300 Ham'r vs 6.5 Grendel. No Comparison. 

Finally, conclusive proof that 0.308 diameter bullets make slightly larger holes in paper than 0.264 diameter bullets.

Hey Dave, you and I have traveled the same road, I’m just somewhat ahead of you! I built my 1st AR with a 24” 6.5 Grendel. I found that I couldn’t duplicate the performance of the factory loaded 123 SST load. Extremely accurate and on paper ballistically formidably. I was so disappointed on its performance on deer in the field I moved away from it because for almost the same weight I could have a 6.5 Creedmoor and gain significant performance. I had been used to hunting with both the 25-06 and 308. I was looking for that level of performance. I built an AR-10 with a stupid expensive carbon fiber barrel. The 6.5 CM was one of the most accurate guns I’ve ever owned and building a AR-10 was not an experience I would recommend. That said I got it done, running like a sewing machine and took it out in the field. It ain’t no 308 or 25-06!!!! But because I had so much time and effort in it I kept giving it more chances. Ultimately it never delivered what I was looking for. I was fortunate to get my money out of it and turned to the Hamr. It’s shorter, lighter, handier, and inside of 250 yards more than enough for hogs and deer. It’s still no 308 or 25-06 but it’s close enough for this old man who hunts at under 250 yards it’s my first choice. The 6.5s just left me unimpressed in the field regardless of how ballistically superior they are.

That hammer does hammer them in there. Glad for the second Grendel group since I deer hunt with a 20 inch one and get good accuracy with it.

The 300 H'mr seems like the 7.62x39 at home. Really seems like the optimal .30 cal for the AR platform.

Dave. Good video and shooting. Three great groups. Thanks for sharing the performance of the two guns. Take care.

Good Shooting Dave. Thanks for the comparison. Good information is always welcome.

Great groups with both with both Wilson Hammer barrels. I have a 16" Sanders 6.5 grendel upper with same results at 100 yards with my own reloads using 123 grain SST bullet and CFE 223 using 31 grains. You should be getting much better groups with you 6.5 grendel with that long barrel. Thanks for sharing.

Dave, Im glad you explained the difference between apples and oranges lol. Dont you just hate it when your rifle makes you out to be wrong. Great Shooting Dave . I like the shirt.

Meanwhile, back in the safe, your 25-06 is complaining to your 300 Roy, "aww...he never takes us anywhere anymore. " 😅 thanks, Dave!

I'd like to see some velocity and accuracy comparisons using hammer bullets. Love the content thanks for the videos

Great video Dave

He's back! woo!

Ooh Ill be back ta watch this one!!❤❤❤

So about the same bullet grain and velocities and accuracy with the right load , the grendel just has more ballistic coefficient for longer range shoot capability. Less drag and wind drift.

Well done :)

At those speeds, the 300 will hit a little harder, but the Grendel will carry the speed and accuracy down range a good step farther. So, the question is, what's the job? Long range performance or shirt range? Great videos, Dave. Now I told my wife I need a 300 hammer...ya she laughed, and laughed and laughed some more.

Grendel for me

If .300hamr was as popular as .300blk I would have gone that route. But alas, .300blk just caught on

Yup, America is THE .30 caliber nation.

What if you lower your load of the 107 grains grendel to the same 2600 +/- fps you're getting with the 120 grains spear ?

Now you have me wondering how fast an 18" 308 will shoot various loads and can it match in accuracy to what you displayed here 🤔

I got a couple boxes of the Sierra 107 TMK. I’ll let ya know how they do out of my 6.5 Grendel with a 18” barrel….

Is the 300 hamr not basically a 300 blackout

What powders did you use?

That is shockingly bad accuracy with that barrel-bullet combination! Glad my Grendel does a whole lot better than that!

300 Hammer is in a standard AR15 upper?

too bad there is no data for reloading 300 Ham'r with heavy projectiles. if not I would trade my 300BLK for Ham'r

Im not seeing the difference between 300 HAMr and 300blk. They look almost identical. HAMR os loaded a tad hotter but with those stubby bullets I doubt it makes much difference on game

Can someone offer a ballpark guess or estimate of the energy on target between these two calibers? And Dave, what is your estimate of caliber vs speed? I know my little Grendel doesn't make very large holes but if it's faster than my blackout is there an appreciable difference? Guess I should add . . .I'm talking about killing power on hogs using hunting bullets and under 200 yards.

First !!
