    I recently bought a Remington 700 SPS 300 RUM without a muzzle brake I know I want a muzzle brake but do lighter bullets have lighter recoil? The ones I’m shooting now are hornady 220 grain eldx and the recoil is unreal

    Yes they do. I have the same rifle. I would put a brake on if I was you. If I shot mine anymore it would have a brake. That’s cause I’m getting old. Lol

    The lighter bullets might have a slightly reduced recoil but it will also likely be a bit snappier. You may or may not find it more pleasant.

    300 RUM is just a brutal cartridge. Definitely put a brake on it and if you can wing it a suppressor will help allot to in both recoil and muzzle blast. Adding weight to the rifle in general will help too.

    I hunt with my .300RUM, so I mostly use 180gr bullets.
    A recommended starting load with IMR7828, or H4831 will significantly reduce recoil.
    Performance will still equal a .300WinMag with factory ammo.
    ( 180gr bullet @3,000fps).

    You can save $$$ by shooting bulk surplus powders.
    Jeff Bartlett at gi-brass.com has plenty! I’ve been working on 16lbs of WC860 since 2005. It was $4/lb iirc in 8lb jugs.

    Difference in recoil between heavier and lighter bullets, is the "peak" and "length" of the amount of felt recoil.

    Lighter bullets are moving faster and have a higher "peak", but he length of time of felt recoil is less.

    Another factor, powder. Heavier bullets, generally, use slower burning powder. The burn time, therefore is slightly slower, and allows for more felt recoil.

    Bulk surplus powder, where would one get that these days, or did that also come from 2005?

    A brake will certainly tame the recoil, but keep in mind how much powder the round is burning; it will be extremely loud.

    A suppressor would be my recommendation. 30-35% recoil reduction in addition to the sound and blast/concussion reduction.

    My 300 Wby sucks to shoot at the bench, I imagine a RUM would be just a bit worse. A brake would help but mind your ears.

    That’s what I’m trying to figure out in a hunting situation as far as hearing protection and still being able to hear something coming

    It's a Catch 22 situation. None of my rifles are ported. At the range I use hearing protection for all my rifles including my .338 Win Mag, but I do not use it in the field. As Kwaynem states you have to be able to hear (and see) what is coming. For myself, I would not use any ported rifle anywhere without hearing protection.

    I have been buying bulk powders from americanreloading.com. When they have powder available and they put it on sale it’s a decent buy. I picked up some 8 pound jugs last year for about 150 bucks each. That includes free shipping and hazmat.

    Gi-brass has both 7383 and Wc872. Either will work in the .300Rum.
    In stock! Or I wouldn’t have suggested.
    IMR7383 $70/7Ib . Does NOT include shipping or hazmat.
    WC872. $60/8lb

    The 7383 will use H4831 data, reduced 15% for starting loads.
    WC872 will use H870 data. (Start at 98.0gr, max at 108.0gr).
    (Lee #2 manual has data).
    Again, check out the web site yourself.

    That's what suppressors are for!

    I built a 1.8x10 incher for my .375 RUM, but they don't need to be quite that big, I just wanted it really quiet. That .375 in the 7.5 lb 700 BDL SS was downright brutal, pushing 300 gr. spitzers at 2,970 FPS, gave me a headache after a half dozen rounds. The can took the recoil down to about the level of unsuppressed .338 win mag, and it's perfectly tolerable for my sensitive ears shooting outdoors. For my sister's .300 RUM, she uses my 1.6x8" Accipiter model, so it has a little more bark than you'd want to tolerate for dozens of rounds on the range without ear pro, but quite tolerable in hunting situations of one or two shots.

    Eform 4 went live last month, and the projected wait times are <90 days now, so it shouldn't be as much of an encumbrance as it was with 10+ month paper for 4.

    A can built to handle your RUM will also take pretty much anything else .30 cal & under. Once you shoot suppressed, you won't want to go back.

    This is the .375. Yeah, it's a big can

    This is my 673 guide gun in .350 mag with the smaller 1.6x9 Accipiter. 4" less barrel and 1" shorter can makes it a bit more manageable. At close range, the bullet impact is often the loudest noise.

    That’s something I want but need something sooner than 6 months or so

    Well, you'll need your barrel threaded either way (unless you were thinking about just porting it, which is probably more expensive), so do a little research on cans and mounting systems, choose one that either has a muzzle device interface with brake options you like, or go for one that uses industry standard 1.375-24 Bravo pattern mounting and you can choose from a long list of mounting system adapters with different muzzle devices. Then you have your brake, and you'll be all set to put a can over it when the time comes!

    Griffin Armament has about the widest selection of muzzle devices, and there are several adapter options to use them with multiple suppressors:

    https://www.griffinarmament.com/accessories/muzzle-devices/

    YHM makes a good QD mount brake that also has a 1.375-24 adapter option

    https://yhm.net/sound-suppression/accessories-mounts/qd-brake.html

    There is also Cherry Bomb pattern, for which Rearden and Liberty Precision make brakes and Rearden makes Bravo adapters:
    https://www.reardenmfg.com/product-category/muzzle-devices/muzzle-brakes/

    https://www.libertyprecisionmachine.com/collections/muzzle-brakes

    Rugged has some good brakes, and while they don't offer adapters, I did start making Bravo adapters for those late last year

    https://ruggedsuppressors.com/rifle-suppressor-accessories/

    Dead Air offers a Keymo brake, but I'm not a huge fan of that system, too many QA problems with KGM (who makes the parts), and a few instances of on or more of the 3 little retention tabs breaking. It's also heavy and expensive.

    Our Gyrex brakes are awesome inside a suppressor, but they weren't designed as open air brakes and therefor are not the best choice for that.


    There is another important consideration, and that is that your .300 RUM, if a sporter, probably has a ~.65" muzzle diameter, which can't support 5/8-24 threads and have enough of a shoulder without adding a collar. Unfortunately, there aren't a whole lot of brake options in 9/16-24 and the RUM is a bit hot on exit pressure for 1/2-28, so either threading 5/8 with a collar or going 9/16 and using a 9/16-24 to 5/8-24 adapter will be the route you'll need to go.

    I hunt with a .450 bushmaster with a brake, which is a complete toy compared to your .300RUM. I absolutely will never shoot it again (I was dumb enough to try once) without hearing protection.
    I have a set of walker razor electronic earmuffs. The sound quality is good enough for hunting, they are comfortable to wear, and they have enough noise reduction for a couple shots hunting. I stick with plugs or heavier muffs (or both) when at the range.

    I've got a set of those electronic ear muffs and they are very nice to have.

    I've also got a suppressor in jail currently on a E-filed form 4.

    I definitely have some hearing loss, and I intend to keep what I've got left.
