Here's a pic of a round .015 and one that fits the mag.
When your trying to get the very best groupings from your rifle,you'll find out that almost any bullet will shoot best when it's getting close to the lands. The problem with most production rifles are that they have long throats,and your COAL will almost always be longer than magazine length.
So you have to decide whether you want the very best shooting loads for your rifle,or the very best loads that fit in your magazine!!!
I disagree with Willfully Armed to a point.
When I start loading test loads for any given bullet,I always load in .5 gr or 1.0 gr increments. There is a sweet spot in every barrel,and there's no need in wasting a bunch of time/money loading each test load set .1-,2 gr's apart.
Since your 48.0 gr and 49.0 gr loads shot best,I'd start over with loads at 48.0 and work them up to 49.0 at .2 gr increments now. Then where ever they shoot best,load some at .1 gr increments on either side,and see if they tighten the groups up even more.
