I have a Remington 700 SPS .300 win mag, and i'm looking to get a Shilen barrel made, but i'm at a disadvantage of knowledge....

I want to become proficient at shooting at 1000 yard and I obviously decided I like the .300 winmag round, but as i read more and more i don't know what i should get for dimensions of the barrel.

I obviously want a heavy barrel, somewhere between 26-30in long (recommendations would be appreciated), and for shooting at 1000yrds what grain/twist should i get on the rifle for the recommended length? I really would like a 30inch because of increased accuracy but if you guys have reason to lead me in a different direction i'd love to hear about it.

Thanks for any help and i'm knew around here nice to meet ya'll

A longer barrel is not automatically more accurate. In fact within a given weight limit a short fat barrel is generally more accurate than a a skinnier longer barrel. A longer barrel in most cases yields slightly higher velocity .

I plan on getting a heavy barrel i was just seeing if getting a 30 inch barrel will dramatically increase that accuracy to 1000yards or would a shorter barrel do just fine? I was reading about grain and it seems a 160 grain .300 win mag has a higher velocity and a more level plane of flight for out to 750 yards so i would probably go with that grain due to the increased accuracy for this specific round. Although if my information is off i would appreciate any input from the community, and thanks Dick for your response. Much appreciated.

1/12 twist..maybe 1/13....bib 187 gr bullets...and 30 in bbl or so....the real issue if you plan on competing is weight...17lb class or up....

1:10" bore twist, 26" length. Don't rebarrel until you know you can shoot better than the rifle can with the barrel already installed on it.

If i were just wanting to target shoot at 1000yards not really hunting, but would like it to have good stopping power regardless at that range. I've read some people say 10' for a 165 grain, but all the random sites i read everyone has conflicting opinions

if you want to "hunt" at 1000yds...why not go to a long range hunting site...this is a TARGET/COMPETITION site.

Then that begs the question why you're here...............you don't do either, yet you remain?:confused: Seems the OP has as much right to be here as you do then doesn't it?

you act like a child, you respond like a child..
you add nothing to the thread, just attack a poster.
children do this when they have nothing to add to an event.
spoild children are the most common cause...
just continue your childish behavior....
it documents your lack of adult behavior....

..oh ya... your advise was sooo helpful wasn't it Mr. Live to Feud King of BRC.....
... you need to chill and smile more... instead of bringing all your frustrations to public forums

yes dumbie it was usefull...he has been given good info but in the end says he wants to shoot 160's for hunting...it dont fly in 1000yd comp does it ?
so if he wants hunting data for long range comp data will not work, will it >>>.
maybe you could try getting some one to read and explain the big words...
as you still have not added a single positive thing to the thread...
but who would expect more from a CHILD.
SO FAR YOU HAVE JUST REINFORCED WHAT I HAVE SAID.

may i suggest just the factory rifle forum and the maybe the 1000yd forum as a second.
i believe alinwa does long range hunting rifles..
this site is mainly precision competition shooting, not hunting...so you need to include hunting in your question.
data relative to long range hunting does not necessarily relate to long range competition shooting.

Mikey, I have you on ignore, but still know you are spewing BS. I wish there were a way to erase you from the forum completely.

It depends upon what weight of bullet that you want to shoot. A 12 twist will handle 168 gr bullets and anything smaller. An 11 twist will handle up to the 220 gr bullets. A 10 twist would be fine, but there's not much need to go to that twist unless you want to shoot over 220 gr bullets and maybe if you are shooting in a cold climate. Haven't seen the need for a 10 twist on a .300 in Texas where I am. Not sure how much over those bullet weights either twist the 12 or 11 will handle. As to contour, that again comes into how heavy a rifle you want. I build a lot of rifles with contours that match the Remington varmint contour if you want a rifle that's not going to be too heavy. It makes a rifle about the weight of a Remington varmint rifle. Or if you want a heavy rifle, then guys go with LV to HV contours or 1000 yard contours. The 1000 yard contour is about the same as a HV contour barrel except longer. The first thing I'd suggest doing though before you rebarrel it is to replace the SPS stock. They are junk. Put a McMillan, H-S or Manners stock on it with a good bedding job on any of those stocks with a fully freefloated barrel and see how your rifle shoots. A rifle with a McMillan A-5 stock with regular fill, full length HV taper barrel will weigh around 13 pounds before you put a scope on it. With a varmint stock and a varmint contour, the rifle will weigh around 10 pounds, don't remember whether that was with scope or not. My 7 STW weighs 10 1/2 pounds with HTG stock, 5.5 contour 27" barrel and Leupold 4.5-14x50 LR scope.

By the way, welcome to the board. As far as I'm concerned you asked your question on the correct board as that's what a lot of the gunsmiths on this particular forum do is build rifles. The only difference between a short range benchrest rifle and a long range rifle is the stock configuration, cartridge that it's chambered and most generally the length of the barrel. Other than that, they are assembled pretty much the same.
