Welcome! As listed in the Handi Basics 101 sticky, shooting it without the forend will tell you if the forend needs work. Shooting one factory load and one handload isn't real conducive to finding the most accurate load, try other factory ammo or work up a load using start data and increasing the load in ½ or 1 gr increments shooting 3 shot groups each until you find the sweet spot, I've gone from 2" groups to sub moa groups with just a ½gr change MANY times! I've only shot one factory load in my 22-250 Fluted Ultra, it didn't like it at all, so I worked up a load using H380, then H4895 and the 50gr Vmax, the H4895 load rewarded me with groups well under 1" 100yd groups. It didn't like any load shot with a bipod until I floated the forend from the stud forward, then it shot well on the bipod. Just do what you need to after you shoot it without the forend, if it shoots better, work on the forend, it may just need to be floated a little or fully bedded, or a pressure point added, lots of simple choices, just do one at a time. The O-ring didn't work on mine, btw.
