F-Class Bolt Gun for Flo

[Rocketvapor]

Collecting parts for a 22 Nosgar bolt gun for Flo.
Have Savage 10 receiver with Accutrigger. 
It's a push feed, short action, with mag and aluminum bottom metal and a .308 sized bolt head. 
Bought a PTG 6.8 bolt head (stripped) for the Nosgar brass and a .223 bolt head for 22 Nosler brass.

Bought a used .243 barrel, 1:9.5, 22" for $77 just to have something to shoot (once the stock comes in) while we wait on a Shilen 22 Nosler 28" SS bull barrel.  Have sent in dummy rounds for them to set chamber.

She picked a colorful laminated stock and that's gonna be 6 weeks out. 
Stock will be single feed with a sled.

I'll post as we progress to practice with the 243, and someday in the future with the 22 Nosgar. 



Our latest scopes have 34mm tubes.  I need to get a 34mm zero MOA mount, or rings. 
Receiver has a 20 MOA rail and I doubt we will need a total of 40 MOA.
The 1.45" high mounts might be a little high.  Somewhere I have a cheaper scope with 1" 30mm rings to check height once the stock comes in.

Are your matches at your local range or do you guys have to travel some for them?

[Rocketvapor]

Takes about 45 minutes to get to the 600Yd matches in Bogalusa.
Once we (or one of us) Masters 600 F-Open we will make the 2 hour trip to Pascagoula for 1000.
Either one requires being on the road before the butt-crack of dawn. 
Who knows, maybe we'll travel a little next spring/summer.

[Onepoint]

Thats not nothing. I get so spoiled in not having to go anywhere, but I am not shooting matches either.

Is that what the 22 Nosler is based on, the 6.8spc case?

[Rocketvapor]

Not really.
Some writters get it wrong
"The closest design out there is the 6.8 Rem SPC — that has been lengthened, necked down to 22 caliber, given a 30-degree shoulder, and had the rim rebated to 0.378 inch."

The parent is actually the .30 Remington (the 6.8 parent) but with a rebated rim.   

The 22 Nosler has a rebated rim (.223 size).
The 22 NOSGAR (Nosler/Hagar) uses the 6mm Hagar, necked down and uses the 6.8SPC/224Valkyrie size bolt. 
Hagar on the left.

Why the nosgar again? Just wanted to reuse the same dies and components? Short of running .223 or .308 in TR, you're open to 8mm and smaller. 6-7mms are pretty much the rage in f class of all ranges. The further out you shoot the larger the case capacity typically. Short ranges still see magnum cases for less drift.

[Rocketvapor]

I agree the 22 Nosler is a challenge when going up against larger cartridges.
I guess in the lower recoiling range the 6mm like the 6BR, 6BRA, are an option.
Maybe the 6GT or even the 6ARC.
A 22BR/BRA/BRX would be an option with even a little more velocity than the Nosler.
That would still make use of my supply of heavy 224 bullets. 

Powder charges of 30 to 32 grains, bullets from 80 to 90 grains, velocities fast enough to register on a 1000yd E-Target, a rifle in the 20 pound range, recoil with the 22N is nill, in an AR or a bolt gun.

Even if I didn't have a boatload of stuff for the 22N I don't see us shooting anything with anywhere close to the recoil of a .308, for 70 rounds in an hour or so. 
I'll have all 3 normal size bolt heads, and would only need a barrel to shoot something different once she wears out the big ol chunk of metal on order
28" bull Shilen select match. 
Looks like we will be into this for about $1500 (less optic) when all is done.
Guess we could have just gone to one of those big box stores (that sell Liberty safes) and bought a complete rifle in a popular caliber.

How would the recoil fare in .308 in say 110-125 gr. projectiles? Jus throwing stuff out there.

[Rocketvapor]

Recoil is "somewhat" related to the mass of the projectile plus charge mass times projectile velocity.
Look up recoil impulses for rifles.

Typical recoil:
https://backfire.tv/recoil/

For 100 to 300 yard shooting, light for caliber bullets will "kick" less.
The problem I see with light for caliber bullets is performance @ 600 to 1000yds.
For F-Class shooting, you can not use a brake, but heavier guns are common.

Just for fun I loaded up some .30-06 rounds for the Springfield with 100gr 30 carbine bullets. 

One of these days I need to get back out with the SKS.  Just have tunnel vision @600yds for now.   
Anyone remember the Survivor Shoots?

[Filroy77]

I made some of those 06 100gr as well. Have yet to try them.

Use the 155gr Palmas. Nice BC, light recoil, better performance than 168s past 500ish yards. They're pretty undersung for .308 pills.

[Danjal]

RV, recoil is kinda negligible with a 20# rifle.  Even with a 17# rifle running 125gr@3000 fps it'll recoil the same as fully kitted AR.

OK, give us some numbers on the 155gr Palma, ?
B.C.
24" to 26" barrel, velocity @ 1000Yards
many use Varget I guess.
Recoil with a 20 18 pound F-T/R rifle, 155gr projectile,  44gr powder, 2950fps?
I'm assuming it would still be supersonic @ 1000, where the 125gr probably would not.

I could easily pick up a barrel for .308 for Flo, and F-T/R @ 600 then 1000.
Or maybe a 6.5 Creed?

[Rocketvapor]

One thing we don't want to do is get too deep in trying to compete with the good shooters. 
We are trying to get better, but I don't expect to outshoot some of the old guys that show up with super custom (expensive) rifles. 
Some of the F-Class matches allow some Bench rest shooters separated to one side of the range, with breaks and cartridges that make the 22N look tiny

We even get a halfway decent 223 service rifle shooter that lives close by.
Sometimes with a long barrel 223 with open sights, he had a 599 last year, really unusual.
It's only 600yds, 
Between relays we switch the display over to watch his score. 
He shoots with the AMU.  Probably can be found on the interweb. 
Our goal is to out shoot, head to head, SFC Brandon Green (yup, sure, right ).

24" for 2850fps (depends on powder and case). All G1 here - Amaxes are getting .435, ELD match .405, Berger VLD .464, Berger fullbore .473, Berger hybrid .478, Lapua scenar .460

Warner is the king of BC, but expect to pay. .589 BC G1. Sierra claims to get over .500 on a couple of their offerings, but from tests, they were more in line with the rest at about mid .4's.

Starting new look into 6.5's and 6mms. 6.5's can make .7 BC and 2900 FPS, while the 6mm can run .55 for heavies (100gr or more) at about 3500 FPS, just watch 6mm availability. They were getting sold out fast for a while, no clue if it ever got cleared up or not.

We currently have a boon of long range bullets and cartridges. It's all about what you want to run really.

FYI the .308 was directed at Filroy as he brought it up. I ditched the .308 for LR and stepped up to 300 win mag running 225gr. Once I run all these out I'll probably try the newer 250's. .878 BC @2700 fps. They're supposed to almost make 2100yd before sub. My current 225's are at about 1800ish till sub.
