I tested a few loads today for a .243 that belongs to a friend. I found a load that shoots less than 1/2" at 100yds using a 100gr remington corelokt and 41.0gr of IMR4350. The velocity was 2785. He uses this gun for a hunting rifle for his kids. The velocity seems a little low and the powder is almost at the max according to the books, should I try to load it up a little or leave well enough alone? The temp was 90+ and the humidity was 70%, I dont think the load will be too much under any condition if its not now.

1/2" with corelokts, I'd leave well enough alone. I did similar with my 7mm-08 hunting rig. I bought a bag of win brass and they were a little beat up from the shipping so I thought I'd fireform them. Went and got the cheapest Hornady bullets offered at the local gun shop. Had just enough of some powder I used to load 30-06 with (sold the '06). I threw it all together and it shot 1" groups at 100. A couple quick shots to get zeroed and 2 four round groups. Both measured under 1". I stopped fireforming. I have taken three bucks and a coyote so far. All the fancy bullets and stuff will have to wait till these rounds are gone.

Re: what to do?
The very first load I threw together for my .243 was with IMR4350 and Nosler, 95 grain partitions that shot 1/2" at 100 yards.
My son still uses that rifle, and load for deer, and it seems to anchor them as well as anything else I've used, and I've used 7mm-08, .308, 30-06, 7mm Remington magnum, and .338 Winchester magnum.
