      I was considering this mold for my 7X57 rifles.
      Has anyone had any experience with it?

      Looks like the driving bands and gas check may not fit within the neck of the case.

      That should be a good bullet, especially for new commercial barrels of .284 groove. All newer bore rider RCBS rifle bullet moulds I’ve used the last few years have produced bullets with #2 and Linotype alloys of not more than .001 over nominal diameter. Thus that mould may not produce bullets of .287 + for use in milsurps. I have the older original RCBS 28-168-FP that I got from Scharfschuetze some years back. With #2 alloy the bullets drop right at .287 – .288 which just fits the throat of my M95 Mauser. The log bearing surface of the simi Lovern design also give very good accuracy.

      If you want a mould for milsurp 7x57s then I suggest checking out these NOE 7mm’s. They are cut for COWWs so should give .002+/- larger bullets with COWW + 2% tin, #2 or linotype alloys.

      NOE also has a couple that drop .289 and .291 if you need them that large.

      I have an older Heym rifle . Not sure about the throat ,as I have never done a chamber casting.
      I also have a Mannlicher rifle and my son has a Steyr in 7mm/08

      It may well be a roll of the dice as to whether this bullet will fit any of these rifles.

      Just slugged the Heym and I came up with .285 dia so this mold won’t work.
      It probably throws a .285 dia bullet.

      European standard for 7mm is a groove diameter of. 286 – .287. British and American Standard is .283 – .284.

      I believe the Heyms are made in Germany, or Austria.
      It is dead on .285
      The rifle has never shot well with boattails.
      Only shoots good with flat base bullets.

      It really likes the Speer 130 gr flat base.
