69 and 77 SMK ?

[rebs]

I have read that these SMK bullets were developed for the AR platform for a longer jump. What other bullet in this weight class would be an excellent choice for 300 yard F class target shooting ? My rifle is a Tikka T3x Varmint 223 with 1/8 twist ?

80Smk works well out of mine.

80 Berger would work.

I think pretty much all of the heavier 22s would lend themselves well.

I have shot the 223 and 223AI in mid-range F Class using Berger's 80.5. Other bullets work, of course, but, I have yet to find commercial bullets that are consistent in weight and LTO.

 

[Crosshair1]

i would look at the 77 tmk, I find them extremely consistent in bto and by weight, bc is not much greater than the smk, in factory tikka coal will probably be in the region of 2.4"

 

[Zero333]

I'd choose the 75 or 80 gr Berger VLD.

For 300 yards I’d go with the 69 gr tmk

Are you confined to a magazine length load, or are you single loading? Is your throat cut to SAAMI length, Wilde, or custom cut longer for heavy bullets?

I still have a bunch of 80SMK's I was using in my 8 twist 22-250, and thought about trying them in my 8 twist 223 Criterion, although it's not throated for the heavies. Currently shooting 69 gr Lapua Scenar L over Varget and getting some tiny groups. How much case intrusion are you seeing with the 80SMK in your rifle?

I don’t have a picture but I’m loading the SMK in a 223 with an OAL of 2.460. I’m using a afatermarket magazine that is built for the longer OAL.

That length puts me just off the rifling in the factory barrel.

I have the same - except its the earlier Varmint not the X version, I have used the following in it, 69 SMK/Varget shot good, needed more dev time, 77 SMK/Varget shot great at around 23.4 gr.
best ever group was just on 1in" @300m. 77 Hornady Custom Comps ( same as SMK ) but last year or two only shot the 75gr AMx / 24.0gr 4895 which also was great

I single load and load 10 thou off the lands

77 TMK

77s are designed to get the most BC out of a mag length round, not necessarily to use a long jump. That said, they’re a compact, heavy bullet and can be very accurate and reasonably wind resistant at mid range. In a bolt gun, load them as you would any other bullet. I’m a big fan of this bullet.

Any of the 80-ish grain bullets are also good, and will give better wind resistance, although I find them a little harder to get to shoot accurately than the 77.

Wisconsin Service Rifle Team year’s back put
Hornady 75 gr. HPBT on the map ..

I still shoot them , and cheaper ..

At 300 yards on a 600 reduced Target SFP .
Out or AR’s Service and Match they worked better than 80’s ...

Good Luck
