Cartridge selection

[1shot]

I'm planning a P'dog hunt next year with an old friend that moved out west, while leaving me stuck in Ohio. I would like advice on some specific cartridges, nothing exotic, just with-in the boundaries below. The parameters are as follows:
1. Must be in 6mm
2. Lapua brass produced and available
3.When naming your favorite cartridge, please recommend a free bore for 105 JLK's.
4. Please keep it simple, and yes I will be neck turning.
5. I already have two 243 AI's that we all know are throat-eaters so I'd like to hear some opinions or if you already have a rifle that fits the above parameters, I'd love to here from you.
6. I have receivers in small and med. bolt faces if that limits you advice.
Thanks for your help,
Lloyd

Unless you plan to neck up, or down, you are limited to (Lapua) either 6BR or 243 brass.

I'm sorry I wasn't clear enough on my specs. Necking up or down is fine as well as false shoulders and bumping shoulders angles or neck length.

 

[waterfwlr]

12 twist 6br. Many varmint bullets up to 87gr vmax to shoot.

 

[NorCalMikie]

Why bother necking up or down? Go with a 6 BR and be done with it. Zero freebore and a no turn neck will get you the accuracy you'll have a hard time believing. Go with a 8 twist and short throat. Start with bullets in the 50 grain range and go up in weight as the throat wears. And it will over time, probably sooner than you would expect.
Load new brass and go shooting. Are you stuck on 105 JLKs? You shooting deer or P dogs? If your barrel is throated for 105s, you've got no where else to go when the throat wears except a new barrel.

How about the 6.5 x 47 Lapua? Necked down to 6mm, you've got the advantages of Lapua brass, and any chamber/throat configuration you want in a custom barrel.

Not a throat burner, and easy necking down to 6mm........

 

[JohnHenry]

Think a little smaller. 6mm-223Rem (6X45).

 

[Phil]

Think a little smaller. 6mm-223Rem (6X45).

Or even better 6-223AI (6TCU)......

 

[potatoe]

10t 6BR

 

[5spd]

6x45 & or my 6x6.8 is what I use out here when Im not running the .223.
No issues from 50-800+ yards.
No reason to run 70-105g bullets & larger cased caliber for p-dogs, but you build what you want of course.
My 6x45 with 55g NBT & 65g vmax does it so very well & with little recoil & burnt powder.
My new 6x6.8 build does the same.
Like others stated on top of the above, 6br, 6TCU, 6mm Grendel
Ive dumped my heavy varmint barrels for the light varmint barrels and still shoot the long strings of 10-30 in a row or more in a virgin area.

 

[TheOtherZilla]

Just curious why 6mm?? I live in the middle of p-dawg country and have killed tons using nothing but a 22 LR.. 22 center fires are also great.. . Anyhow why 6mm? I am curious.

 

[Sniper338]

Sounds like your screaming 6br to me too for what you want if it's a 6mm - 8 twist for 105s




Personally I'd do a 22-250AI or 22br for 60 to 64gr bullets!.... That's what I did!

 

[markT]

Savage Model 12. Precision Target Action: 6 BR / 8 twist.. 87 gr Vmax. N135, Lapua Brass.. Redding Competition Dies.. "Show Dog Producer." you will be very happy..

 

[savagedasher]

6 X 223 or 6 X 223 AI 1-14 Twist around a 55 gr bullet . Low recoil Not excessive barrel heat .Speed enough for exciting impact. That would be my choice. Larry

 

[savagedasher]

6 x45 (6-223 is the same. 24'' barrel with 55 gr bullets 3300 to 3400 FPS. EXCITEMENT on steroids Larry

 

[stacy]

22BR 12TWIST NEVER LOOK BACK LOVE MINE!!!!!!!!!

 

[fredo]

I've shot p-dogs side by side with my .20TAC (39Bkings) and 6x45 (70Bkings). The .20TAC had it all over the 6x45 in flat trajectory and wind cheatin', but it'd run hot after a string of fire. Whereas, the 6x45 is like the dang Energizer bunny on a p-dog town...just keeps going, and going, and going, and going, and going, and going, and going, and going.

And going, and going, and going...


Sure a 6BR would be badazz! But for economical fun & longevity, its tough to beat the 6x45 on a ~25gr powder burn. I used mostly LC brass & AA2015 for p-doggin', and didn't feel slighted.

Gonna feed my new 1:8tw 6x45AI Lapua brass. Chamber has .050" freebore for up to 95VLDs without cutting the legs off runnin' a lighter bullet. An 87Vmax is in the lands @ 2.385 right now, nice compromise. Dunno what a 105JLK would like, 95gr is the heaviest I'm caring to throw...

Have fun, whatever you decide!

1. Must be in 6mm 6 BR
2. Lapua brass produced and available6 BR
3.When naming your favorite cartridge, please recommend a free bore for 105 JLK's. Something around .100 for the 105 class bullets, if you decide to shoot lighter bullets I would suggest .025-.055 depending on what bullet you want to shoot
4. Please keep it simple, and yes I will be neck turning. Cannot get any easier if you choose this cartridge. Easy to load for and if you are shooting prairie dogs then there is no reason to neck turn.
5. I already have two 243 AI's that we all know are throat-eaters so I'd like to hear some opinions or if you already have a rifle that fits the above parameters, I'd love to here from you.I have a 6 BR with minimal free bore built specifically for a mid-range varmint slayer. Most accurate rifle I own, Shoots 65 grain V-max's just over a 1/2" at 400 yards.
6. I have receivers in small and med. bolt faces if that limits you advice.No limitations with what you have

 

[searcher]

The 105's are at a great enough disadvantage to the 70-90 options IMO (in a 6BR or similar), I'd not go with a twist or throating optimized for that bullet. That said, the 6BR does meet all the parameters of what you asked.

This was a eye opener for me. I ordered a reamer and dies to make a 6-45. What a great cartridge for youth and woman to shoot. The 300 black out doesn't work well for hunting. Bullet doesn't expand. 6-45 with 80 Gr Barnes will. Larry
