Hello, I just bought a rifle chambered in .375 HH and have this question regarding recoil.
Would there be a decided difference in recoil in 300 grain bullets clocking roughly 2500 fps vs 270 grainers clocking roughly 2700 fps?
I am assuming the 300 grainers at 2500 fps should be a stouter recoil. Correct?
Sorry if this is a dumb question, just trying to learn.

I think there might be on paper but depends on what you percieve - I've used from 220gn to 350gn in that cartridge and don't really notice a difference but the rifle is heavy.
The heavier bullets in many cartridges are supposed to generate more recoil. I can notice it in my 458WM between the 400gn and 500gn.

Whatever you said...everyone knows you are a lying jerk. That's a bold assertion. Point out where you think I lied. Well?

JBM, online, has a recoil calculator. Simply enter the rifle weight, powder charge weight, bullet weight, and muzzle velocity.
I'd rather be a free man in my grave, than living as a puppet or a slave....

If using the same type of powder then zero difference. Some times different powders will increase recoil, especially if combustion is not right.

Energy is energy, if a load provides more energy at the muzzle it is also going to provide more at the other end
Now perceived recoil has some more variables. Stock design, velocity, etc. I can tell the difference between 150 and 165 and 180 in a 300WSM. the heavier bullets feeling like they kick more.
I would guess the OPS original assumption is correct.

Shooting 5 different 375 H&H's with barrel lengths from 20" to 24" and rifle weights from 7 3/4# to 11# with both 270 and 300 grainers in each rifle I personally did not find much difference in recoil. But that is just me. Actually I decided to stick with the 300's in each rifle, although for North America a lighter bullet (235/250) would probably be adequate for pretty much anything. Terry

I wonder how to enter powder weight when it has a break?
I prefer classic. Semper Fi I used to run with the hare. Now I'm envious of the tortoise and I do my own stunts but rarely intentionally

Trying to factor in a brake would be tricky - the angle and speed of the gas (powder) would vary between makes and models.

I've run 270s @ 2550 and 300s @ 2200. No difference from the shoulder. A machine could probably tell you Kore.

Having loaded both 270gr & 300gr Woodleigh in my 375H&H with H4350 & Win760, I can tell you the recoil impulse with H4350 is sharper even though velocity was very similar. After re-chambering this rifle to the Weatherby, this trend of the recoil impulse being sharper with H4350 has continued. A regular dental appointment is needed if using H4350.
Cheers.

Strange, they are supposedly nearly the same burn rate, though the 760 is much more temperature sensitive.
I have not noticed a difference with H414 (WW760 clone) and 4350. (I'd only using the H414 for case forming.)

Out of my .375 Wby, I have shot 260gr ABs at 2,975 fps and 300gr NPs at 2,750 fps. The rifle is fairly hefty, so neither is very uncomfortable, but I "felt" a bit more impulse from the fast 260s.

Don't feel much difference in the two with a heavy Model 70. Dropping down to 250-260 grain bullets seems noticeably less but I am not pushing them that fast at 2,850 fps. The 235 better still. The 300s hit a recoil threshold for me and the 270s might be just a bit less at 2,700 fps, push them over 2,800 and then they may have more felt recoil than the 300s at +/-2,500 fps.

My pre-64 375AI (10 lb) is a mild kicker with all I've tried in it, but so far I have not shot 300 grain bullets in it - mostly 270 grain. I have not felt anything different with different powders when pushed to the same velocity.

I have a nine pound .375 H&H, find that recoil of the 250s is only a little less noticeable than the 270s and 300s. But the 350 Woodleigh was a different cat altogether - very noticeable increase.

I only use 300 gr Shock Hammer bullets in my 375 H&H @ 2670 fps. If I wanted to use 210-250 gr bullets I'd use my 340 Weatherby, 250 gr Nosler Partitions @ 3050 fps. JM

I have shot my 375 so much I shot it's throat out and had to re-barrel it. I went through many thousands of both 270 and 300 grain bullets. I actually can't tell the difference in recoil from one to the other.
