Rifle Build

Postby BGipson » Wed May 17, 2017 10:14 pm

The parts keep rolling in. I now have the rifle, Burris XTR Signature rings, Harris bipod, and a quick-detach Pole Cat bipod for sitting/kneeling shots. Now I just need to order the Vortex HST 6-24x50, muzzle brake and some brass. Already have the load mostly worked up (will need to put final tweaks with new brass) and have a 180gr Berger doing a touch over 3,000 fps. Pretty impressive for a 7mm Rem Mag. Danged budget keeps slowing me down.ImageImage
Every day I try to be the person my dog thinks I am. If I have accomplished this when my time comes, I feel I will have had a pretty good life.

This has been a gun I've wanted to build since I settled here in Wyoming. Something that lets me have the ability to shoot very accurate and carry energy to longer ranges so I can make clean, ethical shots where I need to.

When you get done with yours you can reconfigure mine.

GB I question the 180 gr bullet out of a 7 mag at 3000 fps ?
My son and I have been working on a Rem 7 mag with 168 gr bullets with 5" groups at 600 yds....His goal is 10" at 1000 yds !
He thinks he can out do my 6.5/284 with 139's ?

Hey my cousin and I are always down to work on rifles. What do you have and what are you wanting to do?

It has a hefty amount of recoil but we are getting about 3009fps average with H1000 and the Berger 180's. It's also shooting around .5 MOA which is just fine by me also. It is definitely an anomaly of a gun being able to produce those velocities without pressure signs but I'm gonna run with it and not ask too many questions [emoji38] that 6.5x284 is a sweet little cartridge! My cousin runs the .260 Ackley with the 140 Berger around 3100 (if I recall correctly). That's actually the rifle I shot my deer with this past fall at 975 yards.

I have a Remington 700. Would like to be able to hit things out to 1000, but need a gun comfortable to go 600 for sure.

That bullet weight is where the 7mm really starts to shine. It's amazing you can get those velocities with that bullet weight. Have you noticed much temperature sensitivity with the h1000? Something worked up at 20 degrees could blow primers at 70.

What caliber Gene? 7 mag? Or are you wanting to re-barrel it and start new?

Mug, if the 180 hadn't been something that worked, I would have dropped to the 168 but was glad the 180 was fine. I'll definitely be doing some temp sensitivity checks this summer but from what I've read/seen, it shouldn't be an issue. Wyoming is awful cold most of the time after all. Record high for my town is 97°.

Rem 7 mag. Don't mind rebarreling to make it happen. Right now it's all factory.

No that's a perfectly capable rifle. Just making sure it wasn't a .243 or .25-06 or something that wouldn't carry the energy out to range. We'll bed the rifle as a start, do some load development and see what we get.

GB back a few years ago a friend of mine wanted to shoot 180's out of his Rem 700 7 mag , he had to set the longer bullet back
into the case so far , he lost valuable case volume for the powder he needed to get any reasonable velocity so , he had it
"Long-Throuted" , which worked wonderfully as long as he didn't load more than 1 shell in the magazine . The magazine then
became to short with the 180's seated out for best performance . That would be my question to your buildup ?
Really there's not a better Caliber with SD or BC along with the Velocity the Rem 7 mag can produce and with today's Bullets
offered , they'll kill at any distance , a hunter can hit them at , if it's in a area of where they live ?
Long Yardage shooting takes trigger-time and Optics to be good at ! Besides.....Money :yes:

I'm good with that. I'll get a scope better suited for longer ranges for the 7 mag and put the existing scope on a new .17 HMR.

I've actually got the 180's seated nearly to the lands and still have room to spare in the magazine. This rifle has excellent mag length. As far as rifles go, when I re-barrel this gun eventually, it'll be a debate what caliber I go with. I wanted a larger caliber "hammer" I could use on anything in North America and not have to worry about it going far while also having the ability to stretch it out to range. .300 and 7mm are 2 great options for those pre-reqs with the 7 having less recoil and needing less powder.

Yep with the 7 mags case capacity being around 67 grains and the 300 mag around 80 grs there is a difference but not
in killing power only in recoil . The 300 you can go up in bullet weight , which is a big plus , if , you need it for animal size .
For North American game ( other than Brown Bears ) the 7 mag in the hands of someone that can shoot straight , with the
proper bullet weight , is really hard to beat ! Myself , I like my 338 Win with Nosler 210's for Elk and Deer and if I'm only
hunting Deer along with speed Goats my 6.5/284 takes up the slack nicely !
Come to think about it , I like ALL my rifles even my flat Bolts in 22-250 , they have done a nice job on meat whitetails
in the past with 55 gr Noslers with NO meat lost....hehee !
