Remington 700P in 300WM- A review, build and evaluation.

[freedomintheskies]

Since the original rings were too high, I picked up a set of Vortex Pro Series rings.

They are a well made and finished ring and have their torque spec etched right on them. Nice touch! The finish is phosphate and matches the rifle and scope perfectly.

Had the rifle out to the range today to try out some hand loads too.

THe loads were Hornady208 ELD-M and 210gr Nosler RDF.


THe RDF's shot quite well with the lightest load of 4831SC I tried (See the picture below- 300 yds ) and then maintained a 2" group at 300yds. Time was short, so I didn't get the opportunity to shoot all the 210 RDF's. so I will continue it later.

very interesting build, reports and feedback. will follow on the leupold and long run use.

I'm not sure where you saw that someone won the PRS Finale with a Leupy LRP but I'm almost 100% sure that's not the case. Not a slight on Leupold (I have 2 Mk5 HDs) or that particular scope (of which I've heard good things) but I'd double check your info. Otherwise, interesting to watch the progression of your rifle.

Have you practiced off any barricades yet with a shooting bag? I have a fairly heavy .308 and the recoil, with a Heathen brake, which often has RO's mentioning the concussion of the brake is quite fierce (which means it does its job well), the recoil is still too much to spot my hits. Well, I'm working on recoil management with it. That said, I really have to hold the rifle, which introduces more wobble into the scope off barricades and bags; I would prefer a lighter hold, as the reticle doesn't wobble so much (maybe someone has advice for me, but I am sure that with a 6mm, I'll be on the right track). I don't know how well you'll be able to spot your hits with the 300wm. Shooting stages where I cannot see where my hits are has put me in the middle of the pack for competitions. If you cannot see your hits, you will not do well. As I have learned the hard way.

And of course, as others had chimed in, that's if you are allowed to shoot it at the matches. That said, I have a 6mm barrel on the way.

Also, the BC on the 190's and lower isn't all that great. 210's and above is where you get the benefit for the 300wm. Also, I had an LR 300wm rig. It shot phenomenally. All of my loads were just below max, and with Hornady brass, I blew out my primer pockets. My brass was only good for about 3 firings. I didn't have any other pressure signs. Just after a while I couldn't get primers to stick in the pocket. That said, I have my own parts list ready for my 300wm or 7mm RM long-range hunting rig. But for weight, I am going to go with a carbon fiber barrel. My goal is a 7.5lb rifle. I am thinking of going with the Big Horn TL3 Action. Lots of flexibility with pre-fit Savage barrels, swappable bolt heads and etc. I am just on the fence on whether I want a long-action or short action. Short action, I could go with the 300wsm, then swap the bolt head and have a .308 sized bolt face for whatever other caliber that I'd like to use.

Anyway, good luck with your rig! For an out of the box remington, it is shooting really well!

I have the bighorn tl3 short action. Super nice. I guess you can kill more birds with one stone by going short action but something about the win mag and rem mag that I like better than the short magnums. Guess you’ll save some money going short action. Then you can build it into a creeemoor or 308 if you decide to go target shooting instead

One more note about the 190gr in the 300wm. The 190 and lower .30cal bullets are pretty much neck and neck with the 6.5cm at 1,000 yards. So, unless you need the energy downrange, it is better to ring steel with the 6.5cm. The max loaded 220gr performs the best, but I am sure that the muzzle rise is huge!

I ran some numbers through the g7 for 1,000 yard, 10mph x-wind. I am a nerd...

6mm Creedmoor: hornady 108 ELD, 3,071fps, drop 22.5 moa, wind 6.0moa; energy 664ft-lbs
6.5cm, factory Hornady 140gr, 2700fps, drop 30.1moa, wind 6.4moa; energy 708ft-lbs
.308 win, hornady 168gr, 2685fps, drop 32.8moa, wind 7.5moa; energy 717ft-lbs
300wm, 185gr berger, 3,000fps, drop 28.5, wind 6.5 moa; energy 1,136ft-lbs
300wm, 220gr ELD-X, 2810fps, drop 26.2 moa, wind 5.3 moa; energy 1,380ft-lbs

You don't need all that energy to ring steel... lol. My apologies for nerding out!!

Thank you all for the input and data.

The rifle was taken out to do some 600 yd testing on the weekend.

Ammunition was 210 gr Nosler RDF bullets over 70.0 gr IMR 7828SSC powder and lit by a CCI Magnum primer. Keeping it well rolled were PPU cases which had been collet sized and neck turned after one firing. Bullets were seated .010" off the lands and were single loaded.
I only fired five of each powder load and the 70.0gr one resulted in the best group size. The groups were fired on Silver Mountanin SOLO target marking gear.
The best group was just a hair over .5MOA, or a 3.25"ish 5 shot group. (see the photo below, shots 5-9.The grid squares are 1moa)

I am liking this rifle more and more every time I fire it!
