Monometal bullets for Deer

[Scrumbag]

Hi folks,

Anyone used any monometal bullets in the 257 Roberts on deer?

Thinking mainly using about 100gr weight.

Any thoughts on TTSX or Nosler E-tip.

KR,

Scrummy

I haven't used 257 Roberts but I have used a tipped TSX in 30-06 several times with good result and my son has used the plain TSX in 243. We have both had excellent results. I imagine 257 being between those two would work well also.

I have the deer have looked very dead from the tsx.

 

[Scrumbag]

That's good to know, anyone tried the e-tips. Seem to be easier to get locally.

 

[thriller]

I have not tried those.

 

[wislnwings]

I have in 243 with success and a friend used them in 257 Robert's with no complaints.

I have had great success with 80gr TTSX bullets in the 257R/25-06 and 257Weatherby. I have some 100 gr TTSX to try in the 257Weatherby but since the 80gr ones work so well I have not tried loading the 100gr bullets.

The e-tips are much like the old Barnes X-bullet and it was a poor design. I love Nosler Partition just wish they would cut some relief grooves into the E-tip bullets.

Use TTSX and not the TSX. Seat them deep---to the top relief groove. Push them fast--seems the faster I push them in any caliber/cartridge the more accurate they are. The faster you push them the better the terminal performance is. Go lighter weight bullets than you usually use--they work like a lead core bullet 30% heavier--they also expand better.

We have used the TTSX bullets for deer/hogs and a sheep so far. Took a 30-06 with them to Africa but never used the rifle. I used a 338win mag with 225gr A-Frames and my daughter used a 257R with 120gr A-Frames---everything died and tracking was not required for more than 80 yards on any animal.

80gr in a 257 bee, holy lifting Lizzy how fast are those moving

 

[Divernhunter]

In my MKV with 69.5grs IMR4831 I get an ave of 3749FPS and very accurate. Using RL22- 71.5grs- I get 3702fps.
Using RL25 -73grs- I get 3695fps
Using Win780--71.5grs--I get 3655fps

Using the 100gr TTSX I get 3715fps using 71grs of RL22 and it is very accurate and 3603fps using 68grs of IMR4831

In my 264win mag using 100gr TTSX in order of accuracy:
74.4grs Mag Pro--3644fps--one hole group for 5 shots
65.5grs RL22--3529fps
71.6grs Retumbo--3464fps

These are just a few of the ones I have tested in a number of different cartridges/rifles. I have yet to find a cartridge/rifle/pistol I could not get an excellent load for and usually with very little testing.

outstanding velocity close to my 204 ruger. must be instant death on deer and speed goats

I once fired a 257 Wby loaded with a 60 gr Hornady flatpoint (designed for the 25-20) over a chronograph. The velocity 15' from muzzle was 4500+fps. the barrel had a 1-10" twist and the bullet didn't make it to the 100 yard target- appearing to disappear in a cloud of grey smoke about 50 yards from the rifle. I didn't shoot any more of them.

I had a Hornady 50gr spsx in 223 do the same at 3100 out of a 1:9 223. quite spectacular isn't it?

I load the TTSX 100 Grain in both my 257 Roy and my brothers 25-06. Outstanding results on deer, pronghorn and caribou. I would have no reservations whatsoever. Never used the eTip or GMX as I didnt see the need with the performance of the TTSX and TSX previously experienced. As stated elsewhere, seat to the last groove on the bullet. They seem to like a little freebore for best accuracy in my rifles.

I am curious what kind of velocity a .220 Swift could achieve with a 50gr GMX. It would obviously hold together through the air because it's a monometal bullet, and I predict that it would shear the petals instantly upon hitting game at closer ranges, but may well be absurd at longer ranges.

I have heard a 0.050 jump is preferable. The OAL of the 70gr TSX that I have which was loaded for the military in 5.56 is @2.241"

 

[Divernhunter]

^^^ Even more jump is good. I have a number of rifles/Encore pistol barrels with .080 and more. The Weatherby rifle have a lot of freebore with any ammo. I have over .200" with my 80gr TTSX or with Weatherby factory 80gr TTSX and get 5+ shot into one large (3/4") hole. Load to the last groove is the smart thing and if you look at the factory ammo you will see they do so also.

 

[Rule 303]

I have shot a Red stag with a 358 185 grain Aust. Custom Projectile-sort of hard to get now- out of my 35Sambar at 6meters. Bit of a dead right there. Also have shot several Camels with them as well. No complaints from me or the camels. I think Graffs stock these in the US.

Use TTSX and not the TSX. Seat them deep---to the top relief groove. Push them fast--seems the faster I push them in any caliber/cartridge the more accurate they are. The faster you push them the better the terminal performance is.

I suspect that the velocity/accuracy relationship in this instance has to do with better obturation at higher speeds. I say this because I have a couple of friends who use Hornady SST bullets (150gr as I recall) in their .303 Epps hunting rifles (Yes, there is an SST bullet that works in the .303, possibly made for the Argentinian market). They have to run the bullets up to 2,900 fps to get good accuracy, obviously due to obturation issues with the relatively short shank on those bullets.

I checked 165 300wsm, 160 TSX and 150 TTSX in 7mm mag and you are 100% correct the factory loads are seated to the last groove

 

[Divernhunter]

Yes I checked about 10 different cartridges at the gun shop and that is what I found. I checked 2 different brands also using their bullets. Then I loaded mine the same way and the accuracy improved greatly. I also spoke to the people at Barnes a number of times while figuring out the best loads for me and friends/family. This is why I posted that.
