My son is stationed in Hawaii. While he was home on leave he got the Trump $1776 bonus and picked up excellent condition (albeit older model) Christiansen Arms .300WM. I want to start picking up ammo for him by adding a box or two to each one of my ammunition orders so he has a small stockpile when he comes home in a couple of years. He bought a box of Hornady Match 178gr ELD but didn't get a scope mount in time to shoot the gun before he had to go. I have no experience with the .300 so I don't know whether to buy him 178 or 195gr. Rifle will primarily be used for shooting at 4-600 targets unless he lives somewhere that he can hunt with it.

Which do I stock up on for him?

Edit: He said he did shoot it with a loaner scope and mount but only at 100yds with SP hunting ammo, so I still don't know which grain weight ELD.

If you get him a couple of boxes each order for a couple of years, he will have a hodgepodge of mixed lots that will shoot differently from every other box.

Get him a simple single stage press, a set of dies and some components like primers/powder and bullets.

At 4-600yds it won’t matter which round from a BC perspective, just get the one that’s cheapest or most accurate. That’s 5.56 territory and any 300WM will easily do that.

OK, I'll just keep buying the 178's. Thanks for posting.

Some 300 wm’s will definitely show a preference for one over the other. Unless I could confirm the 178’s are better in the rifle I would not stack them deep. I have seen some win mags have a preference for the heavies. I would buy a couple boxes of each and then verify the rifles preference before stacking deep.

Good luck.
