I'm finally going to fire my custom varmint rifle. It's a trued Remington with a 27" Lilja 1in14 barrel.

First batch will test 52gr Bergers, FED GM210M primers and Varget.

I'm starting at 29.0 grains. I loaded 10 each in .5gr increments up to 33gr.

Sound OK?

Your on your way! Good luck. If the Berger bullets do not pan out the Hornady 52gr A-Max work well. More powder choices to look at are H380 and H414. I have been having good luck with Winchester primers.

It's fun to carefully fire those first groups from a new rifle; write the powder charge down; then analyze those groups when you get home. If you've fired them carefully, mindful of any wind, then almost every time you'll see the groups start out at one size, shrink down considerably, then open back up. Then you load up a bunch with the optimal powder charge(s) but this time you vary the bullet jump by 5 thou at a time and again watch for changes in the groups.

If there's one thing I wish I'd done years ago, LDO, it's the switch I recently made from 3-shot groups to 5-shot groups. Not that 3-shot groups are worthless, but when you find a bullet and load with which you can repeatedly shoot a good 5-shot group, then you've got something of which to be proud.

One other tip: When working up a new load, use your watch or some other timer to force yourself to wait a certain number of minutes between shots in order to keep the barrel from heating too much. I try to wait at least two minutes or longer between shots. After I've developed a pet load, I'll rapid fire a few strings to see if/where the POI shifts, but when developing the load I don't want my barrel too hot. Just my 2 cents worth.

You're using a top-shelf barrel and components, so I'm betting you'll get good to great results right from the start. Let us know how it went, OK?
