The 90gr ELDX is another good option for a 1:10. The 90gr TGK is marginal in a 1:10 and likely will not work.

Don't believe this?, put up a really big target and I mean big a1 sized at 200 metres and fire a few rounds at it, go look at the holes if there are any. You'll be a convert

The only thing you will get is heartache unless you have a tight twist. Look at the US gunsites . The common complaint is that Sierra never put bold warnings that they needed a tight Twist. Sierra could have taken a cue from Hammer which clearly states the minimum twist requirements for their projectiles. What is hard about that. Sierra spend all the money on development for a new projectile and ignore a simple thing like twist requirements. Sierra if you read FB get a regular flogging from hunters.

I don't have a box of the 6mm 95 handy, but is it not labeled like this?

The website clearly states 1:9" minimum required

Yep you're dead right it does after we double checked it.

It's just been a learning curve for me with this thread. Like why a 95gr Targex will stabilize and the Sierra won't despite being the same weight albeit different profiles. Thanks for the info I've learnt a bit!

An example of the profiles is the heavy for calibre roundnose projectiles.
Like the hornady 117s in 25 cal.
Think that's right.
They are actually quite short for the weight and are meant to stabilise in the slower twist older rifles.
The opposite of the newer high BC long jobbies

Targex make a 105 that will stabilise in a 1:10 (you need to ask for them specifically cos there is a 105 for faster twists too).
