Douglas Barrel Question

[RomanLove]

Gents,

Have a question regarding what twist to get for the Douglas 18" barrel. I will be shooting primarily the heavy grain ammo 69-77 out to effective distances, but I would also like to have the option of shooting the 55-62gr. I'm looking at a 1:7 or the 1:8 Douglas. I know the faster twist is better for heavy and vice versa. This is for a PRI Mk12 MOD 0 btw.

I want to know specifically for this Douglas barrel not other barrels.

Would the 1:7 be the best since I'm shooting primarily 69-77? Or is the 1:8 going to offer the exact same accuracy out to 500 meters?

Is it a marginal difference between the two for heavy bullets? Also, since I do want to be able to shoot the 55gr, will the 1:8 offer better accuracy to 300+ meters over the 1:7, or same?

Basically, I don't want to get the 1:8, and later on say I wish I had gotten the 1:7 b/c I would be getting better MOA's right now.

Thanks for the comments.

I would go with 1:8 if you're looking to at all shoot over a spectrum of weight like that. That's what the Wylde chamber was ultimately designed for as well.

I use 1:7 on mine to shoot 69-77 and I use a 1:12 to shoot the 50-55. To me, 55 gr is pushing it in a 1:7 and therefore I would recommend 1:8. I have a Mini SASS in 1:8 and it'll shoot both PPU 69gr match and Hornady 55 gr v-max very well.

My PRI has done well across the spectrum. I would leave the 1:7 alone.

Let's say I only shoot 69-77, would you recommend the 1:7 over 1:8 then?
thanks

You went with the 1:8? What kind of MOA to 500 meters with the 69-77?
thanks

If you only shot 69-77 then yes, I would go with the 1:7.

I went with the 1:7. I meant leave it alone as in 'good enough.' I am between 15-16 MOA drop at 600 yards if memory serves me correctly.
