40 cal lead issues

[shootinxd]

Having some trouble getting a accurate load.My XD shoots great with beery's 155grn plated.My bullets are 175grn lee TC using any where from6.0 grns.Power pistol 6.5 grn working down .2 grns at a time to no avail.Any suggestions,I am at wits-end.

Need more info.

Leading where in the barrel, at what loads of PP, BHN or alloy composition, would all help.

Random questions...no particular order...

- is your barrel clean?
- have you slugged your barrel? Do the bullets fit properly?
- have you double checked the load data
- have you tried a different recipie
- are they lubed properly

Q

No barrel leading,just not accurate.Barrel slugs right at .400,bulltes sized to .4015,but dont shoot worht a darn,Like I said loads with accurate #5 starting from 5.5grn-6.2grns.Power Pistol from 5.0grns-6.5 grns.Best of the bunch was 5.7grn over water dropped,but even at that 5inch group from a rest @ 15yds is very poor.I can off hand shoot my Plated 155grn on 7.2grn of AA#5 @ 15yds 3" group.

I'd experiment with your crimp and also weigh your bullets (sized but without lube) to get a batch all within +/- 5gr. Not all the time but just to be certain you're giving yourself the best opportunity for a tight group.

Try a different bullet design - maybe your gun just doesn't like that particular bullet. Get a box of commercial cast and see if that changes anything.

I've not heard of XDs being bullet-sensitive/particular, but I guess it's possible.

Out of curiosity, what kind of accuracy are you getting vs. what you want to achieve?

Quoheleth I have shoot several groups of 10rnds,average size is more that 6-8" @ 15yds from a rest.Off hand with plated I can shoot sub 4" @ 15yds all day long.3" groups @25yds from rest would work.

Maybe your gun just doesn't like that particular lead bullet. I don't understand why, but I don't understand why my wife doesn't like Reuben sandwiches, either.

My last thought...you said the gun likes 155gr plated, but you're running 175gr LTC. I wonder if the issue is bullet weight or construction (which is what you're really asking, too, I think). Do you have access to either heavier plated bullets or lighter cast lead?

I wish I had something definite to tell you. Maybe RCModel will come along - he usually has an answer when no one else does.

I have tried several different commercially cast .40 lead bullets (round nose, truncated cone, semi-wadcutter) with fast (Bullseye, AA#2, HP38, W231) to medium (Unique, HS6, AA#5) burning powders in a Ruger P94, S&W 4006, and S&W 610. Couldn't get any of them to shoot anywhere near as accurately as a jacketed (not plated) bullet. Waste of reloading components in my opinion. Same experience with 9mm also.

I have a .40 cast bullet load that is a tack driver in my Colt 1911/.40 and my CZ-75/.40.

Missouri Bullet 170gn LSWC, 3.8 gns 231, 1.040 OAL. Colt does around 1.0" from a rest @ 25 yards; CZ does around 1.25-1.50" @ 25 yards from a rest.

Not saying anyone else's pistol will do this.

I have a friend the is going to give me some his 155 cast,hope this is the answer,I love casting my own boolits,lol.I thought I might mention that the XD is a 4" barrel.We shall see!!!

Keep us posted and let us know how the experiment goes.
