Finding a lot of conflicting information as to whether they will be stable. In some of Hornadys own literature they omit twist rate completely and in others it says 1-8 minimum. However JBM has it stable.
I know that length shouldn't be a problem as I believe they are specifically designed to fit AR mags.
Any gurus able to share input?
I use these in my 18in tikka. No issues.
Target at 100mtrs with the 73g ELD m. Shot off to the right is a different weight bullet.

Is your Tikka 1-9?
Tikka is a 1:8 twist, subtle difference that would helpQuote:

As far as stability goes, you'll just have to try it.
General rule of thumb is usually 1:9 twist are only good up to the 69gr bullets but that isn't gospel.
If the stability calculator says you are ok then give it a ago.
I'm currently working on a load with the 75gr BTHPs in my 18" 1:8.
Am getting around 2750 with either Benchmark 2 or ADI 8208.
2208 was super slow.
Yeah now I think about it it is a 1-8.
Yeah 73's ran good in both 1:7 and 1:8 AR's.
I tried running them in 1:10 22.250, thought I had a couple of excellent results but then couldn't repeat, so dropped back to 69tmks and were excellent tiny groups.
Getting more revs on with the 22.250 helps to Stabilise vs 223 though.
They'll probably work fine
If it stabilises in the formula they should work as long as you are putting correct numbers in for speed etc.Quote:

Fwiw I can get 73 eldms but not seeing any 69tmk around so hence the point of the post
Back in the far off mist we cowboys had firearms with either six or eight inches up front , I see most are cheating now, going for sixteen or even eighteen, shock horror, no more sneaking up just blast them from 50 paces. Lol
I'd just give it a go, the ogive on the 73 is supposed to be a bit more forgiving that's why I tried to get them to go in a 1:10, bit more work may have?Quote:

It kinda depends on the cartridge. I'm pretty sure with the slippery 90 and 100 grain bullets on 6mm, marginal won't cut it but with the larger bullets like 7mm and 308 they will stabilise. And also sometimes we just get lucky :DQuote:

About $62-$65 per 100Quote:

i use eldm 75s in my 18inch 1-8 tikka.
Hi there, just noticed this & thought I should chip in that my prices will all be going up approx 10 percent due to jacket prices from the States, our dollar & everything else that is going up.
Have tried to hold them back as long as I could but I'll have to move them or stop making them.
Sorry everyone that gets them off me but doing the best I can for you.
Still a lot cheaper than Berger bullets in NZ & I'm using their jackets to make them for what it is worth.
Cheers, Bryn.
