New rifle need good load for 243

[Tx300mag]

the rifle is a Remington 700 varmit 1:9.125 or 250 whatever big green decided to abstractly use.....

Anyway I did some google searching before I shot the rifle and went for the H1000 and 105 AMAX it shot 1"@100-
Not what I was expecting.....

I want a bug hole group.....

Here is some specific on the rifle:
Remington ADL varmit from Dicks (NEW)
removed the stock, trigger and cheap base and scope and installed the following
Mcmillian M40 htg stock (bedded in devcon)
jewell trigger
weaver 1 piece tac base
burris xtr rings
vortex viper 6.5-20x44 (known good from previous rifle)
everything properly torqued and all.......

It shot factory federal into a 1.25-1.4" group--- not my best gun I have opened from NIB.
I am hoping this thing is just not broke in and I can dial it down to the .2-.3 range hell I would be happy at .4-.5.

one more bit: the barrel was cleaned with sweets, butches bore shine and I used Isso for about 40 passes before I even squeezed 1 off.
So its my first post and glad to have been around here lurking seems like a lot of good info here!!!
Thanks in advance.

Give it a little trigger time and maybe that will help, but you shouldn't really expect a one holer from Remington with out saying a lot of prayers.... especially with factory ammo, just to many variables in the complete package...

The twist of your factory Remy barrel may not stabilize the 105 A-Max fully to shoot some small groups. Try some 87 grain V-Max or maybe some Sierra 95 MK's lit off by 4350 class powders. Sounds like you are on the right track so far with everything you have done so far.

Without a doubt, the first powder I'd try is IMR 4350, especially with bullet weights 80 grain and heavier.

The 90 grain Nosler shoots sub 1/2 moa in my Rem 700, same twist as yours, with IMR 4350 and Federal 210 match primers.

Another excellent bullet is the 85 grain Sierra BTHP, again with IMR 4350.

Berger 90 with H4350 is best in my 10 twist. Nothing else was as close.

Don't expect a factory barrel to shoot like a Krieger, Bartlein, etc. If they did, none of use would be using hand-lapped custom barrels.

Shoot it and enjoy & when the barrel is ready for replacement, you have the basis for a custom barrel & it will be like getting a whole new rifle.

Guess I just got lucky and got a good barrel.

Stock 700 VLS in 243 with Jewel trigger and Nikon scope.
44.5 gr. H414, 85 gr. Sierra hpbt, Lapua brass beveled and uniformed
flash hole, Federal 210m primers,full length sized (Redding) and I let
it jump.
Nothing fancy and I'm getting .25 MOA groups at 100 yds. if I'm shooting well.
I've just started shooting at 300 yds. but just ordered a new scope to get
more magnification so I can see the target. My budget led me to choose a
Weaver T36. I'm afraid I'm about maxed out at 85 gr. though with the 9+ twist.
I'll find out. When this throat wears out a nice custom barrel with a faster turn
will be next. I've seen no evidence of copper fouling so I only light clean with
shooters choice, once a bit of CLP.

Having a Jewell trigger helps over a factory for sure.

I've had good results with 46 grs H4831SC, CCI 200, 95 gr Nosler BT.

LOL...THIS IS WHERE IT ALL STARTS!!! I remember back in the day when i wanted that!!!lol what fun it has been

How did you do load tests, did you test different bullet types and masses? The lenght of your bullets should probably not be more than 1.1" or 1.2" for the twist rate of the barrel.

 

[GSPV]

Start with 40.5 grains of 4350 and adjust up and down behind any of these

Sierra 85 gr HPBT
Berger 90 BT
Berger 87 VLD Hunting
Hornady 87 VMax
Nosler 95 Partition

Back in my teens, I killed a truckload of groundhogs with that 85 HPBT. The same load with the 95 gr Partition is poison on whitetail, but getting warm.

One word of advice: Take good care of your brass. It is the foundation of everything.

 

[joecob]

Heartily agree about brass.
When I first began to de-burr and uniform flashholes I saw a very
dramatic improvement in accuracy. That was with Norma brass, though
I've since switched to Lapua. Still believe in brass prep to the flashhole
at least.

I also agree that you probably started out with too heavy a bullet for
the barrel.

 

[Tx300mag]

Has anyone had luck with the 95 Berger vld in the sps varmit or vls?

I loaded a few with h1000, and 4350 so we shall see!

I guess the 95 cbt bullet will be my next attempt and the 85 serria

You'll have lots of fun exploring the possibilities with your rig. Started on the same journey some 40 years ago with a heavy Ruger .243. Still have that old beast, had to put a nice Hart barrel on it after about 2000 rounds and its still going strong against p-dogs. Can't go wrong with H414 or H4350. Trigger clean-up and good optics will go along way with verifying what loads to use. Might have a hammer of a load but if your trigger breaks inconstantly or your optics are out of whack you'll never realize it..Have to reduce the variables, especially when load developing. Good Luck, Eric in DL

Buying a Factory Rem 700 is the luck of the draw as far as action trueness and chamber to bore trueness goes. For the receivers that I have blueprinted, the best receiver needed .010" of clean up cut on the threads after the bolt bore was dialed in as close to .0001" as I could get it, the worst needing about .032" of cleanup to get it true. That's a pretty big differance! I just recently conducted a factory barrel test to see how good I could make a not so good shooting 700 shoot. The gun was a $399.00 Wal-mart Rem 700 SPS chambered in 308 with a varmint barrel. A stock 5 shot group was about 1.5" at 100 yards, this thing just would not shoot any better than 1.5". So I broke it down and did the following: reamed the bolt bore raceway to .705", trued to threads, face and lugs in the receiver, trued the bolt face and lugs and sleeved the bolt and turned the sleeves to about .704" for a .001" clearance between the bolt and bolt bore raceway. Cut off the thread tenon on the barrel and dialed the bore in to .0001", turned a new thread tenon, re-chambered the barrel with a .308 "match" reamer from PTG. I didn't add any aftermarket parts (jewell trigger, stock etc... but I did tune the trigger to about 3 lbs) Shot a few groups at 100 yards and it would put five in about 1/2" to 3/4" hole. Then took it to my buddies 700 yard range and shot about a 6" to 8" group. I only wish I would have tested it at 700 yards before all of the work. This gun will get a new barrel soon, but would be perfectly acceptable the way it is for a long range hunting rig. (500 to 600 yards) So when you have a bone stock Rem 700 it really is the luck of the draw.
