Best TTSX bullet weight in .270?

You look at your RF then get a slide rule out "re check" go click click click, look up to find it has ****ed offCouldn’t tell you, never used a ballistic turret
How does that work?
Explain how it can be too fast when the bullet holds together , Worst i have seen is an odd single petal breaks off once in a while and that will happen with all copper unless its a none expanding solid !

Fired a 110 grain TTSX .270 into two 20 litre drums full of water laid end on on the ground at 80 yards. The bullet went through the first drum and came to rest in the second drum having mushroomed to approx .45 cal. Put the bullet on my RCBS beam scale and the bullet weighed 109 grains. Even at 3350 fps, it only lost 1 grain of weight….
yep! Exactly what you get I think you just lost the tip with that 1 grain LOL ! Unless a petal meets bone at the correct angle.

I speak from experience, i’ve said it before numerous times and I’ll say it again, I’ve never used light copper bullets and I’ve never driven them fast!
Never wanted to and never seen the reason to!
Sometimes you have to think out of the box and learn from experience instead of reading the line BS and following it!
Like I’ve said again numerous times I’ve shot copper well over 15 years and I’ve got a massive heap of dead to tell the story and I’ve never driven a bullet over 2960fps or under 130gn

What cartridge, what distance and what MV?
I find the copper rounds totally adequate, no issues, but I don’t see the point in driving them fast, anymore than I see the point in light for caliber lead rounds.

It’s quite cool that you .270 users are turning them into .25-06’s in effect! Just saying…

MV 2900, ttsx 95gr 57gr RS 62, distance 25yards up to around 250 yards. Fast=Flat trajectory, slow copper apparently doesn't work to well for bang flop, or so I'm lead to believe.

That’s not particularly fast, in fact it’s just about bob on ( in my opinion).
“ FAST” would start at around 3,500fps, which is what you get with light bullets in .270, .243, or the hot .22’s.
I don’t subscribe to the light for caliber, high velocity trend with copper bullets.
I find bullets in the 120 grain range perform very well in my rifles, with good lethality and excellent penetration and accuracy.
I shot deer for over 20 years with a variety of center fire .22’s, bullets from 45 to 73 Grains, they all featured high velocity, close to 4,000fps in some cases, they all wrecked a lot of meat.

I agree 2900 seems to be about spot on for the stalking that I do. However consistent accuracy is essential too. With lead in 270 that's usually in the region of 130/150gr but I was coming at it from a different perspective. I used to use a 243 for all my stalking with 90gr accubonds, on switching to copper 90gr won't stabilise in my rifle so I went to 80gr, fine for accuracy and up to roe size, but the fallow were down but not always dead. In switching to 270 I was trying to replicate the 90gr 243 accubonds, a limiting factor at the time being the non availability of 110gr ttsx and having got the 95gr ttsx to perform both in terms of knock down and accuracy I've stuck with it.

^^^ Exactly. With 100gr Norma my .243 was usable on all deer. Going over to 80gr TTSX copper, the .243 is now only roe & muntjac for me but a delightful Summer month gun. Was getting a lot of meat damage with my 130gr TTSX .308 rounds so I have been increasingly using my .270 but with 110gr TTSX on fallow and reds.

I’ve been using both 130 and 120 Sako factory copper for a few years. The bullets are long for their weight and penetration is unbelievable in comparison to traditional lead core rounds, it’s so good, in fact, that I’ve only got one back so far.
I’m personally not a fan of the .243, particularly on sika, I’ve seen it fail far too often, but there’s no doubt that a copper bullet of around 80 Grains would counter one of my biggest gripes with the cartridge by exiting. Something that generally doesn’t happen with traditional cup and core rounds.
