Not yet but will do and show results.
That's my standard practice.... I began loading .303 British ammo over 25 years ago. Picked up a Redding 3 die deluxe set that included a neck size only die. Figured on neck size only until the cases get tight, and then it's time to full length resize. So far I have never full length resized one of them. For about 4 or 5 neck sizings everything is fine and the ammo doesn't even feel snug upon closing the bolt. Except by that time the case is getting ready for a head separation when the extractor tries to pull it from the chamber, ( had that happen once). My experience includes 2 Lee-Enfields; a No. 1 Mark III and a No. 4 Mark 1, Both were about the same on case life so cases get tossed into the scrap brass container after 4 loadings. If not for the case stretching, I always wondered how many reloads I could get out of a case before it needed a full length resize. I reload 6.5x55 for a Swedish Mauser sporter and get up to 7 or 8 loadings per case. Neck size only and at about the 4th loading I notice more effort closing the bolt. Then it's full length time. It all depends on chamber dimensions and Lee-Enfields are noted for generous chamber size, like StraHat mentioned.
At that point I will partially resize the case and keep screwing in the FL die until the case chambers. Sometimes 3/4 sizing works. Sometimes it has to be FL sizing. It depends on the chamber.
