thanks

If you compare that load to Federal�s 165g Tipped Trophy Bonded or the 180g MRX or AccuBond you�ll find out there is a price to pay for little gain in the trajectory department.

Using Federal�s own numbers:

130g TTSX, 3500fps, 3536fpe
165g Trophy Bonded Tip, 3050fps, 3408fpe
180g MRX, 2960fps, 3502fpe
180g Trophy Bonded Tip, 2960fps, 3502fpe
180g AccuBond, 2960fps, 3502fpe

Zeroing all for 200 yards, at 500 yards they look like this with a 10mph crosswind:

130g TTSX = -30.8�, 1383fpe, 7.9� drift
165g Trophy Bonded Tip = -37.9�, 1577fpe, 18.5� drift
180g MRX = -37.6�, 1872fpe, 15.3� drift
180g Trophy Bonded Tip = -38.9�, 1745fpe, 11.2� drift
180g AccuBond = -38.7�, 1763fpe, 16.8� drift

For myself, I don�t consider the 7-8� additional drop of the other bullets to be significant. More important to me is the extra energy they carry. The 130g has less wind drift but again the 3.3� difference between it and the 180g Trophy Bonded Tip isn�t very significant � I�ll take the extra 362fpe of the Trophy Bonded instead.

Here's a good link for looking at drift and drop:

hmmm, the 130gr TTSX has less drift and drop, what's not to like? The energy figures don't concern me a whole lot as long as the energy is sufficient to open the bullet and destroy some tissue, which it is...

Energy figures I looked at for the 130gr TTSX showed 1510 fpe at 500 yards. Still less than the heavies, but not quite as dramatic.

Almost looks like this load takes the .270 and extends it's range out about 100 yards. I'll just add 100 yards to where ever the 270 stops being effective on elk and call that the maximum effective range for this load. Where does the 270 stop?

I could say something silly - like "use a 223" (since I have watched it be used to great effect on moose and caribou), or I could just offer a couple of examples of heavy bone encounters...



Second from left: around 200 yards; muzzle vel: 2900 +/- 225 XFB (.338) moose shoulder; second from right: around 275 yards (est); 160 7mm FailSafe, MV 2500 +/- moose spine. I won't bore you with any more re-runs but have similar even from caribou. (Not disparaging copper bullets since most of them do exit.)

Big Bone = Brakes, even, sometimes, for bigger bullets. Lots of things can; doesn't mean they reliably will. Monolithics haven't reversed any of the physics involved in the collective wisdom of the decades. You decide.

I have STRONG suspicions that the 130 TSX at 3500+ fps at the muzzle will do some very serious bloodshotting at anything under 200 hundred yards---deer, elk, whatever. Could be wrong....I was once before ;0)
I'd just as soon have some meat left to eat. If it were me, I'd choose a heavier and somewhat slower bullet.
A 180 (or 200) will shoot flat enough to make 350-400 yard shots a practicle reality.
Just my $.02

glancing at sir springers shot... bullet going into shoulder on close range shot, but no evidence of exits... add that into the the wind drift factor that folks seem to always forget about, I'd pass.... 168/180s for that caliber. Just IMHO.

Want a test before then, use your choice, go a bit south and shoulder shoot a nilgai or at a sweeping angle and see what it does.

Which 270 ? My 270 Weatherby Mag is starting out a 130 gr.
@ 3450 FPS.

Is that a typo on the wind drift? What bc did u use? I guessed .400 and used the link above with different results but may be wrong. Thanks

This would be taking things to nearly the opposite extreme, but try running the numbers for a 200-gn Accubond at 2900 fps with a BC of .588... I've shot that exact load quite a bit at longer ranges and it really drills through the wind...

The AB is a generally accurate bullet; it's done very well in 6/7 of the rifles I've tried it in. It's lethal as all hell, too.

FWIW, the 130 TTSX is what I use in my very similar 30 Belted Newton rifle. So long as you are shooting an Elk in the chest and not trying to go end to end the 130TTSX is a great choice at all sane hunting shot ranges. If one needs to push a bullet from end to end on an Elk, the 180TTSX is without peer. BTDT (On a KUDU, but the need for penetration is nearly identical). For Elk out to 400 or a little longer my preference would be the 180TTSX but the 130 would be great for the more common shot presentations.

Ogden/Liberty "area", i take that to mean Rulon Jones property?

Rosco,

That's correct. Having never hunted there before, any firsthand accounts would be appreciated.

My ballistic calculator shows a drift of 18.2 inches for the 130 grain bullet, and 16.9 for the 180 accubond - at 500 yards. The accubond carries about 250 foot pounds more energy at that range.

How much flatter does the 130 shoot at that range?

How much flatter is the 130 at 500 yards - I'm showing about 9 inches, but I may have over estimated the ballistic coef of the 130 (I used 0.385).
