I have a 14" twist 6mm barrel that I can't seem to sell. It is unchambered.
What round can I chamber this barrel for that will work good with 75gr and lighter bullets? I'll make it a PD gun good to 600 yds.

simple......6BR.......run 55's Nosler BTs......65 V max....

easy 600 yd p/dog gun....H4895...Benchmark....IMR8208

Lapua brass......Rem 7.5's

6ppc might be another common cartridge for the light weight bullets. Personally I Would prefer a faster twist as I have consistently preferred the Heavier Bullet.

200 yards and in a lot of guys prefer the lighter bullets that will stabilize well in that slow twist barrel. Will do very well on targets and Varmints.

6mm Grendel on a Howa Mini or a CZ 527 action would sound interesting.

6mmBR!

More info here
Check out the "varmint pages" at their site as well.

6x47 Lapua with zero freebore will be outstanding with your barrel along with a 6 Dasher.

I have had 14T in 6BR, 6 BRX, 243, 6 Rem, and 6 Rem AI

thought 6PPC brass would be a prob......

guess not....Norma in stock at Midway.....

my Pac Nor 6BR barrel was built in '02......

has 10K++ rds out....12 twist...still a dog killin' SOB..

Most 6 PPC brass is made from Lapua 220 Russian brass. If I recall correctly Lapua tried making 6 ppc brass once but all the benchrest guys kept demanding the 220 russian so they could form their own, they like the stuff they made themselves better than Lapua's factory stuff. I'd guess 99% of all the lapua 220 russian brass gets made into 6 ppc.

still tough to beat the ole 6BR.......

Lapua brass....good dies.......rock on....

Cowboybart,

I use my 1-14 twist 6mm PPC benchrest rifle for prairie dog shooting occasionally, using 55-grain Ballistic Tips at 3600 fps or 65-grain hollow-points at 3400 (it has a 25-1/2" barrel). Haven't tried to shoot any at 600 though it works fine at 500. But if building one specifically for your purposes would do a 6mm BR instead, for the convenience of the .473" case head and a little more zip.

Thanx guys. I was leaning toward the PPC, but I'll have to look closely at the BR. I'm a little familiar with the 7BR made from shortened and reworked 308 brass. Is there sources for already made BR brass now or is it a cut, trim ream, form, fireform process still?
The barrel is threaded for a Savage small shank so that is the action I will be using. I'll have to look up the 6 Grendel and Dasher.

Any love for a 6-250 Savage?

Lapua 6BR brass ready to go.....you'll find the .308 Savage bolt face

much easier than a PPC .445" face...BR is std .473" 308

30-31 grs of powder.....6/250 Savage...? or 6XC ?

bigger appetite for powder...37-39 gr charge...been there done that

p/dogs aren't tough to kill.....6BR all the way.....

The 6BR is a great round for prairie dogs, I use one on a savage myself. Just be aware that it's a beaotch to get to feed, mine is used as a single shot. If magazine feeding is a requirement then think of something else. If you don't care about magazine feeding (I didn't) then 6br all the way. Lapua brass is readily available and ready to go out of the box.

never gave 'feeding' a thought......

my 6BR along with others uses Salvage solid bottom s/shots

Remove ejectors too...don't have to chase brass.......

Target actions work very well.......

MD- mind sharing loads for that PPC? I just got one(a Sako) and I'm looking to get some loads up and running in the next week.

Also, what scope do you run on yours? I'm thinking this would be a helluva PD rifle.

I'm using Benchmark in both loads, but a little more than Hodgdon lists, because my rifle has a little longer than standard throat. But a bunch of other powders work well too, including Accurate LT-32. I run Benchmark when shooting varmints, however, because I have a bunch of it obtained when it was a lot cheaper than LT-32!

The scope is a Bushnell 4.5-30x 6500 Elite in Talley steel rings.

Depends on whether you want stupid / simple / easy or whether you want to be creative.

For simple, go with a SAAMI minimum -spec'ed .243.

Next options, 6mm BR (I never could get one to feed though) or 6x.250 (use .22-250, not .250 savage, brass).

My favorite is the 6x.284. I had a 700 short action with the chamber cut with a custom reamer spec'ed out for a 60 grain Sierra seated with the base flush with the bottom of the neck of a necked down Lapua 6.5x.284 case. A local guy bought the reamer then let the gunsmith chamber rifles for several of us with it. I tried the 55, 70, and 80 grain ballistic tips and 58, 65, and 75 grain VMAXes. The 80 didn't stabilize in my gun. The other bullets were ok but the 70 grain ballistic tip with RL 19 was the most accurate (57 or 58 grains, I forget which now). Not bug holes but good enough for ground squirrels to 400+ yards. Inside 150 yards it was hard to tell hits from misses because there wasn't even spray within a reasonable search distance. One time I thought I was missing. After the 7th or 8th shot I noticed a stringer of guts hanging from a branch about 30 feet up a tree.

I also had a 6mm Rem AI for a while. That one was a problem gun. It would only shoot accurately with Win 760 and I got some weird pressure problems. Load 50 rounds. Didn't matter how many I shot at the range, none to 40, no problems, but when I got up in the woods I'd get 3 shots normal, 4 sticky, 5th would blow the primer, and I'm not crazy enough to light off a 6th, I'd quit and go home to clean it. So .. not a real fan. Maybe a different gun would work better but I hate making the same mistake twice.

If I were doing it and the barrel is at least 26 inches it'd be a 6x.284. Redding dies, Lapua 6.5-.284 brass, RL 19 powder, 70 grain ballistic tips.

I've got an 8" twist 6-284 on a 98 action and have the parts for a 10" twist 6 Rem AI - just haven't got the barrel threaded and chambered yet. Because this is a slow twist I am thinking small case. Maybe my thinking is goofed up, but that's the way I think. I would say 6-250 would be the largest case I would consider. Leaning hard toward the Dasher, just gotta get past the non feed hurdle in a repeater.

My 6 XC, with 30" barrel:

39g of R#17
105 A max
3170 fps
tiny, tiny groups, sub 1/4"

X Caliber never copper fouls, even at this speed!

A 6 Dasher or 6 BRX are wicked when it comes to groups, 105's at 2950-3000 Max.
