recoil question?

[Droopy]

How does bullet weight effect recoil? I always have shot a 180gr. thru my 30.06 but dropped this year to 150gr. Is there a general rule of thumb regarding bullet weight and recoil change?

 

[cdw338]

General rule. The lighter the bullet the less recoil.

 

[Droopy]

My gun does seem to kick alittle less, but seems to have more muzzle jump on my rest, does this sound right?

 

[Whelen Man]

General rule. The lighter the bullet the less recoil.

That's exactly right like he said as a general rule. However, there are hot 150 gr. loads and light 180 gr. loads. Sometimes they can seem to be reversed according to the powder and load but what cdw said is a good general rule.

RECOIL ENERGY is just one part of 'felt recoil'... drop bullet weight and recoil energy does decrease, but MV probably increases as well... that increases your RECOIL VELOCITY. In other words, the gun won't come back at you with as much force, but the speed at which the gun comes back at you actually increases. So you may feel a sharp pop compared to a hard slower push.

My cousin swears 250 grainers out of his 338 EDGE are almost unbearable due to the velocity of the recoil, while 300 grainers are a piece of cake.

Same situation with 44 mags... I can load slow 300 grainers and the gun rolls in my hand and is quite comfortable to shoot, but take 250 grainers at a higher velocity and your hand is stinging from the sharpness of the recoil.

along with speed
u can calculate felt recoil

by taking powder weight bullet weight rifle weight and speed

using point blank ballistic program it will give u
recoil engery and recoil velocity

ie

my 270 with a 140 gn load 19 ftlb recoil
pmc 375 h&H 300 gn load 37 ft lbs
300 rum 208 amax load 57.9 ft lbs

Almost 58 ft/lbs with the RUM. WOW! How many grains of powder are you burning with that load? I can only imagine what that feels like.
I'll stick to a plane jane 308 loaded with 165 grain bullets and 46 grains of powder.

Thats crazy. I have been in so many "heated" arguments with deer hunters braging on the killing power of their 7mm mags and 300mags. I feel like every rifle caliber has its place. That being said, I see no place in whitetail hunting for either this side of the Pacific.
I'am sure a 300 or 7mag are great for putting the bull Moose on his arse(but which my cousin dropped his in his tracks with a .308) but not whitetail. I killed a 160lb buck Thanksgiving morning with a 30-06 and 150gr. federal with a single shot to the neck @ 80 yards. The damage was EXTENSIVE. I should have took a pic. I Could not imagine needing anything more, and I;am honestly considering using my .243 the rest of the season.
IMO its a [censored] swinging contest. But to each his own.

I deer hunt with three calibers 223rem,7x57 and 300RUM. Each caliber has its place, I shoot the 300RUM for its flat trajectory, not to impress my friends, I take pride in making precise shots and the 300RUM makes the calculation of bullet drop a little easier at longer ranges. Shooting a 300RUM does not always indicate a lack of shooting skill, most people that I have came across that shoot the big guns usually put alot of time and effort into shooting the guns effectivly and not to mention the time spent on tuning reloads to your specific guns. But each to his own.

PS: I shoot 100grs of Retumbo in my 300RUM reloads with a 180gr bullet.

 

[cdw338]

If you are getting to much damage, you are using the wrong bullet. Go back to the 180 grn bullet.

I myself think the 243 is light for deer. Many others don't.

With the right bullet the 7 mag or 300 mag will not cause excessive damage. Im of the old school, use enough gun.

 

[cdw338]

In my 300 Ultra mag, off hand I think I was loading 85 grs, or some place around there of IMR 7828 with a 200 NP.

Recoil was not bad, no sharp rap, more of a push. Same for my
338 no rap just pushes.

Your lack of knowledge is showing in this post...

I'm sorry you have it in for the ultramags, especially since the 300 RUM will perform at 400 yards as your '06 does at the muzzle. And a third the bullet drop and wind drift as well. As long as you keep hunting under 100 yards, I would make the argument that your '06 is redundant. Heck, under 100 yards, a good ole 30-30 will do just as well.

Sure, the overbored magnums have a place in Eastern hunting. In fact, my crew has already taken 3 deer this year alone over 525 yards away.

 

[Droopy]

I was not comparing a 300 and 30.06 by any means. I just don't see the need for the extra "kill".
Like i said, to each his own.

that all depends on the cartridge. recoil increases as a square of the velocity and bullet weight. there are cartridges where the recoil velocity is greater with a lighter bullet. 7mm rem mag is a good example. 150 gr recoil velocity is 14.0 fps, and the 175gr is 13.7 fps but the recoil energy increase is only .75 ft-lbs for the lighter bullet.

that said, for standard cartridges like the 06, as a general rule increase in bullet weight also increases recoil energy.

as for felt recoil, a lot depends on the shape of the stock, length of pull, shape of butt, recoil pad, forend shape, etc. can reduce felt kick.

That was my point exactly in the previous quote...

Anyhoos, you can't simply take recoil energy in ft-lbs and make an absolute translation into 'felt recoil' If that were the case, my cousin's 416-06 JDJ with 400 grainers at 2000 fps (in a pistol, no less!!!) would remove your hand after the hammer drops. It generates well over 50 ft-lbs in the pistol configuration.

geez, your cousin must like punishment.lol. pistols are even more harsh cause you have spin torque as well.
