338 edge

[steviebby]

Hi there simple question I'm building a 338edge , is the standard twist rate of 1in10 good for the 300grain projectile range?

 

[dgarrett]

yes

Yes, Berger recommends 1:10" or faster; I went with 1:8" on my latest .33 cal build.

.338 Thor (NMI) with 300 Berger at 3.7" COAL touching the land.

I have had several 338 Edge Rifles . Carbon and Steel Barrels they all have 1/10 twist and I ran the 300 gr OTM and EH but I have only been out to 3027 yards
( 1.72 miles ) so far !!!

1400 yards should be my max distance

The Edge is just getting warmed up at 1400 yards !
Just be careful... your going to really injoy that 338 Edge it's a thumper on Game !

Uh. What exactly is the moa cant you have there Rum man?

If you plan on all copper bullets, check out the recommendations at Hammer Bullets. Their 285 grain Hunter requires a 1:9" twist. The bullet is 2" long. 10 inch twists work for lighter bullets. I believe that similar restraints occur with CuttingEdgeBullets.

Well they way that one was set up is has almost 325 min. Of Elevation !

55 moa Nightforce base, 200 min. Valdada adj.base and the Razor with 125 min .

It would have been in the low 4000 yard range totally turned up !
Now I'm pushing the 300 gr . berger alot faster . I'm positive that would help for distance / Wind .
Just ran my old numbers in Shooter , my max would be 4264 yards !
Things are different now with my load .

Don't remember if you mentioned before but where do you get that distance at?

..the Edge will toss the 300 a long long way...big thunder and lightning.

If I was building another, it would have a 9" twist as mine did. You can go 8" twist, but don't think it's necessary.
I don't know what you want to do with it, but don't expect a great jump in velocity over the 338RUM.

Cheers.

I think you should adjust your neck tension. Looks a little off.

It was back in Montana.
I just shot a Buddys 376 Cheytac out there two weeks ago ! We were looking for 3000 yards plus but the weather wasnt working out . I did get to shoot it at 1030 yards that day! Good Times !
