Re: 338 Edge brass from RWS 404 Jeffery parent case

i asked Paul to post this picture for me because several people asked me about my progress to make edge brass from 404 Jeffery's. i finally got around to it and the results are very encuraging. the picture shows an unaltered 404 on the left, a sized to 338 in the middle and fire formed on the right. the advise i received from Bruce Baer was to only size no more than about .030 at a time and i wouldn't have any problems. the OD of the 404 is about .445, so i went to .410, then .380 and then ran it in my FL 338/300 die which has a .362 neck. that's what it looked like in the middle picture. next i anealed the shoulder/neck area, loaded it and went bang. my initial concern was the OAL of the case itself. the RWS was only 2.833 and the trim length of the edge is 2.850. after sizing, it was 2.852 and it stayed this length after fire forming. this is great! neck thickness is a bit less than Remington. after sizing it's about .014 thick. the rim is a little bigger than a standard magnum, about .538 as compared to .532. i have no problem with it going on my 700 bolt. the base of the Jeffery's is a bit less, about .538 and the fireformed from my chamber is .548. so there's a little bulge on one side which i put in the BFD catagory.

All in all, i'm very pleased with the results. i now have RWS quality brass in my edge, or soon to be both of my Edge's!

Many thanks goes to Paul for not only posting this, but giving me advise as he has basically done this before.

weight of the RWS brass is about 287 and the Rem is 270.

i put powder in one of each, both were fireformed, unsized.

RWS held 114 gr of RL22 and the Rem held 112. again this was just i pc of each with me just holding my finger over the end to get an answer for the next question.

Wow,

This definately is an interesting post for me. It sure is nice to see you guys looking for answers to brass quality issues.

I had to do a similar thing for my .243 AI. (I was splitting Shoulder in virgin R-P and Win brass.) I couldn't afford Lapua or Norma Brass, so I decided to make my brass out of .308 Lake City Match brass. Necking down in steps, turning necks and fireforming and weight sorting. Turned out to work beautifully. They handle higher pressures too.

Dave,

Are you seeing a velocity increase? Is there any accuracy difference? If there is, is it worth firefroming for?
