Both rechambered tikka 708s.

One is a T3 cut to 17" with DPT magnum suppressor. Long mag and bolt stop.

The barrel was throated long to suit 162s seated out in the neck.

I run 162 Amaxs at around 2700 fps which kills really well near and far. I use H414 powder.

The other one is an older tikka M595 with a factory length 22" barrel. Also throated long.

I always just use to run 150gr NBT to fit the fairy short magazine at just shy of 3k which worked really well.

I've recently fitted a T2 brake to this barrel and am experimenting with 180gr eld-m's.

They shoot super well with IMR 7828ssc at 2760 fps.

But have just this morning shot a ladder using RE26.

These are the results.

They're getting along pretty well.

56gr 2789 fps
56.5. 2820
57. 2841
57.5. 2859
58. 2869
58.5 2906 (click at top of bolt lift and very flat primer)

Looks like it's going to group well in the middle of the range around 2850 fps.

Run the numbers on the 180 eldm at that speed, pretty awesome performance from a 22" 284.

My chamber has a very long throat and I can seat the 180s out nice and long. COAL of 3.257 inch.

Don't go trying these loads with a shorter throated barrel. Start lower and work up.

Fuck that's impressive speed/ballistics. What twist rate? Standard 1:9.5 tikka?
