Is this the same upper you've been researching last few months? At least you have it narrowed down to two
I been researching both the DTECH and the WOA quite a bit

I can't see you going wrong with either choice :)Why no flutes? My non fluted 24" SS barrel is a monster to carry!

Don't you already have rings for that scope? They should work until you step up to a LaRue. ;)

Varmint weight bullets work better in a 1 in 12 twist. If you want to only shoot heavy bullets go with the 1 in 8. But with a tight twist barrel you lose some speed too. I have no problem with my 1 in 9 twist Savage but for what we're shooting the 1 in 12 is the way to go.

Also WOA only has 1:7 or 1:12 twist.1:7 is to fast for Thin skinned bullets, they will most likely come apart before they ever reach the target. Although the Savage perform's well at 1:9 I think they are pushing the limit. Personally I would prefer a 1:10But you can't argue Target's like John's B) I just finished up my Lower and am ready to snap that upper on.Oop's gotta get a Butt Stock ;)VulcanLower4.jpg

You'll need a faster twist rate to shoot those guys .... I'd think a 1-8 or 1-9

What we're saying is Bullets such as Varmint bullets have very thin jackets.With the faster twist rates like 1:7 put to fast of a Rotational speed on the bulletthus causing it to litterally seperate the jacket from the bullet in flight.Does not matter if it is a 40gr. or 55gr.A 40gr. will stabilize fine in a 1:7 if exiting at a low enough FPS, however heavier bullets like 60gr. and up need a faster twist to stabilize proper because of their longer lenght.Also short light bullets with thin jackets pushed to fast from a fast twist barrel stand the chanceof stripping through the lands and not being stabilized at all and the jacket coming apart before the bullet leave's the barrel, that is why the 22-250 and similar are slower twist rate's, generally 1:12 . That high of a rate of FPS in a slower twist rate than say a 1:12 would rip the jacket off the bullet before it left the barrel.69gr. Match bullets are great for accuracy and yes do require a faster twist to stabilize proper,Such as 1:7 - 1:8But they are not good for Varminting, to heavy. They do not fly very fast and they drop quick.And I don't think anyone makes a Varmint bullet in that weight as far as the .223 goes.

That 69 gr Matchking isn't intended for hunting ... I have some in 52 grain for my 1-14 twist 22-250.what is the twist rate of your barrel?

Those MatchKings will blow right though and will probably do little expanding.A better choice would be a Soft point in that weight.Also If its a 1:9 give some 55gr. V-Max a try

When I want something a bit heavier I sure like the 55gr V-MAX's in my Savage with 1 in 9 twist. They're very accurate, I'm sure Hylander will back me up on that. ;)

Very good call on the WOA Hylander ;) Im gonna use John H for my NM upper too. Spoke with him last week. Probably use him for the 204 upper if I go that way also. Can't wait to see it together, yours and mine both B) Good call on the slower twist for the varminter. The NM have a 1:7" so you can shoot the 80's and some will even shoot the 90's. Not as well as the 1:6.5" but only the high dollar barrel makers make those. Enjoy. Scott
