Remington 700 Long Range 300 Win. Mag

[Stein]

Best thing I did for my 700 was throw the stock trigger away and slap in a Timney.

  other thing I did was throw that stock out the window and replaced it with an XLR chassis.  I like your brake, who did it?

[lablover]

The brake is manufactured by Accuracy Systems based out of Colorado. They don't do bulk batches, they machine it upon order. They are good to work with. I called and placed the order and got it 8 working days later. I was pleased with the time beings it had to be manufactured. It was $110 and I had Dan Hill out of Yakima thread and time it.

I took the 700 LR to Benchmark barrels yesterday to have a muzzle brake put on the gun.  I am going to have their Miller Brake put on.  But While I was there, I mentioned that there might be a problem with my bolt, my firing pin would only lock back if I pulled the bolt back.  It would not lock back if just lifted up the bolt. He checked it and I think he said that he would need to grind the sear engagement on the bottom of the bolt. (im sorry if I have terminology wrong).  He then checked my bolt by lifting the bolt handle, pulling the bolt halfway back and slamming it forward.  Out of the 5 or 6 times he did this, the gun slam fired 4 or 5 times.  I have seen a remington 700 slam fire doing a press check.  I thought he hit the trigger or something.  He swore he didn't, I chalked it up to either bad remington trigger or he hit the trigger.  But his rifle had the same problem as mine does, and I would bet my life it slam fired that day. 

I thought that was kind of scary that it slam fired so easily.  Being that this is a review of this rifle, I thought it needed to be brought up.  I will do another range report with this rifle after i get the rifle back with the muzzle brake.

Post recall guns will not cock by simply lifting the bolt anymore. You now must lift then back appx 3/16" for cocking it.  Time for a new sear..

[kbrowne14]

hmm, good to know.  Mine only had to come back maybe 1/32.  The guy at benchmark told me that it shouldn't do that, but if it does its no big deal, as long as its not causing a slam fire.  Mine slam fired, so he will fix it.  I'm not sure exactly what he is going to grind on, but he said he would fix it.

Well, I've put about 60 rounds through the rifle and am pleased so far. The muzzle brake was worth every penny. I would estimate the recoil to that of a .243 or maybe even less. I've done two OCW load tests so far. (See Dan Newberry's Optimal Charge Weight for more on that system.) the following is what I loaded and the results.

IMR 7828
New Remington brass
CCI BR-2 primers
Hornady AMAX 208 bullets
best group was .8"

RL22
New Remington brass
CCI BR-2 primers
Hornady Amax 208 bullets
Two charges had .5" groups

From past history I know that 7828 is better performing that what it did the first time so I have loaded it again this time with magnum primers for better spark on a slower burning powder. I'm hoping I will have .5" or better with that combo. I'll post my findings when I shoot next.

Tagging

The .300 Win Mag has by far been my prfered chambering for many years. RL-22 and the 165gr Accubond make for a wicked fast combo on big game. For 90% of my shooting while hunting I'll take a little speed and a quality bonded core bullet over mass, in most cases when it comes to .30 Cals. Never had a animal stay on its feet after the first hit with the the RL-22/ 165 Combo out to the mid 600 yard range.

For the looooong stuff the 230gr OTM will hang for a loooong ways.

Do you find that the 230 grain shoot great out of the same one you use for hunting? Was there a need to optimize twist for the heavier or lighter bullet?

[Biggerhammer]

Both shoot well out of a 10 twist. Here in a bit I'm going to try both through a polygonal test barrel in a 9.75 twist Chambered in .300 Win Mag. The test barrel will be for a Standard shank Savage. The great thing about the .300 Win Mag's is, it is a very forgiving chambering when it comes to seating depth. The .300 Win Mag likes to be run hard/fast and it shoots just as well kissing the lands as it does jumping 50 thou in most cases.

this has been my experience as well. To use my mag I needed .180" of jump with the vld's.  Still shoots great even with the huge jump ( weatherby action and barrel)

Shot another round of OCW with much better results today. I used IMR 7828 with Federal 215 primers. Using the AMAX 208s helps as well since they have a BC of .648. The lands is 3.640 and I'm running the OAL at 3.633". During this test I was shooting four round groups and discarding the "flyer" with the exception of the three shot group with three different charges starting at the low end of the scale used  as foulers.

The worst group were the three foulers at 1.06". The five 4 shot groups had the following outcomes; .35", .58", .60", .75", and .95". This is a great example of how primers can make a gun shoot or not shoot depending on the powder selection. In other threads I have seen debates on primer choice, mag or non mag even when shooting a "magnum" cartridge. My tikka 300 wm with 71gr of RL22 with a CCI BR-2 (large rifle) primer shoots @ .48". Same load with a magnum primer is over 1.25". Faster burning powders can use a large rifle and work well. Slower burning powders need the magnum primers.

Ultimately, I'm extremely pleased with how the rifle shoots. With the large brake it shoots like a .243 even when pushing a 208 grain bullet over 2900 fps. The only dislike is the trigger. It is absolute garbage. I really want to keep this a low budget gun, but getting rid of the trigger is next on my to do list. It is absolutely horrible, even at 3lbs. That being said, for $699, I'm looking at a 1/2 MOA rifle instead of spending thousands on a custom. I'll take it.

Not to shabby!

  looking at your targets i would take the 0.6 load and see how it does at range. I always count all shots in a group unless i know it was me that caused the flyer for sure.
