7mm 120 ttsx

Started hunting with it couple of years ago in 7mm-8 and killed few antelope and whitetail deer with it. Powder I use is IMR 4895 and Varget and my groups run between .500 to .750. Just remember that Barnes bullets expand better under higher velocity. I believe 120 TTSX needs about 1700 fps to expand properly.

Barnes recommends 1800 fps, advocates suggest 2000 fps.

I can tell you from experience the 120 NBT is an angry little bullet.

There you go, my full load gets approx 3000 fps and reduced load will get probably 2800 or less so it might work, but I had Barnes 165 TSX not expand in 30-06 at approx 180 yards and 2500 fps on mule deer.
 
The OP needs to understand that monos need speed to expand, so creating a low-recoil load with the 120 tax will limit effective range.
I was looking to see if anyone would mention this. Barnes claims the 120gr will reliably expand down to 1700fps. If this is a shorter range rifle I guess it would work as reduced recoil bullet.

I myself would prefer a full power load or a less horse power cartridge.
 
I'm shooting Rem 700 Mountain which weighs 6.4 lbs with scope in McMillan stock, with the left hand resting on the scope the recoil is very mild, unless I have a heavy hand.

Yes for sure. We are not looking for a reduced recoil load anymore, just thinking that a 120 grain should produce less recoil than a 150-160 grain bullet. And if the 120 will do the job for now on deer and antelope, then why not try it.
 
In my OEM Tikka T3x, the 120 NBT over 44 grains of Varget at 2.810 COL is extremely accurate and very soft shooting. According to Bison, at roughly 3,000 MV (I have not chronoed, but estimating with 22") it delivers 13ft. lbs. in a 8.5# rifle. I have a Limbsaver on my Tikka and was comfortable shooting this load in a t-shirt prone off a bipod.

First 10 shot group with this load attached.

*Rough* recoil numbers for 150 and 162.
