Seating 45colt bullets

Loading 250g XTPs for my Redhawk 4.2 in 45c and 45ACP.
I've resized and flared 100 cases (Hornady). Bullets are .452 in diameter. Cases are flared enough to get the bullet started. When seating the bullets some cases seem to drag more in the die body then be difficult to fully seat. I have to exert more pressure on the handle than usual. I notice this happened frequently in the first thirty I loaded then stopped. The die is backed out far enough to avoid the crip. I've concerned the ones that required more effort to seat will somehow have higher pressure. I've only loaded about 200-300 45c cases up to now. I've loaded thousands of other rounds in various calibers and did not have this seating problem. I also wondered if this is somehow more common in the 45c caliber. I'm using Redding dies.

i would be pulling a few of those loaded rounds to check the powder charges. you don't mention what powder or weight but it almost sounds like you're compressing the load when you seat the bullet. don't know for sure, just grasping is all.

for .45 colt i'm using missouri bullet's .45 elmer k .452 dia, 255 gr. swc over 22.0 gr. of lilgun. i just finished loading 1,500 rounds and have not experienced what you have.

never used the xtp for .45 colt loads but do use the 180 gr. xtp for 10mm and not experiencing anything unusual there with them.

redding dies are first rate but there could be a problem there, also. hard to say without seeing them.

wish i could be more help.

Rugerfan57, If you are using Hornady brass, there's a good chance it is "LEVERevolution" brass that was loaded with FTX bullets. This brass is shorter (1.215") than standard SAAMI spec brass (1.275~1.285") so you will not be able to seat normal XTP bullets properly. Make sure you measure your brass and if it is "FTX" brass, do not use it with standard bullets using data for full length brass.

Sorry, left out some data. These are new cases that were not trimmed to the FTX length. I do have a hundred of those loaded and keep the used cases in a separate coffee can. I'm charging the new cases with 24.2 IMR4227 and it is not supposed to be a compressed load. I've experienced some drag in the past when the die is closing the case mouth but never like this. I don't think the cases are over flared either. I've loaded 250 Rainer .452 and the FTX before without having this issue. I have some 250g Nosler in .451 diameter and will load those next. I don't remember having this drag issue when I loaded the test rounds for the Nosler bullets. Perhaps I'm making much ado about nothing but I got concerned with the amount of extra force I had to use to seat the bullets. Another odd fact, not all the ones I seated had this happen. I'm loading on a single stage Rockchucker and using a Hornady electronic powder measure. Charge weights are checked with a RCBS 10-10 scale. I also measured the diameter on about a dozen of the Hornady XTPs. They were all the same diameter. I also pulled their dies apart and cleaned them yesterday. No lube on the cases.

Some updated information to share. Yes, the cases were resized. I bought new brass to load the 250g XTP and 250 Nosler Sporting. I just made a dummie round for the 250g Nosler and no issues what so ever. I've been obsessing about this for three hours. One important fact, one batch was Hornady brass and the other was Winchester. I wondered if the wall thickness of each brand were different. It appear this might be part of the issue. Add this to .001 difference in bullet diameter and perhaps I'm getting the drag due to the .002 to .003 increase in width of the case and bullet being seated. I'm thinking that the XTP should be used in the Winchester brass instead of the Hornady. The Hornady brass seems to have a thicker wall. Just a thought. I have to walk away for a while.

I had very similar situation last week loading 45 colt.

I used new Starline brass and a Redding Competition Seater. I was getting hard to push rounds and some even seemed to bulge the brass out on one side. I thought it was not getting started straight. When I was sure it was straight in all the way, it made no difference. I also verified that the seater plug fit the boolit end correctly as that can cause misaligned seating.

After walking away overnight, I decided to reboot:
I finally just backed the Redding seater die out a turn or two and reset the adjustment knob on the top down. No more hard to seat and no more bulge in the brass on one side.

Yeah, I thought about that yesterday and realized I'd already backed out the die enough so the seating stem was almost to the last thread. Therefore, I know I'm not hitting the crimp ring when I seat the bullet. Went back to the Hornady manual and saw they called for a Winchester case for that bullet and powder choice. Made a couple dummies and had no problem. One ironic note, the Hornady case was noted in the load for the non T/C and Ruger loads. That combination is not going to work in my die. I'm not sure why but believe it might be a tight tolerance in the seating die. I tried to pull the bullets I already loaded and the case tension was so strong the bullets would not come out. Into the scrap can they went. I'll fill the can with oil to kill the primers. Glad I did not decide to shoot them in the gun. Yikes. A non-fatal lesson learned. I might call Redding to see if they've had any problems with the die I have.

we all know the frustration of doing a task that is usually simple and clean and then getting erratic unwelcome results.

hang in there. keep breathing. seems like reloading always comes around in the end.

good luck, bud,
