108 eldm factory tikka 1:8 twist

[Mulyhuntr]

It's been pretty solid. I've gone lapua in other calibers and it seems better in terms of sd.

I think your done, that’s great. I have a stock on the way and then hopefully I can duplicate that group. 22” tube so maybe a few more fps.

Nice work

That’s awesome performance. I’m getting heavy ejector swipe at 40.5gr in virgin PPU brass. Not sure what the speed is, but hoping it settles in after its fire formed. I’m at 16inches otherwise same specs as you

I was starting to see a little pressure at 41g of h4350 with virgin perterson brass, it was shooting 1.5moa for 10, 40g was .6moa. I didn’t check velocity yet but I’m assuming I will settle in around 40ish even after it’s fire formed.

That’s some great performance! I think I’m going to switch powders to h4350

Interesting. I see a lot of folks running 41+. I’ve loaded enough to know it’s different for every rifle, but interesting either way. I’m not getting to cute with it until all the brass is once fired and the barrel has 50rds or so.

I was expecting to go higher myself, after trying 109s and getting nowhere I just loaded these 2 charges with the 108s to see if they would show any promise. I’m thinking I could safely run the 41g load but I would bet at 41.5 I would start to see a faint swipe, I was starting to see the slightest ejector imprint at 41 in the right light.

Little bit different but same projectile, my 18" 6 creed is pushing 108eldms 2960 with a case full of n555 with the accuracy you're looking for.
