.300WM or 6.5 Grendel

... which is better out pass the 1400 yard mark???
I've seen some post on another forum 2000 yards with a .300WM and I guess the round starts tumbling getting out there... I wonder if the 6.5 Grendel is capable and or better...?

I love my .308. Shooting it is good for out to and inside 800 yards consistently... out to a thousand is fun... out between the 1200 and 1400 yards I begin to put expensive holes on the ground more than anything... and the mile shot (especially up in Pawnee... well it's the only place I could try such a thing) still eludes me [hahhah-no]


With all of your superior knowledge in Long Range shooting. Knowing both rounds are pretty capable of reaching out there, but which one will hit that mile mark consistently and beyond?


I would get a .338LM, but that would require me to buy myself another 6 month wait on a can, and then some.....

crazy... yep, I know... but what do you guys think?

Yup.

F**k it. Just go .50 BMG. [Awesom]

[LOL]

.300WM or 6.5 Grendel?

This one is an interesting round. I had to look this one up.... barrel life at 600 rounds, wow... that's some hot sh*t!

"barrel life lasting around 600 hundred rounds before it needs to be replaced"

Grendel is way over rated and is the worst choice that can be made for a long range 6.5 . 300WM runs circles around the Grendel which is realistically no better than an 800ish yard cartridge . Past 1K is 338 land .

Dammit... .338 land... this is gonna get really expensive, shit [facepalm]

You can't compare the .300 Win Mag and the 6.5 Grendel. They are far different cartridges for far different purposes. There is no way the 6.5 Grendel can compete with the .300 Win Mag ... and it isn't supposed to. The 6.5 Grendel is a cartridge made to fit a specific platform, while the .300 Win Mag is a long action cartridge that has the capacity for far more powder.

Why not one of the good 6.5's like the .260 or the 6.5 Creedmoor? You'll get 300WM (ish) ballistics with way cheaper components and recoil. Not to mention significantly better barrel life.

Order your 6.5 barrel from Bartlein Barrel today, it'll take six months to get directly from them. By then you can have all your .308 stuff shot up. Take your new barrel to Fritz at TJ's and have him re-barrel your gun. Done!

Not to mention, you'll have a rifle that stomps the .308.

If you want to wait a little while Berger is working on a 7mm 195g bullet with a g1 of .804 and g7 of .406. Litz designed it and it will be a beast after 1000.

The noise going on about the 195 7mm is it may be impossible to manufacture , it only lives in concept right now . If their 338 bullets are any example it took about 5 years before they went from concept to reality and the BC is way lower than they originally stated .

aw man... you guys are awesome! [Beer]

you guys sure know how to drive a man crazy with all this fantastic info!

I know they maybtake a while to get that 7mm done and those BC numbers seem pretty amazing even if they get close. But the 180's now are pretty good and at 3000fps or a little better they will get out 1400-1500 yards...and not cost fortune to shoot.

Know 2 guy's that had 7RM barrels cut for their AI's with a chamber cut specifically for the Berger 180's and one more with a WSM . The RM's could never get the consistency needed at distance and the WSM worked as desired . The VLD's in general and Bergers specifically are too finicky for my tastes . When I get around to building a 7 it will be around the 175 SMK , you give up a little in BC but gain a huge amount of forgiveness . A 7 is a real good choice for a long range gun but you trade that off in barrel life , usually less than 2k rounds , especially pushing it hard at 3000 fps .

Does any caliber that will shoot good at 1000 or better get any really good barrel life? I would think 2000 is reasonable. I wouldn't shoot my 7mag at the prairie dog match again, its too much for that. My .243 will do just fine for that and out to 1000. I have the 7mag and a 300wm that are good for 1000 and a little further but I haven't had a place to shoot more than a 1000. My 7mag shoots the 180's at 2930 and groups about .625 so I haven't really messed around with the load much. I don't think it was really pushing the load heat yet. It actually liked the 162 Amaxes and 168 Bergers a hair better and got them at 3010.

260 and 6.5 creedmore both go 4-5k on a barrel . My 260AI went 3k and was still 1/2 MOA when it came off .

The problem past 1k isn't getting the bullet there , my 260 is super sonic past 1500 depending on enviormentals, its target sign . The lighter bullets just don't make a very visible impact most of the time .

with the 300wm mag you have relatively cheap factory ammo
almost painless reloading component cost (relatively)
standard size press equipment
regular old .308 projectiles

I would go .300 WM over a Grendel. Are you sure you didn't mean 6.5 Creedmore. Like others stated, its a popular cartridge for a reason. Now that they are making high BC bullets 208- 230 gr it should make it out to a mile in the right conditions. I personally like the 208 amax, but some are having really good luck with the new Berger 215 gr Hybrids, to pricey for me. Plus if you ever want to sell its a popular cartridge. +1 .300 wm

I was thinking the same.. I'm already getting used to reloading .308 and having a great time.

Grendel... I was reading an article about it. They were hyping up the round (which i don't doubt is a good one) maybe a little bit.
Hoping everything gets back to normal some day. I will look into either .300wm and the .338lm

I like shooting far [Coffee]

I reload 223/308/300wm...thats my platform(s)
for me (at least for now) i can get it all done with those calibers on a single redding T-7 turret press with room for a powder funnel
I can p dog, slay all north american big game, shoot steel to 1,000 yds
308 projectiles range from 110gr to 220gr and come in a zillion different flavors
and there is some overlap potential for some powders too (RL-10x/RL-15/RL-19/RL-22)
with an eye on cost per round. and compnent availability and ammo (at walmart if need be...usually)
of course you can always do better, go further, and faster..flatter
the 6.5-284 is a freaking sexy ass round...man I love spotting for a friend who shoots that...absolutely wicked wicked round...but its not for me
have fun!

I'm currently working on a deal to have a 6.5-284 built. I'm really excited about how this new creation will perform out past 1k yards. The biggest challenge I see in my future will be learning the proper techniques to show its performance out at those distances! :)

6.5-284... I have heard of this round, but never had the privilege to see it in action... very interesting stuff [Beer]

They smoke a barrel in about 1,000 rounds.

well then.... I will not look into this any much further [Coffee]

I'm no expert, but I've been told by the builder that barrel life is subject to the loads used and barrel quality. The builder I'm working with uses Krieger Barrels exclusively, and has had exceptional luck. If kept between 2900-3000 fps, barrel life should be around 2000 rds, maybe even slightly better. This is assuming you're not heating up the barrel with several consecutive shots. I'm only shooting for my own entertainment, so excessive barrel heat is not something I'm overly concerned with.

Barrel life is something that I'm debating with. All this being said, previously I owned & shot the .300wm and had alot of fun. I have had the pleasure of shooting (not owning) the .338 LM which is an incredible (and proven) long-range round, but it was wicked..... good & bad! :)

Knowing me I'd probably burn through 2K rounds in 2 or 3 months... I heard barrel wait times are just as crazy too...

What's the life span of a .338lm?

I just picked up a 300WSM. Its a compromise rifle to be sure, but I like it already. Debated the 338LM, 300WM, 6.5/284, and a few others. For me what ended up making the difference is cost per round. Recoil was a consideration, but with brakes/cans/stocks almost any round can be tamed. Barrel life was a consideration for sure, but thats just part of it. I think asking what is the best round for X distance is like asking if blondes, redheads, or brunettes are better in the sack, its all subjective and dependent on a lot of variables.
Mike your welcome to shoot the gun sometime and see how you like it.

Solid Brother! I will be keeping this in mind... and you will be getting a call here tomorrow [Beer]
