5 for 5 with 6x45

[Longshotjames]

Trying to make end of year harvest quotas

dense fog kept the Longrange game shut down so the 6x45 went to work.
Using 80gr Speer Hotcore out of my Dtech 20" Shilen barrel @ 2800fps

5 shots 5 kills ....1 head shot, 1 neck shot and 3 identical just behind the shoulder.

time to bacon & jalapeño wrap more tenderloin!

^all pass through shots

dinner at your house. my mouth is watering.
I finally decided on the 6TCU parts ordered now the wait

My 6x45s are great, but , my 6TCU AR is Awesome ! Both are killers beyond their size.

I like the idea of the 6x45, always wanted to try one. I wanted a 6mm AR for a long time, but never did seem to happen. I ended up with a 6.8SPC which I've grown fond of.

I haven't really heard of the 6TCU, back when I was considering a small frame 6mm I was looking at the 6mmAR and Turbo40 version.

Looks good. Meat from the original package can't be beat.

I am a 6-223/6TCU nut. It does way over what one would think. I have a few hundred of the old Hotcor Speers laid back myself. Curious if anyone has compared them to the "new" gold dot offering.
The raves about the 6ARC/Grendel, like it is new. I just can't believe folks never gave the 6-223 and variations a try. One of the easiest wildcats I have played with.

The appeal for me moving up to a 6mm is you have to run at least a 6mm bore for deer hunting here in WV. Plus I want to build an economical rifle for my son to practice with and hunt with too.

I originally planned to build a 6mm on an AR but I recently came into a 223 bolt face action that I would like to use instead. I'm thinking the 6x45 would be perfect because it's simple to make brass for, plus I have plenty of quality 223 brass on hand. It's low recoil and has a great bullet selection in 6mm. So I'm starting to lean towards the 6x45 for building him a trainer/hunting rig.

For you guys that are running the 6x45, does this cartridge benefit from a longer barrel velocity wise? I don't want the rifle to be too unwieldy, I'm thinking a 20-22" barrel. Also, I'm assuming this cartridge shines with bullets on lighter end of the 6mm spectrum? Got any twist rate recommendations?

 

[Liberator]

In my opinion , 20-22 in. barrel is perfect. Most of mine [ 6x45s and 6TCU ] are 1-10 twist and handle 85 grainers and below real well. You'll love it. Can't understand why it's not a factory round. Is a great deer round for those states 6mm and above.

I'm jumping onto the 6/45 bandwagon. Not sure in what aspect (bolt or Ar) but it will be happening.

 

[lepcur1748]

What is the real velocity gain to go to a 6 ARC? Seems like 6 45 would be easier.

20" is about right for the 6x45 to balance length & velocity. 1:10twist will allow to run anything 100gr and under. It's recommended for 80-90gr

Is there a downside to running an 8 twist in a 6/45? I don't plan on running anything bigger than 90 at this point.

Can you Over twist? In a 6mm the 1:10twist is right for 100gr. Maybe some one that knows about twist rates can chime in about Over twisting and the effects on stability And expansion?
