tell me 'bout the twist. I'm looking into a long range rifle capable of 1000yrds and keep seeing different twist rates in the barrels. I'm going to buy a Savage but am unsure of what caliber or configuration yet. Just want to make an educated decisions. Also, I know you should bed the stock, is the bedding in this stock the same thing only different?

Savage Arms 12FTR Precision Target Rifle Series

TIA,

Twist rate is dependent upon the caliber and the length of the bullet you're going to use. The longer the bullet, the more twist you need to stabilize the bullet. If you spin your bullet too fast, it could fly apart.

Typically with a .308 cal bullet you need approx a 1 in 10" twist. Longer barrels tend to need slightly less twist than shorter barrels to get the bullet spinning and stabilized. I'm sure someone here is more knowledgeable than me on the subject though.

Edit: as a side note, I'm currently working on a Savage 112 with a stainless fluted bull barrel and laminated bench rest stock in .30-06. It plans to be a 1000yd gun when I can break down and pay for the glass for it.

For a 1000 yd bolt gun i was looking at Remington's 700 XCR tactical in 300 winmag. it is a very well ballance rifle with super smooth action. and is about $1200.

I really am curious, where does one shoot 1000yds in the eastern half on TN?

That looks like it has all you need except glass. It is a free floated heavy barrel so you don’t need to worry about bedding.

I’m curious as to what you are going to put on that for glass. :)

I have what I think is a 1000 yard rifle. If you find a range we can walk on without being in a match let me know. :puke:

there are alot of variables as to what barrel twist shoots best in each caliber. the one i have more familiarization with is the Armys M24. its a 11.25" twist and was designed around shooting the 175gr SMK bullet. i have also shot a personal build in .308 that was a 1:12" twist and it did great with 168gr and 175gr bullets, as well as a couple M1As with 1:10" and 1:11" twists. they seem to do better with the 150-168gr bullets.

to effectively get out to 1K repeatedly, id suggest a 175gr bullet or a bit larger to get the stabilization out that far. i know there are others out there that can get out there with lighter bullets but i started seeing keyholing past 800 with 168s which i was told beforehand would probably happen by more experienced shooters.

I'm not a brand whore. Leuy is out. I have really liked the Bushnell lines. I might spring the $$$ for a 6500 but like the target turrets on the 3200. The 3200 is only a 10x.

When you have it all set up let me know. I would also like something that can hit at 1000yds without killing my bankbook. I was looking at the Panther™ LRT-SASS, but it is a bit pricey.

That twist calculator is the answer you want. Its not bullet length that is the important factor as some one said. Its the weight of the bullet. For example, Berger bullets are longer than "normal" bullets of the same weight. Its the shape that makes them different (VLD). Barrel length has little to nothing to do with twist selection. Length does deal with velocity gains/loss and of course over all rifle weight.

As for bedding......I have been using dev-con for the action bedding. Harder than glass. More durable than glass. Easier to apply to stock and clean up as well. Brownells has it. Might cost around $40.

But with the triple pillar bedding on this Savage, do I need to do that too??

Wrong. it is the length and the sectional density of the bullet.

Good luck. You might get it to stay i the 10 ring. It will need to be at least 1/2 MOA.. and you hold will need to be half of that.

Tullahoma at the National Guard Training Center next Arnold Air Force Base.. but good luck.. they have a new CO.. and he is a prick and don't want civilians shooting on the range.

The other is Oak Ridge at the Oak Ridge Sportsmans Assc. Membership is 120.00 annually.. prorated. There are memebers from all over the country that belong.. why.. it is one of the premium 1000 yard ranges in the country.. and one of the hardest to shoot.. but then so is Camp Perry.

I want to head to Oak Ridge when I get a little better with the bolt gun...

Froggy is there a guest rate per visit? Or is it members only?

The BC (ballistic Coficiant) is what determines good bullets from the not so good.. the BC on the Sierra 168's is .450 which is the same as the Sierra 155 palma bullet. The 155's must be going no more than 2850 to make 1000 yards.. but 2950 is the zone for that bullet.. twist 14, 13 or 12. My palma gun is a 12 twist 31.5 inches long. I shoot a Berger 185BT at just over 2850fps.

So the 168's are a has been bullet from an era gone by.. there are better bullets these days to use.. so now you know why the 168's keyhole, they are not going fast enough, unless shot in a 06 or 300 mag something or other.

I agree.. that if you have a 26 inch barrel.. the smallest bullet to consider is the 175 gr ilk. Tangent ogive (Boatails) bullets are easier to get shooting than secant ogive bullets (VLD's).

M1As with 1:10" and 1:11" twists. they seem to do better with the 150-168gr bullets.
That class weight of bullet is fine in the M1A at less than 400 yards.. after that.. 175's.. if you want to shoot the M1A at a 1000, min 175's.. but you would be better off with 180's or 185's. Oh.. and make sure that you have lots of op-rods handy and extra bolts..

What ever scope that you use.. make sure that it lots of elevation and windage.. also.. you will need a extended scope rail.. if you don't.. when you lay down behind the rifle.. your eye will be too close to the scope.. and you will find yourself pushing away from it.. not a good thing to be doing..

Actually the best scope out there right now for long range shooting is the

Sightron SIII 6-24X50 LR D.. about 760.00 dollars or so.. depending on the vender. It has the same clarity of a Nightforce, 100 moa elevation and 100 moa of windage..

and what is best.. it is half the cost of a Nightforce. You may not be a brand whore.. but I think that you may want to go back do more reasearch... may i suggest reading all you can read.. on 6mmBR.com those guys have done a lot of testing.. and they don't BS over there either.. some of the stuff that goes on on this site.. ain't tolerated over there.. so it is an excellent site for good info.

Get yourself a Savage F/TR or Palma Rifle and shoot something that is more accurate than that!

You can have a bedding block and use the middle screw to attach the recoil lug.. this is how it is done with the Barnard Action.. that way.. you don't have to have a recoil lug on the front of the action.. makes it easier to switch barrel the thing.. oh.. yeah.. they are easy to switch barrels on..
