Just loaded my first few rounds of .50AE for my new (To me) Desert Eagle. It cycled fine, but POI is about 6" higher @ 10ish yds than the Western Metals ammo I picked up, which impacts more or less at POA. 350grain bullet though. Both are consistent, i.e. I'm getting groups, no erratic flyers. If I'm flinching, which is very likely, it's not horrendous. Lol. I'm loading 30.5grains of H110, CCI #350 magnum primers, 300grain Berry's RSFP bullets, new Starline brass, 1.575" COAL. Can I bring the POI down by adjusting the powder charge...? Is it the lighter bullet that's causing the POI change?
 
sounds pretty normal to me any change in load bullet weight powder charge etc can change poi that's why most good firearms have adjustable sights. good luck

yes, bullet weight has an effect on POI.

Try loading the same weight as the Western metal.

or, adjust the rear sight.

I spent $175 on the 300 grain bullets, I'm not really interested in going to another bullet weight, lol. Rear sight is non-adjustable. Might have to see if I can pick up an adjustable rear though.

You betcha ;) Have a holster and 7 mags for it.
 
You might spend just as much on adjustable sights. Can you pull some Western Metal bullets and load them as an experiement?
 
lighter bullet = faster velocity = higher POI
one item to consider is the bullet itself - is it comparable to the factory bullet or is it just plinking bullets -

Might. But then at least I'll be able to dial in a load.

When I was setting up my seater/crimp die, I accidentally seated a bullet in too far. Then I realized that I have no reasonable way to pull a .50cal bullet, lol. I ended up mangling the bullet in a vise just to save the powder/primer/brass. So nope, can't really do that. Good idea though.


Bullet construction looks very similar (Plated TC/round shoulder).

Not exactly. Generally, pistols will shoot high(er) with heavier bullets.

This is what I thought,
Heavier,slower bullet means longer time in the barrel as it recoils upward resulting
in the bullet leaving later in the recoil arc.
But I have learned over the years that I am not an expert.

Hm. So judging by this, I might be able to lower POI by increasing my powder charge, and increasing velocity?
 
I could be wrong, it wouldn't be the first time, but I doubt you can fix 6" of POI at 10 yards through load development. I can't say for sure because I've never loaded 50 so hopefully someone with more applicable knowledge will help out. If not go to the Benos forum.

P.S. Are you sure there's not something else wrong?
 
I develop a load for a pistol that is accurate and suitable for the purpose. In this case you need accuracy and maybe power to knock down steel.

once I have the load, I adjust the sights. For many pistols this has meant buying a Dawson Precision front sight of the correct height and width.

Height changes POI and I find a narrower sight suits my old eyes, and I also change to a fibre optic front.
 
I realize its a dessert eagle.........
If you're going to stick with the lighter bullets, how are you with a file?
Lower that rear sight.....a few strokes at a time.
Dawson Pres. makes great sites, takes a bit of time to bring them in, though.
 
Generally a heavier bullet will impact higher than a lighter bullet from a handgun, reason being the heavier bullet is usually traveling slower so it is in the barrel longer and the recoil causes it to hit the target high.
