do with actually shooting the cartridges.

Here's the question worded differently:
If a certain load, any load, in 308win is ballistically duplicated in 300win, will the 300win rifle feel softer when fired?

Here's an example- 45acp 200gr @ 865fps feels softer than a 40sw - 200gr @ 865fps.

So how will a 300win shooting a 168gr @ 2800fps feel compared to a 308win with the same 168gr @ 2800fps load? The same? Recoil more or less?

If the guns weight the same , maybe .
Things like a plastic stock , one weighting more , a longer barrel - nd many more things add up to felt recoil .

Properly shouldered you shouldn't have issues with recoil.

If you can match the .308's fps in the 300 case using the same amount powder and if everything else exactly the same ... The recoil would be the same. I'm thinking you'll be using atleast a few extra grs ( 5 ish) in the big case to match the smaller/ more efficient .308 case. I use these calculators http://www.handloads.com/ when I ponder such things.

Hodgdon let's you make H-4859 reduced loads...

Same bullet weight & same velocity = same foot pound of energy...

A fast powder will have a shorter / sharper recoil impulse / acceleration

Basically an bullet and velocity combo are the same energy

Momentum = mass x velocity
ke= 1/2 mass x velocity squared


Mass and velocity are the same.....


So text book is the same recoil



Recoil is mitigated by the weight and dimension of the gun
Muzzle flip is mitigated by a variety of factors including barrel length
