Home Forums Reloading Big Game Rifles Impressive Velocity & Accuracy - Ramshot Big Game: 7-08/120 NBT...

This is a good place for such info.

Well, it looks like I'll be right between those. My results from a 22" barrel:

50.0 Big Game with the 120 NBT, average of 3,023 fps.

50.0 Big Game with the 120 TSX, average of 3,042 fps

50.0 Big Game with the 120 TTSX, avg 3,029 fps.

Chronograph was 12' from muzzle.

Going back through my records, these averaged less than 100 fps more than my standard load of the 120 TSX with 44.0 RL15.

With 49.7gr I am getting ~3150 with the 120 NBT, out of a 22" tube.

My gunsmith's chronograph must be off. All of my loads I shot yesterday were 100-200 fps off the book and/or other shooters speeds...

Another brief update...Wind finally laid after a little rain today, and I shot a group with 50g of Big Game and 120 TTSX. I left the die exactly where it was with the good 120 NBT load, and I shot a half inch 3 shot group.

I only shot 3. They were about 3" high, so I spun her down an inch and half and stuffed the other 4 I had loaded in the magazine.

I'll try to load some more tonight since that is the second sub .75 group I've shot with the TTSX's at this COAL with 50g of Big Game. It does like the Rem brass better than the Federal. At this point, I think I'm just going to kill stuff with them except for a long range session to double check POI on a few long pokes.

Still no pressure, and I may even push another grain or two under some TTSX's when I have a chance, but I won't chafe too much if I have to run these for as long as the barrel lasts. I've got room in the mag to chase the lands over time, and enough cushion in the load to add powder if that's what it takes to keep her shooting for a few thousand rounds.

Rifle life doesn't get much better...Now if I can find a buck that figured out how to grow an over-sized rack despite the drought...grin.

I ran a 120gr. BT into a deer last night at about 40 yards...starting to think that the TTSX is a better option.

Because ...

Nothing hard and fast yet just a thought. Shot wasn't great but it was what I had at the time. Deer was nearly facing me, bullet entered just behind onside shoulder, took out back of one lung, destroyed liver, and made it into the stomach (which was really a sack of acorns). A tiny piece of the core made it into the off side ham, jacket was found in the stomach. I'm thinking a TTSX would have probably exited and gave a better blood trail, BT gave me a couple of drops of blood at initial location and nothing else until I found the deer. I of course applied the BT completely incorrectly (Pushing it had and hitting a close deer marginally) and it still killed the deer so I can't complain, but I would have liked more blood on the ground. Sample of one hasn't soured me on them yet though...

Is the 120 gr NBT inappropriate for elk?

P

Probably not if applied correctly...

Bi-Man, how was the blood when you field dressed it?

No doubt, had that happen using an M70 Fwt and a 140 BTSP Sierra in the 90s in Tensas Swamp here - 35 yd shot, deer made it about 40 yds, SAME thing in Colorado on a Mulie, 270/150 Partition, around 275 yd shot, deer also went about 40 yds....no exit, but very complete otherwise....stem to stern.

I'd be Very happy running a 120 Barnes on ANYTHING to about 350 yds or so, and a 140 Accubond on most all else, save very LR shooting, a 162 Amax might be nice.

I'm just starting to load for a 7mm08. The local Cabelas has Varget but no Hunter.

P

It's a tough little pill. IIRC Dogzapper has taken elk with it.

And moose...

120 NBT = Can; 120 TSX = Will; 140/150 TSX = MBS

Help me out with what this means.

P

I,m guessing MBS = Moose Back Strap

MBS= Mo' Better, Still


I think I've drilled 4 200 grain NBTs into broadside moose- chest shots- with none exiting; these being sent by a 340 Weatherby. I also have a fair collection of copper which various moose have stopped. Our northern moose seem to be constructed with more Kevlar than most NA animals, which is basis for that post. I know they break the ornamental ash trees and play havoc in traffic. THey are not an animal which is as inclined to run off when they've been hit as some apparently do. Even so, they still deserve quick and decisive dispatch IMO. I rank the 120 NBT along with the 223 in the 'can' division. There are better, more certain ways to do the job.

Got to bump this one up a bit....hope no one minds.

So for you guys running Big Game and the 120's, have you been able to shoot in fairly different temperatures to assess if this powder is temp sensitive in a negative way? Forgive me, for I ask here before really researching the history of Big Game Powder.

Good thread and I will be giving this powder a go with 120 TTSX bullets when things warm up here (spring).
