Tell me your thoughts/experiences with the 6XC

[Grumpystilskin]

Evening to All,
I’m a 243 Win guy. Just wondering if there any advantages or disadvantages over 6 Creedmoor and 243 Win. I’m fully vested in 243 Win for reloading, components etc.
I have a wandering eye so to speak.
Thanks, Tom

The selling point of XC to me is cheap Peterson brass and a little less overbore than 243/6 CM. But it’s hardly any different in capacity than the small capacity 6cm Peterson brass. Never had one.

I am waiting on a Criterion 6xc prefit barrel I have on order so can't tell you any experiences. I can tell you my thoughts on why I went with it though... Tubb sells peterson brass for $70/100, the barrel was $350 vs $450 for 6cm, and it should get slightly better barrel life than 6cm. So pretty much me being cheap.

This will be replacing a 243 win barrel. The main advantage for me is that my 243 is the standard 1:10 twist rate and cant stabilize the high BC bullets. The secondary advantage I hope to gain is a bit more accuracy. The best the factory 243 barrel can do with handloads is 1 moa for 5 shots, I'd like to do better even though 1 moa is good enough for the targets and distances I shoot.

If you have a fast twist 243 I would shoot that out first before thinking about rebarreling to something else.

I have 3x 6XC’s (as well as a lot of 243’s and 6cm’s). Performance wise (MV) the XC, 6cm, and 243win are same/same functionally.

The 6XC is like a bigger 6BR- not fussy at all, shoots everything, very predictable and consistent. I personally think it is the best overall package for that size 6mm cartridge.

Perhaps worth noting that Blaser offers rifles chambered in 6XC.

What’s the overall length of 6XC with the 107’s and 116’s loaded optimally?

2.760” ish.

Is the 6XC that much better than the 6mm ARC/243/6CM to build a new rifle for the cartridge if you already have rifles chambered in the other 3 cartridges? I would buy a barrel and get some ammo/brass/dies from David Tubb if it truly is as he has ammo and brass at good prices for premium components.

I had a good friend with one years ago in a stiller custom. I loved it so i bought dies and 200 brass pieces but haven't got around to putting one together yet unfortunately.

What do you think the best twist rate is for one? Is it worth it still with an 8 or is 7.5-7 preferable?

Com’on man! I buy dies/brass/bullets before the rifle too as a way to motivate me to take the plunge. Build you that rifle!

FWIW the SAAMI spec for 6mm GT is 1:7.5"

Does this case design lend itself to any feeding issues?

Thinking about swapping over to this after my 243 barrel is toast. Just for the shorter OAL with longer bullets. Given my M70 SA internal mag box allows only up to about 2.830”ish OAL

I wouldn’t replace good rifles in the other 6mm’s to get a 6XC.

1:7” or 1:7.5”.

Not in the ones I’ve seen. All are either AICS, Tikka T3, or M595 mags. They all feed like they should.
