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

Around here, magazine mods are plenty common...grin.

As to design where lands are out of reach...Liability is the only explanation I can think of which makes sense...

DJ

Well, on the 8400's you can reach the lands, so I don't think that's it.

How would you mod your mag if you had one like mine?

Mag length is the only complaint I have with my Montana. And given the way it's shooting, now that I've figured it out somewhat, it's a very minor complaint.

DJ,

Saw in another post that you've tried the TTSX. Results???

Thanks

Never moved the die from OAL which shot well with the NBT, loaded the same charge (50 grains) of Big Game (just to see what it would do, and if I could basically run same OAL with both bullets - although they are not identical OAL, should be pretty close to the same on the Ogive), and it shot over .5 but under .75.

Could hunt with it just like that, although I may play with OAL a bit and even run a little more powder since the TTSX's like to be pushed and I had no pressure signs at 50.

But - how handy would it be to throw and go with both bullets with a powder that meters as well as Big Game???? Grin...

IME, the TTSX's will have less pressure than a NBT - reckon it must be bearing surface...

DJ

It will be very interesting to see the results when you get them over a chronograph! I just bought a big jug of R15 but this Big Game might get a go in my 7-08's. One just might like the BG better...

52BG and a 700 MR 22" does 3164, kimber 22" will do a bit better

do like BG...but no worries about RL15 in the inventory...:)

DJ,

I've been watched this topic and decided to give Big Game a try.

50gr Big Game, 120NBT, WLR primer, 2.855 OAL.
Marlin XS7 22" barrel

UNBLIEVABLE!!!!!! 3 shots + 100yrds = 1 HOLE

Curious as to what load you were running before?

I had only loaded reduced loads for my 9yr old. After I saw him kill 4 deer with his in the past two years I decided to buy myself one and give it a try.

Funny thing is, I never thought the first trip to the range would give results like this.....

I have rifles that cost a lot more but this one is just as accurate.

Bump

DJ,



Have you tried anymore TTSX's?

If so, what was your outcome?

DJ, I have but one question, why are you running WLR primers, one of the hottest primers out there? Im willing to bet youd shrink your groups if you tried CCIBR or 9 1/2 primers.

I was wondering the same thing, those groups are just too damn big.

No better than I can shoot, I don't know if I'd see much difference...grin.

I just ran the WLR's because I have a bunch of them. They may have something to do with seeing such velocity without a max load, though.

I may play with some others when I can get them.

It's nearly too hot to work up loads around here right now.

You boys in the cool will have to continue the research for a while, I reckon.

DJ

Thought I'd bring this one back to the top again. Ran 52grs. today in Virgin RP brass with WLR primers. At 125 yards, over my backpack, 10-15 MPH wind I hung a dimed size three shot group out of my first genertion Ti.

Almost feel bad that I still have two loads to shoot with R15, it's like I'm wasting bullets or something.

Loading some up tonight with NBT and TSX, hope to shoot for groups and crony this Sunday..

Question for you guys as I don't have any load software.

Running the 120 NBT at 3,100, with the rifle sighted in 2" high at 100 yards, what is the drop at 300 and 400 yards?

Does it make much of a difference in drop vs. 3,000 fps?

I did not know what elevation you wanted, not much difference out to 500 yards.

I ran the info at 3000 feet elevation.

120 grain Nosler B/T BC of .417
Speed 3100 fps.

2" high at 100 yards with a zero at 234 yards.
300 yards -4.24
350 yards -9.07
400 yards -15.43

Same load at 3000 fps.
2' high at 100 yards with a zero at 225 yards.
300 Yards -5.15
350 yards -10.45
400 yards -17.39

Then I checked the elevation at 1000 feet with the 3000 fps. load at 400 yards it was down -17.88 not much difference at 400 yards.

Hope this was a help to you.

Happy Hunting

Randy,
Thanks!
