If it's the IMI "razor core" OTM 77gn stuff I have not seen any in SE MA. Picked up some on a group buy
For what it's worth I tested it against hornady and PPU 75gn match....PPU DID the best.
Shot from my RRA NM rifle from a rest.... also the 75gn Wolf Gold ammo is hard to beat for the price.
Is the twist on your rifle 1:8?
I reload my own version. Anyone have ballistic info on the load?
Only thing I found is the velocity i2700-2750 fps @ the muzzle. Sierra matchking bullet with cannelure.
OP keep your eyes open for black hills OTM ammo it's essentially the same thing.
No idea what bullet Israelis are loading could be a sub,par knock off of the match king?
Looking through my records last night, the closest I ever got to 2700 fps was with 23.7 grains of Varget. At which point the cases started to get trashed and I was getting random fliers
I dropped the charge down to 22.5 and am getting 2550-2600 fps and was getting accurate groupings at 200 yards.
The ballistic chart revealed that comparing the two loads, the later begins to drop off at 300 with the difference at 500 yards being 12.5".
Even though I don't shoot that far, I live and shoot near the ocean and a cross breeze is always a factor and the heavier bullets stabilize better in it.

Accurate Powders seems to be about the only mfr. that lists 5.56 data. The 77 gr. Sierra MK is used in their tables...

Of course, all of this is completely off topic...I'm just looking to buy some IMI 77gr. locally.
Say--has anybody seen it for sale locally?
Is TAP still running 1$+ a roundI've found 77 Sierra and 75 TAP online at a couple MA friendly vendors. Just gotta do some investigating.

Is TAP still running 1$+ a round
In case anybody is interested, I found some at Cabelas the other weekend.
Cost is about $20/20 rounds--not a great price, but you'll know how it shoots through your rifle without buying 1K rounds of it.
Let us know if it's worth $1 round?
to answer your question....
IMI razor core 5.56 77gr BTHP
1:7 twist, 16" barrel, 100 yards with 10 mph crosswind, shooting off a table + bag

I've obtained very similar results from a 1:8 twist. the ammo is very consistent. from 1:9 twist the group opens up to just over 1 MOA.
