Dumb guy has struck (again). I have a Steyr Pro Hunter and a Savage LRPV both in .223Rem. I've mixed the Lapua cases whilst tumbling them after depriming etc. I chambered all the cases in both rifles and some requiring just a tad more effort to close the bolt but nothing I'd call exceeding.

I feel, relunctantly, that I should full length resize all the cases and trim to length to be safe and sure.

OR

I know there was 40 cases for one rifle and 20 for the other; do you guys think I could just load them up and shoot them?

you can just shoot the cases will be fire formed to the chamber then keep them seperate. if they all chamber there will be no problems.
Accuracy just depends . i dont think yo will see much of a diffrence.
double check the case length make sure none arre too long

I totally agree with the above. No safety issue here at all. The only thing I can add is that I usually find that when a bolt closes with just a bit of tension the bullet can go to a slightly different point of impact than a case that chambers freely.
Possibly you could sort after loading for ez chambering.

I was faced with the same issue with 3 .223s. Size so they fit all rifles. Load to use in all or individualize for whatever reason. For example 2 of mine have deeper throats and faster twists than the third. For these two, occasionally, I'll use heavy for caliber bullets seated out farther than the third rifle will allow.

Again, the cases themselves are formed so they fit in all rifles. roger

Theoretically, a neck sized case fireformed for a specific chamber will result in better accuracy in that particular rifle. Depending upon a host of other variables in your factory rifles and handloads this may or may not be true. It most likely is. No real safety issues.

Thanks guys, I thought I'd get some positive advice.

Best regards to all of you and I'll take this opportunity to wish everyone all the best for Christmas and a safe and happy new year.

Hey Steyrl, That is exactly the way I want mine to fit, P-FLR.

When the Case is held in compression between the Bolt Face and Tapered Shoulder of the Chamber, that forces the CenterLine of the Case to be in closer alignment to the CenterLine of the Chamber than any other method of reloading. Since the CenterLines are now together, I don't concern myself with Run-Out or anything else because the Bullet is now Aligned to enter the Lands perfectly.

It is easy enough to check for yourself. P-FLR 16-18 Cases and do the same amount with Neck Sizing and Full Lenght Resizing. Load then all the same with a known accurate Load and then have a buddy hand them to you so you do not know which ones you are shooting - a Blind Test. Use the Method which is the most accurate for you, which will be P-FLR.

If Hunting in Dangerous Game country, it is always best to go on a FLR. Case life will be shortened, but that is better than having a Jam at the wrong time.

Best of luck to you.

I don't disagree with anything in your post Hot Core. But it is also true as Kraky said that cartridges which require more force to chamber them than do others in the same rifle, will often (usually?) have a slightly different point of impact.

I know from years of competing with them that anytime the bolt closes with distinctly more difficulty in my .30-BR bench guns (one Stolle, one Wichita, one AMT) the bullet is going to strike 1 to 3 bullet diameters high at 100 yards. Not theory; fact.

I don't know why that happens, but have learned that in a match I'd better dump that round in the berm down-range and chamber another one for my next shot that will count.

Hey AC, I just use regular old RCBS or Redding Dies and set them up to P-FLR from the beginning. A couple of Neck Sizing Dies are around for me to rerun the Blind Comparison Tests with.

But, I've not noticed any difference in the amount of force required to chamber Cartridges that " I " have P-FLRed. Perhaps it is there and I do not recognize it.

What do you think is causing some of your Cartridges to require more Chambering Force than the others?

I can see how that would happen if a person is Neck Sizing.
