Another cartridge question.

[David Milisock]

A very similar topic is being discussed,
Want to build a short-mid range rifle.
Do i want a
6.5 TCU
6.5 Grendel
6.5x 47 lapua.
I think the ability to use 223 brass is an important aspect i like.
6.5 TCU case capacity about 28gr.
The 6.5 grendel is what i want, with a 35gr case capacity, and the ability to pick up factory ammo.
As i said i have a 6br with a 39gr case capacity making the grendel redundant.
But a 6.5x 47 Lapua at 48 gr case capacity should be pushing the velocity in a nice node for 6.5 bullets. Perhaps better then the grendel?

This will be a little target/ hunting set up
As ive mentioned i really enoyj have a reduced power cartridge to shoot with is big brother.
223 rem-221 fb
17 rem-17fb
6.5 creed- ?
See where im heading..is it a wast of time and money..just keep shooting the creedmore.
Im looking for reduced power 6.5 creedmore with enough velocity im not wasting bullets on sub-par target performance. (50-200yrds)
What do i want to do?
Some cartridge are better off the starting line, some need distance to show their true colors.
Also shooting 50-200yrds do i want 6R, 5R, 3R rifling. ?

Some times this stuff is so confusing when you look at it to long , good judgment can fly right out the window..i have very little of in the first place.
The forum has been a blessing over the years in this aspect.
Thanks all

Have you ever thought that you're over thinking this?

There is another small case capacity option is the 6.8 SPC case blown out with a 40 degree shoulder necked to 6 or 6.5. The 6 handles 100s up to 3,000+ fps in an AR mag and a 16" bbl. It is the 240 Varmint. There is also a 6.5mm, the 6.5 GPC.
The easy one is the 30x39, with barrels in 308 1-10 chambered for the 7.62x39 by SOSTA Arms for $120 load them up with 150s at 3,200 fps and go to town 0-300 you got it in an AR. Use a 7.62x39 bolt and mags. Bonus is you can shoot military 7.62x39 through it, if need be.
