75 gr .223 ammo . . . increased problems feeding? Yes? No?

[Mean Bone]

I found some 75 grain HPBT .223 ammo at just over a "buck-a-bullet" when shipping and taxes are included.

My concern is that I may have an increased possibility of feeding problems. At that price I'd rather not find that out on my own (although I may have to).

Do 75 grain rounds have a history in this regard? I don't have an overall length for this ammo.

I'm running a MilSpec 5.56 BCM RECCE16 with an M4 ramp.

If it's hornady frontier, its excellent stuff.

COAL will be magazine length.
I've shot 3 versions of 5.56 77 gr OTM; BH, IMI, Magtech.
No problems.

I have a BCM ELW 16" that has shot everything from 55gr - 77gr. Quality ammo, even reputable quality bulk ammo, should work great anything within that range.

A related item is for defense loads I'm using the Speer 75gr Gold Dot, super accurate in this barrel and highly recommended.

I’ve shot quite a bit of IMI 77gr and have never had feeding issues, popped primers yes, but never feeding issues.

[LMT Shooter]

I shoot Hornady 75gr BTHP a bit, and their 70gr GMX some, and I've never had an issue at all.

I shoot Hornady 75gr BTHP a bit, and their 70gr GMX some, and I've never had an issue at all.

Same, thousands of them in several rifles, single and mag loaded, never a feed issue at all.

all my rifles have the M4 cut for receiver and barrel extension.

Assuming Hornady and Speer load data OAL carries over to their manufactured ammo it isn't always mag length. Looking right now and only the 5.56 pressure 75gr gold dot is shown 2.260" mag length while .223 gold dot and all of the Hornady are listed shorter.

Which did you find the most accurate?

The only thing 75 grains tells you is that the bullet weighs 75 grains. Nothing whatsoever, much less predictive, can be deduced from that without further information about the bullet particulars, cartridge OAL, charge, manufacturer, etc.

Not a comment solely on your post but the whole "XX grains isn't reliable/accurate/whatever" needs to die.
