My 300rum. Remington action, Lilja barrel, tuned factory trigger, Bushnell 4200 2.5-10, and a heck of an ugly paint job. I am waiting for a laminate stock (hopefully in 2 weeks) in royal camo. Right now it holds .3MOA out to 500 yards. I am just starting to stretch things out, getting 4.5-5 inch groups at 700 yards. Think I need a better scope/rings/bases to add some reach.
I think the action squaring/trigger job and barrel was money well spent. I bedded the action into a cheap factory remington stock for now, couldn't wait for the laminate to show up. I'm glad it shoots as well as it does, proves to me that thier is a huge difference between what the factories put out and what you can have built.
For me 700 yards is a long poke for 10x, I would like to get a nightforce 5.5-22 and thier rings/rail. Just need to do some more saving.
The barrel is a 1-10twist 6 groove, finished out at 27". I had a local smith chamber (minimum spec), and square the action. I did the trigger work myself (trying to learn a little smithing) and the action bedding in the stock.
So far I have had the best success with 95gr retumbo behind a 200gr accubond, with a cci 250 primer in remington brass seated .010 off of the lands. I have tried the sierra 210gr matchking, and the groups under 300 yards are similar, but past 300 yards the accubond has an edge. I might try a little more tinkering with loads for the matchkings, and I also want to try some Berger VLD's. I would like to try the nosler brass as well, but components are difficult to get lately.
