Ok, I will open this up to the brain trust here.
I have an old Remington 700 ADL SPS that was originally a .270 which I wanted to turn into an accurized long range tacticool rifle.
Sooooo...
It now has a Kwik Klip mag conversion with new bottom metal. It sits in an aluminum v-block bedded stock (Magpul). Barrel is free floated. Barrel has been swapped for a 1:10 26" 30.06 fluted heavy barrel Action has been blueprinted. Bottom metal has been shimmed. Locking lugs show equal wear. Lockup is tight. Trigger is the old stock Remy but breaks at 1.9lbs. Glass is a Sightron SIII 10-50X60. 20 MOA rail is EGW. Barrel was properly seasoned per MFR instructions.
Load generation has been done. It seems to like 168gr Sierra TMK with 53.9gr of IMR4350, Which it puts 3-4 into a 1/4” hole at 100yds.
Here is the problem, at 200yds from a lead sled rest, it struggles to hold 3" groups, with the handloads it supposedly likes.
Thus far I have recrowned the barrel, but have not tested it yet (in the off chance that there is a sine wave or rifling frequency issue, or that I over cleaned during load generation)
This damn gun is driving me up the wall.
Especially because I have a 16.25" barreled (albeit new) 700 in . 308 that holds under 1" @ 200 with a cheap-ish 10x fixed optic and factory ammo. (Aussie Outback . 308) in the same stock off a bipod rest.
Other than getting a powder that is more temperature stable like hogdon extreme H4350, what do y'all suggest?
And no, getting a new receiver is not an option. This one has sentimental value. New tuned bolt? Glass bed the action? Is this barrel just a lemon? Rebarrel (again) to a bull barrel?
Thoughts?
