Well, got around to dooing some serious shooting Sunday and found out an odd result.
Ballistics be danged, not sure how or why, but the rifle was zeroed at 25 yards with 115gr WWB. moved out to 50 yards and was about an inch high! (No drop. How???) so we moved the target back to 100 yards, thinking & expecting the bullets to fall like a rock. Nope. Only about 2" under point of aim to center of 3 shot group. The group was about 4" wide by 2" in height. Think the 10 to 15 mph crosswind had something to do with that. Switched loads to Mil Surp 115 FMJ & group size opened up to about 8". Did not get a chance to shoot the PMC Bronze 115gr FMJ.
NOW: Here is where it gets really odd, switched loads over to Federal 147gr FMJ, fully expecting the much heavyer bullet to drop quite a bit. Kinda figured it would drop 1 to 2 feet from POA. NOPE AGAIN! lol.
Much to my amazement and confusion, in the first 5 shot group, one bullet hit the bullseye and the other 4 shots were all within 3" of that shot!
Holy Cow!!!!!!! This little pipsqueak really shoots good!
But I can not explain HOW the 147 gr managed to have the same trajectory as the 115gr. Ballistically, it's just not so.
But as I seem to recall one gun scribe once said, "Ballistics be damed, it's results we are after!" ( Forgot where I read that. In one of my many gun mags I'm sure. lol.)
As the skys were turning Iron clad & the air was getting too cold for this 'ol southern country boy to stay outside, just for the heck of it we moved the target out to 135 yards. By this time, the dot in the scope not only coverd the entire target, but also the entire target stand! lol.
By this time, using the Federal 147gr, I shot a 10 shot group and the group size had opened up to about a 8" spread. Hard to tell due to group size, but I would guestimate about 4 or 5 inches under bullseye from the center of the group.
Maybe if it was warmer I'd done better. Maybe if I had slowed down & took a little more time between shots I'd have done better. Maybe if it had a 2.5X or 4X scope instead of a 0 power Dot sight it would have done better.
Whatever.
I am still quite pleased & amazed at the accuracy of this little Hi-Point 995!!!
No tac driver, but HAS absolutly Exeeded my expectations!
And that is something that does not happen very often!

Shot mine off hand today at 25 yards for the 1st time, about 30 rounds and one golfball sized hole out of the target. Alot better than I had expected, and could see people around me take a second look when I brought the target back. Not exactly shooting slow either, with factory ghost ring sights.
The general theory I hear is that the heavier bullet causes increased recoil, so the muzzle rises more, and with the longer barrel of the carbine, it is effectively higher when the bullet exits the barrel, so within a certain distance, it will impact higher on the target. BUT.... that heavier bullet will drop more further on out. Basically, by adjusting our handloads within pressure tolerances, we can make two different weight bullets impact the same target spot at a specific range.
So far I have only used 115 grain loads in my M995. It really likes the steel-cased WOlf ammo!

WOW! Exelent observation! That would explain it! I think you hit the nail on the head. Thanks!

Your gun likely shoots much better than you think. You have seen the limitations of a red dot sight first hand. Unless you pay big bucks for a 1 MOA dot you can lose your target behind the dot. They are great for quick close distance point type shooting. However, they aren't the cat's meow for precision (and or distance) shooting. At those distances you probably would have done better with the factory sights because they would allow you to see the target at 135 yards.
Put a low power 1.5 to 4 power scope on there and see what she'll really do. Then tel us about it.

I have a 3x9X I am going to mount on it just for the sole purpose of accuracy testing. Will be using Outers Varmiteer rifle rest, so 99% of the "human error" will be removed.
What it does with that set up is as good as it can possibaly do.
I will report back with my findings.

When using pistol caliber ammo in a carbine, the ballastics will go up around 100 to 300 fps more, because the powder has more time to burn, which will give more muzzle rise because of the extra muzzle energy being put out. Also, ammo manufacturers will adjust their powder grains according to the bullet being used to help keep muzzle energy at a certain constant velocity. This is why, when you read about a given ammo ballastic, in this case a 9mm, that no matter what grain of bullet you're using, the velocities are usually only a couple hundred feet per second apart, but the points of impact can be as much as 6" difference for a certain distance. The largest difference will be from the "knockdown" power between a lighter grain bullet(115) compared to a heavier grained bullet(147). This does not include any handloaded ammo or "magnum" ammo where they're known for being just better for any given caliber. You will also find that your Hi-Point carbine, just like your centerfire hunting rifle, will favor a certain grained ammo better for it's accuracy, if accuracy is what you want. Me, I haven't found that ammo yet--I'm having too much fun throwing out all kinds of lead to worry about accuracy right now.

I believe it's because the heavier bullet is slower and the barrel raises more before the bullet clears it during recoil. The recoil should be about the same between a lighter faster bullet versus heavier slower bullet assuming the product of weight X velocity doesn't change much and it generally doesn't.
