foxtrapper.... the bullet may be out of balance----lack dynamic balance. If so, more velocity is apt to increase the flywheel effect. For accuracy the pistol comes first... followed by the bullet... followed by the load. You have accuracy from the Hornady 210 XTP. Wouldn’t be surprised if the same 220 Hammer shot poorly from another .41 Mag of demonstrated accuracy.
A fine barrel cannot save an unbalanced bullet.

David Bradshaw So you’re saying the bullet design is inherently inaccurate? Or does the actual casting have affect? Bullet is 50/50 ,ww/pb. They fill out and look good, so there’s that! lol |

If they will chamber, try some at a larger diameter. I know the dimensions of your revolver are tight, but try the biggest diameter bullet you can fit in the case and cylinder. .410 seems (seems) a little small.

They fill out and look good, so there’s that! lol ***** foxtrapper.... not saying the bullet is bad, just that it’s on the short list of suspects. The short list includes: * measure groove diameter and bullet diameter. * target the bullet in another .41. Some molds are more uniform than others. COG and COFIf the Center of Gravity (CoG) and Center of Form (CoF) both occur in the longitudinal center of the bullet, chances are the faster you push it, the less stabile it becomes. A symmetrical wadcutter is a perfect example of CoG and CoF in the same place. When CoG and CoF coincide, accuracy may work below the speed of sound and at close range (25 to 50 yards), yet deteriorate as range insreases (75 to 100 yards). Late 70’s-early 80’s I shot a .44 290 grain SWC called a “Hammer.” The Center of Gravity was well behind the Center of Form and it shot well. Better to pinch a bullet than rattle itIn the old days, there was general agreement that cast bullets preferred to .001” greater than groove diameter. You could save time & ammo, and help solve the problem, to ask a couple good shots on the forum to target your Hammer. David Bradshaw |

My first thought would be that particular bullet and your gun do not like each other. So have someone else or you, shoot it from a different 41, provided that one is a known accurate gun. Technically it could be the bullet that is at fault and not the gun. If the second gun shoots the load well, then look at the difference between it and yours, twist rate would be my first thought on that. If the second gun also shoots the load poorly, then it could be the bullet itself being a poor design, poor casting, or something. You could also check the barrel of your gun and see if there are issues with it?? Poor chamber, poor rifling, bad muzzle, etc. Try a different cast bullet of the same diameter but known good accuracy and see if your gun just doesn’t care for cast of that diameter.
Do one thing at a time and eliminate each thought systematically, keep a list. It can be frustrating but systematic elimination of each Individual item should lead you to a cause/answer.

Since I know the gun shoots great with the hornady xtp ,I’ll try the suggested powder, hs-6, longshot and unique. I’ll keep them to the suggested starting loads. Trouble is the Lyman 51 and the Lyman cast bullet manual do not list those powders. Any starting suggestions folks? Time to search the inter webs! Found so far 220 jhp, hs-6 and longshot….. only one grain difference between starting and max! Yeesh!

Keep in mind, you can use plated data for lead too, gives you more load data to choose from, seems to be a lot of plated data for 220 gr 41 mag

The FA 2008 is a proven shooter & yours is doing fine with the one jacketed load you've ran through it so it's going to be fine with cast, just maybe not that cast. But don't give up on it just yet. Try 8.0 grs of Unique, also try 17.0 grs of 2400, and try 20 grs of 4227. If one of those loads doesn't shoot then switch bullets or let me know & I send you some 230 gr Keith, or 250 gr Miha HP's that are powder coated, if they don't shoot, have David shoot your gun! I don't think it's bullet diameter.

Still horrible! Have a pic of the 8.0 unique @50 yrds. No way to post. Thank goodness for the hornady 210’s!!

Have you tried both solids and hollow points? Might be pure folly, but...

You might pull a loaded bullet & measure it. It's possible your expander ball is a bit too small & when you're seating the bullets you are squeezing the bullet down a bit. That barrel will shoot cast for sure, just have to unlock the problem, it's kind of fun really. You might also try deep seating ala David Bradshaw, if you haven't already.
