270 Winchester: 150 tsx vs 180 woodleigh weld core ppsn

[Roadkill2228]

I've worked up a load with 180 grain woodleigh bullets in 270 wcf (there's a separate post about that. The 150 tsx is supposedly needing a 1:9.5 twist but if my 1:10 can stabilize the 180 (confirmed) and supposedly the crazy long 150 ablr, it will stabilize the 150 tsx too (yes I know mono metals are longer for weight but even so...). My question to you is which do you think will out penetrate the other. 150 tsx vs 180 weld core. Also, at lower impact velocities (2000 fps) which will still be able to affect broader wounding, greater expansion? Looking for the ultimate .270 moose hammer for full on chest shooting (through bones) at less than 200 yards.

I can shoot the 150gr ABLR in my 270 and I took pretty nice high country mulie buck here in Co with it last year. Due to elevation I live and hunt I can shoot bullets longer than 1.300" and 24.5" barrel does help

I read your post about getting 2600fps with those 180gr but that's at the muzzle. At 200yds your at very low end of the expansion and to me that's a gamble. I have other rifles so me I won't chance it.

Prior to using 150gr ABLR I use 140gr TSX in my 270.

I forgot to mention the Nosler Partition 160gr for the 270/270Wby

In a 270 I'd either use 150 gr Partitions, Accubonds or 130 gr TTSX's on game larger than deer. You don't need the 150's in copper. The 130's will likely penetrate just as much and with better expansion. Also, the TSX in calibers 30 and smaller have a reputation for poor expansion anyway. The TTSX was made to improve expansion and 130 gr is the heaviest offered in 270.

My take on the 180 gr 270 bullets. I'd think of them as solids for big bear defense where you want max penetration and aren't worrying about expansion. Don't over think this. People have been killing moose with 30-30's and most all center fire rounds quite handily for a long time. Any decent 270 bullet placed in the right spot will kill one.

This is in 30 caliber, but the bullet on the left is a 130 TTSX, the one on the right is a 180 gr Corelokt. The 130 fired from a 308 at 3050 fps and the 180 fired from a 300 WM at 3050 fps end up doing about the same damage. After impact the copper bullet still weighs 130 gr, most 180's at that speed will weigh 130 gr or less. The heavier bullets perform better at distance.



Why you need speed with copper. The 1st photo is Nosler Accubonds, the 2nd photo is Noslers all copper bullet. The Barnes copper bullets perform almost the same.

Bullwinkle doesn't require special or premium bullets to kill cleanly.
No bullet will work well if it hits a bone either. Probably break said bone, but the bullet will also likely disintegrate.
In any case, the ultimate .270 moose hammer is the bullet your rifle shoots the most accurately. Not the one that is the most exotic. 130's ad 140's have been killing moose for eons.
