I am fairly new to reloading and even newer to .223 reloading. Thus far have had good results, the only bullets I have used so far were some Hornady fmj from Natchez. Those bullets measured in length from .734 to .739, at least in spot checks taken from them.

Fast forward to one of the last gun shows I went to with pistol powder, the seller requireing you to buy 1000 bullets if you wanted more than one pound. Well, I did and bought 1000 of his .223 FMJ type bullets (maybe copper coated?).

They looked just like the Hornady, with a cannelure just like the Hornadys. What was NOT just like the Hornadys was the length of these bullets. the shortest so far is .734. From there it varies widely, measuring High .740s, high .750s and even one at .761.

I dont find the variance of the Hornadys to be that big a deal, a little variation in the third digit after the decimal point. These other however, show large differences in even the second digit after the decimal point.

Question 1: Isnt this a large enough difference it should be taken into account on the final OAL of the bullet? If the hornadys, averaging 2.20 OAl, and suddenly you switch in a bullet that is .760, shouldnt the OAL be adjusted to the longer bullets size? I.E., The oal around 2.20 for hornady, up to 2.246 or so to have the same seating depth?

Question 2: I indeed see load data that has .223 rounds as long as 2.260. Will this function through the average AR platform .223? I guess a better question is "What is the maximum OAL that will typically function through an AR platform gun?" Thanks for any help, I have every thing keyed up from loading the Hornady bullets and am staring at the press wondering. In the mean time I have fished out a few that fall in the average length of the Hornadys...

Thanks in advance,

Russellc
