I wanna duplicate this rifle
Gap 7wsm at 2000 yards - YouTube
Heres where i need advice since i cant get a hold of the shooter on the video.
Hes shooting 180 berger vld on a short action.is this round going fit on mag oal?
Hes barrel 1:8.75 bartlein 26" this twist is very hard to find i do see a lot of 1:9 twist.
I found 1:8.75 31" keiger what is the minimum i can cut this barrel?
Which of 1:9 bartlein 30" and 1:8.75 kreiger can serve the 180 vld better..
Ty SH
Ive been wanted to try 2k :)
 
The round will fit in the mags. You can also get the Alpha WSM Mags. They fit easily.
That barrel twist is easy to find, GA Precision stocks them.
26" is plenty of barrel length, I run 27" + a suppressor most of the time.

Good Luck

Does gap sell you barrel or you have to do your build trough them?

They might sell you just the barrel. But it would be worth it to have them do the build for you if you want that same quality and accuracy you saw in the video above.

Also, if looking for just a barrel: Try bugholes.com or go to Bartlein directly and place an order.

Bugholes has only 1:9 in twist no 1:8.75 i dont know how much different will make.i found a krieger 1.8:75 but its 31" what is the minimum i can cut it down to? Or should i call gap ask for moon and ask him to build me one..i wonder how much to build just barrel with trued action?with them suplying all parts
 
1:9 will be fine, If you have GA build it for you that's what they will use unless you spec something different.
Moon does not work at GA any longer, he has his own business a couple of block north of GA in North KC, MO

At the present time the biggest obstacle IMHO to this project would be a good source of brass in any large qty.
Although if it is a complete build, hopefully the supply of brass would loosen up by the time the rifle is complete.

Tnx jet il try call moon monday..by the way can what is the minimum i can cut a 31" barrel?
 
I PM'd him a while back when I did my load development of my 7wsm.

Having gone through the same decisions for my build. Here is what I went with:
- surgeon RSR action
- badger m5 DBM
- 28" Kreiger #17 1 in 8.5 twist
- melonited
- Alpha mags

Here is my load:
- 180gr Berger hybrid
- 64.5gr H1000
- velocity 2946 fps

I think Skyking has a Bighorn action.

I won't go with anything slower than a 1 in 8.7" personally if you are planning to shoot the 180grs which has an advantage over 168grs at further distances.

Longer the better for the barrel if weight and size is not a major concern. 28-30" would be ideal.

Tnx mate
I just got off the phonr with cory (skyking) he has rem sa action with bartlein 26.hows your group at 1k. Im buying krieger 31" ill cut it down to 28" twist at 1:8.75 by the who put your rifle together? Contour on your barrel?
 
Skyking was very helpful when I inquired about my 7wsm build. I veered off a bit from the build I discussed with him. I was going to go with the Big Horn but I ended up ordering a Surgeon. So far I have a Manners TF1 and a Bartlien 1/8.7 barrel in my safe and I'm just waiting on the action.

Well I would take you up on the offer but unfortunately my stock is inlet for the Surgeon action, besides I'd hate to deprive you of the anticipation and excitement of a long awaited order. 

I ordered the barrel direct from Bartlien (9 month wait). I was under the impression that Surgeon had actions ready to go but unfortunately after I got my barrel and stock, I learned I would have to wait another 8 months. It's a slow project but it should be worth it.
 
GA Precision built my 7wsm with a 26" Bartlein 1:8.7 twist. That's what George (the owner) recommended. I would have liked to have a little tighter neck, their reamer is 0.320 I believe. I don't mind turning case necks to clean up run out. I haven't taken mine out as far as skyking; my land has too many trees but its scary accurate out to 750yds. I missed an antelope last year in SE Colorado at 1,011yds but followed the trace go underneath his front shoulder. I shoot 65.8grs of H1000 but only get 2,880fps with Berger 180gr hunting VLD.

My contour is a #17 heavy varmint.

I don't usually shot for groups, but I would say that shooting 1000 yds at a chest-sized steel plate is boringly accurate. It doesn't really get interesting until I stretch it out pass 1600 yds.

I wasn't completely happy with the gunsmith that built that rifle, so I will refrain from telling you whom because I think he makes good rifles but just doesn't have the same attention to detail as some other gunsmiths.

I'm getting Mark Gordon from Short Action Customs to fix it and change the stock to folding one, etc.

I own several custom guns, but the gunsmiths that I've been most happy with are as follows in no particular order:
- Mark Gordon @ Short Action Customs
- Mike Bush @ BlackOps Precision
- GA Precision

Which Surgeon action are you getting. Short or long action? If short action, I would suggest getting Seekins or Alpha mags.

this the first time someone unhappy with GAPs job.im not geting any surgeon action im getting rem WSM action with kreiger 31" heavy varmint 1:8.75 ill cut it down to 28" (hopefully).ill be using aics chassis and planing to get accu mag 3.050 inside oal.my plan is to shoot it to 2k so is 28: barrel wil be ok?
 
Just to clarify, I am not unhappy with GAP. I have 4 of their rifles and been very happy with all of them, so much so that I will probably never sell them.

If you really want to get to 2000 yds supersonic, then your setup is cutting it close. I'm shooting at high altitude and have a fast barrel, so I just go subsonic at around 1950yds. But if you really want to shoot that far, I would go with a long action or larger caliber.

What cal would be good for the 2k? What would be a short action that capable to do it.im stil on the mision for that 2k.ty for help/advice mate

In a short action, 7wsm would be a good option. 7saum is a little more powder efficiency but brass is hard to find. For the speeds that you are looking to get to be able to reach 2000 yds supersonic, 7wsm is better option for larger case capacity vs. 7saum.

You can probably reach 2000 yds supersonic if you load them hot with CCI mag primers, but it will depend on your atmospherically conditions. So plug your numbers into a ballistic calculator and see. I would consider getting a faster twist (1 in 8.5" or faster) and longer barrel (e.g. 30") which will help to get a faster velocity and less drop when your bullet goes subsonic.

If you point your bullet tips with Whidden pointing die that will also give you about 3-5% higher BC depending on the bullet. Their website says 10% higher BC, but I think that is overly optimistic from what I've seen in my calibers.

Retumbo could work but your may not be able to stuff enough powder into case to get your desired speed. H1000 powder would be good option.

----------

If you aren't stuck on a short action, then I would go with a 300 Norma Mag with 230gr Berger OTMs personally for 2000yds shooting. It will be easier to shot hits/misses and will have further range than the 7mm magnums. Next real step up is 338lm, 375 Cheytac, 408 Cheytac, etc.

bjay, from your profile location you are in Hawaii? Where is Hawaii can you shoot out to 2000 yards? I have a hard time finding places to shoot that far even with Nevada having so much BLM open land.
