    Posted: July 29 2012 at 9:11am
I just started reloading and made up a bunch of rounds using Federal brass and Sierra bullets. This brass has never been reloaded before. When chambering these rounds in my No. 4, they required a little effort to close the bolt, though they shot well. When I got home from the range, I decided to try chambering some rounds from the same box in my No. 1 Mk. 3. They chambered easily, without any additional effort to close the bolt.
I have always used Privy and Federal in both Enfields without much thought and they have chambered well, so I was surprised. The fired brass looks completely normal.

I'm too naive and inexperienced to say! Looks like the PPU and Remmington brass  is more substancial, but couldn't say for sure.

I'd check the length of the cases, I have had to trim new brass before. Also, check the overall length and make sure you're not forcing the bullet into the grooves.

Noslers... I'm reloading because I'm cheap! Bullets are expensive up here in Alaska!
I think I will have to load rounds with the bullets a little deeper for the No. 4 and just start keeping them separate from what I use in the No. 1.

Go easy on this because seating the bullet deeper will raise pressure. Try putting an empty case in the No 4 and see if the bolt closes easily. You could have insufficient headspace ( not likely). If that is OK, put a bullet in the case a little longer than called for with no powder ,primer or crimp and chamber it and close the bolt. Pull it and measure the over all length. This length is where the bullet is touching the lands and you should compare this to what you have been using for the over all dimension.

If you "paint" one of the bullets with a magic marker you'll see if the bullet is contacting the throat as it'll scrape the color off if it is. Much easier than guessing!Wink

Lee Enfields shoot best with as long an OAL as possible, limited only by the magazine.  Fire-formed cases also shoot better.  Something I have never tried but it is said that if one marks the case so that it can be chambered with the same orientation each time improves accuracy.  It is also said that the O-ring trick with full length sized cases has the same effect.  Again, I have never put this to the test.

Notching the rims helps with neck-sized cases fired in off center chambers. Other than that I've never foiund it to make a big difference.

I've never checked any of my rifle chambers for off centre chambers.  Is that a common occurrence with Lee Enfield chambers?  I do know sometimes the extractor can push the case to one side (it shouldn't if the extractor is correct for the cut-out but several of my rifles have mismatching cut-out and extractors.  One is so bad it only grips the edge of the rim.

Fairly common, I had a #4 Mk1 (T) with an off center chamber. It shot fine though but the brass was funky-looking with the off center expansion!

I don't know if they are off center or just large. I recently picked up some 45 colt brass from the range brass can. When I got home, 3 of the 45's were in fact 44mags and it was obvious they had been fired in the 45. One side of the case belled out to meet the chamber and was obviously ballooned, the other side remained flat against the chamber. I'm sure the 45 chamber wasn't off center, but the brass looks that way as it didn't expand evenly to fill the space.

That usually happens with large chambers in the Brit.  The case will almost always sit to one side in the chamber, in one case at least, due to the extractor.  The extractor should be pressed away from the case by the extractor cut-out but sometimes doesn't.
