Suggestions for varmint rifle project

[308 nate]

huntem,
I will agree with all of those that mention the 6mmbr fast twist for varmints beyond 350yds.In fact the 6BR is one of my all time favorites.The 6br will easily hit 3800fps. in a 26" barrel with 55gr. Nosler BT's.....varmint vaporizer. and the 1 in 8 twist will hit 2900 - 3000 fps with 105...excellent for longer range.

Good brass is easy to get and there is a huge selection of 6 mm bullets,very efficient case and easy to load for.
other considerations, if you want something with a little more snort and a little different then you might think about these other options...

I have recently been shooting a .243wssm rouge .272 tight neck and all I can say is it is amazing.
115 D-TAC at 3175 makes for an awesome long range varmint rifle. My rifle is holding .5MOA at 1000 yds. and I actually shot a .3MOA group at 1000 yds. the other day. I have also shot 4 consecutive groups at 600 yds. holding .3MOA. As far a white tails the 115 D-TAC still has 1550 ft./lbs. of energy at 500 yds. and all this with just 47 grs. of powder. Here is a link to an article I wrote about shooting this cartridge to a mile. 1 mile 6mm The 105 A-maxe's in this cartridge will also be varmint vaporizers.

As far as the 6.5's take a look at the .260 and the .260 improved. The .260 is a real performer on white tails and with the right bullet is awesome for varmints.
FWIW and hope it all goes well with your rifle build.

And when you launch 115 grains at that speed you have a lot left at 1000yds. Of course your whitetails may be a little bit bigger than these little chihuahau sized deer that I shoot. At 1000yds you still have 775Ft# of energy which is deceptive because you have so much weight and sectional density that energy doesn't really mean much.

Another interesting point with the 115 gr ULDs is that every additional 100fps you can coax out of the barrel. you are rewarded with an additional 100yds of effective range.

When gas is $3.00 a gallon and I have to drive 1500 miles one way to hunt, I ain't in the least worried about blowing out the primer pockets on 10 to 20 pieces of brass. Right now I am losing nearly 10% of my brass per firing. But no antelope will be safe. All the little fawns better run and hide when they see my truck roll up. Come to think of it I may not remember what an antelope looks like so all the cattle better hide too. /ubbthreads/images/graemlins/grin.gif

We will have to play at a high level to beat Hawaii, not sure how we replaced some key players on defense and offense? Kinda think we will have a winning season just don't know how impressive it will be...Looking for good things out of John Parker Wilson and a good stable of running backs but you know as well as I great defenses=Championships. /ubbthreads/images/graemlins/wink.gif

Well the short version of a long story with many many variables, I have put the custom rifle on hold for a while.

But the itch still remains for a different rifle, so I have decided to look at the factory route with the intentions of possibly using this action down the road for the custom project. While I have multiple brands of guns, I still favor the remington action the best.

I believe I have narrowed the choice down the the 700P. My problem is now the decision between the .308 and 7mm Rem Mag. Which basically is SA versus LA?

I have a 300 Ultra so the Win Mag is not an option.

308 Nate,

Can you provide more info on the Rouge?
What case you use, case prep, ballistics, etc.

Thanks

shooter65,

The .243WSSM Rouge is a .243 Winchester Super Short Magnum improved 37 degrees with .009 body taper. Then the necks are turned to .270 for .272 reamer,then it is throated for 115-D-TAC's.


I'm using Winchester brass but I believe Federal also offers brass. My case prep involves sorting out cases by weight and keeping everything within 1 gr., reaming inside flash hole, reaming primer pocket,turning necks.


I have not messed around with many loads.
Here is the load I am using:
Winchester brass
Federal GM 210 primer
47 grs.of reloader 22
115 D-TAC's .005 into lands
muzzle velocity 3175 fps.

As far as B.C of the bullet my program didn't have the 115 D-TAC's so I entered the B.C of the 115 Berger which is .597 and it followed all the way out to 1 mile so the B.C is at least that of what Sierra states.Visable pressure basically non-existant,primers maybe starting to flatten by the edges,but is almost unoticable

The barrel is a Broughton 5C 1 in 7 twist and 31" in length. I believe you would see little to none velocity drop at 28" the barrel is long enough to reset and rechamber twice. As far as accuracy I am consistantly shooting .330 MOA out to 600 yds. off the bi-pod (in good conditions)and have shot .330MOA out to 1040 yds.

I hope this is the info you were looking for.Feel free to e-mail with anymore questions or respond here.

P.S froma 600 yd zero there is 12.5 MOA up to 1000

My thoughts.. get a 280 AI. Shoot 162 grain A-max at 3000fps.

The A-max has a BC of .625, and a plastic tip, wich will expand properly when hitting the varmint. The match bullets are really unstable.. sometimes they go straight through.

Should give 2500-3000 rounds down the barrel.

243 Win. 55 Nosler B.T. at 3,950. Look at the ballistics to 1,000 yards. Load up the 70 or 80 grain Nosler B.T if the wind is severe. I shoot coyotes at extreme range behind my house with the 55 Bal. tips and very terminal. For deer use the 95-100 Partition or 85 Barnes TSX. Very practical and inexpensive but effective. The ol'e 243 is still a very versatile round!

Might want to look @ the ballistics of the 105 Berger loaded to 2850-3000fps as well /ubbthreads/images/graemlins/wink.gif /ubbthreads/images/graemlins/wink.gif.

I dont think a 55g bullet is considered optimum for shooting to 1000 yards. I think the various VLD bullets in the 90-105g weight are 2x the bullet for 1000 yards.

 

[Takman]

What load are you using with those 162's, sounds interesting?

 

[biff's reloading]

ya the 55 isnt worth much past 500. its got a whopping 100 lbs at 1000 and its below mach

it also drops about 425" (i think the tip of the barrel would be blocking ur view in the scope /ubbthreads/images/graemlins/smile.gif )and drifts about 210".

Here is the data on the 243 load with the 55 grain BT. At 1,000 yards it is still going 1,389 FPS with 236 FP on energy with a 226 inch drop.
The 90 Grain Berger Match BT with a high BC does beat the 55 but not much. At 1000 Yards the velocity is 1389 FPS energy 236 fpds with a drop of 226.73. Obviously the wind drift is less with the bigger bullet and that is why I carry both bullets and they shoot very close from 100 to 1,000 yards.
The varmints I hunt don't take 1,000 Pounds of energy to kill. The 17HMR has 250 pounds of energy at muzzle! The 22 LR has 100 +_ depending on load. I hunt coyotes a lot and any bigger bullet has a tendancy to rip a gaping hole in the hide. Also the recoil of the little 55 doesn't beat you up as bad if you are shooting a few hundred rounds at a sitting. The recoil of 90-100 grainers really get you after a while.
