Thinking about a 6x45 build

[budlight]

I really thought about the 6X45. 223 is so much fun because it's cheap shooting. I already had quality 26 inch 243's. So it came down to cost and 6 X 45mm isn't something that I would take out PD hunting and do 300 rounds a day.

So I bought the Valkyrie upper match grade stainless. It is my long range squirrel gun.

These used to be about 10 cents each when you bought them by the thousands. I bought 5000 and they are about gone.

.224 RMR 69 Gr. BTHP 3GH *NEW* (Read Description Before Ordering) | RMR Bullets

We make this bullet ourselves. It is still in development so there may be some variances from lot to lot. We have pretty much gotten this bullet to where we want it. It is nearly perfect. I say nearly because city wastewater requirements mean we don’t currently have a way to polish/degrease this...

I got the 1:7 and 22 inches

The 6x45 is a really fun cartridge with a great history, but... I think a guy would be foolish not to look at the 6 MAX these days in an AR bang stick. The 6 MAX in performance kind of reminds me of the old 6mm Tomcat which was the .25 Tomcat before that, based on the .224 Weatherby Mag case, actually a very nice little cartridge as 6mm go. just my 0.2 Cheers

I have at least a dozen X caliber barrels, not a bad one in the bunch, and I expect very small groups, and super smooth barrel bores!

I had a 6x45 a few years ago. I wanted to shoot 105s. Never could get it to work the way I wanted. That was in a bolt gun. I still have the dies on the shelf. I got a 6ARC when that came out and I love that in a gas gun. That has gotten me thinking because I have a bucket of 223 brass. I'm not a big 223 fan, but I like 6mm. I looked at the 6MAX, but you can't make that from 223. However, the 6 mongoose in a gas gun is a project I'm looking at for this year. 223 brass, mags, bolt, but the ability to run up to 105s hpbts in a magpul mag.

Are the dies for sale?

Did you use 5.56 brass or 223rem? Just wondering if using the 5.56 you can get the extra max pressure difference between the to? That extra 7k in pressure really adds velocity.

I just used either pmc .223 or lapua brass in .223.

Thinking of an AR 6x45 build. I've got tons of LC brass, lots of 6mm bullets, powder..........
Plan is to just buy a barrel, I've got an upper ready for the build. Leaning towards an 18" and shoot 70gn and under bullets
Only thing I would need is the dies and mandrels to make the brass

Would like to hear your opinions

I shoot a 6*223 and it's a pleasure! Just run your LC brass through the dies load and shoot! Mine is a 24" match rifle. NRA high power.
