I anneal my cases necks after every 2nd shooting. I have never seen a 7mm R/B that does not have an eroded neck which causes it to expand greatly. I have fired many hundreds of rounds thru my 7mm Rolling Blocks and the ONLY case loss I've had is split necks. I size my fired cases to where the necks are sized half way down to the shoulder.

After the cases are fire formed, DO NOT full length size the cases or you will be back to square one. The original 7mm Mauser cartridge had a 175 gr bullet at, depending on the source, 2000-2200 fps. Do this to all the cases you plan on using, doing it one step at a time. With the base of the case held firmly against the breech block it will form the neck and shoulder to the chamber when fired. What this does is create a false shoulder for proper head space. Tighten the die locking ring at this point. If there is a little friction between the hammer and the breech block all the better. I will finally get the neck sized down enough to where the case chambers, the breech block closes and the hammer will go all the way down on the breech block. I then start sizing the case down with a 7mm Mauser die a little at a time constantly checking to see if it will chamber. Pedersoli also manufactures classic 12 gauge side by side shotgun models. 30-30 Win and other like caliber rifles / pistols are expertly crafted to reflect traditional gunsmithing and function. 30 caliber expander button thru the case mouth and neck. Midwest Gun Works carries a variety of firearms from Davide Pedersoli, and Italian gun manufacture of classic replica pistols, rifles and shotguns. I have many 7mm Rolling Block rifles and carbines (all with different markings or variations) and I shoot them all. Of course, there is a possibility that you will be involved in a deadly traffic accident the next time you drive an auto. There is a possibility of a case head separation if new mfg ammo is fired in a Rolling Block chamber. The military barrel was replaced along with the sights and the stock was shortened.( notice the barrel has the Swedish crown stamp)The sights are part of the original conversion. After the 8X58r became obsolete, most of the rifles were converted for civilian use. What this does is create a head space problem with new brass in the old chamber. I have a Swedish Remington rolling block in 8X58R. When the 7mm Mauser cartridge and the chambers for them were standardized they came up with a measurement for the "new" case ever so slightly shorter from the bottom of the base to the start of the shoulder than the cartridge that had been around since 1892. Shooting the 7mm Rolling Blocks is, in my opinion, a hand loading proposition. Remington Rolling Block- Restoration Possible Greetings from Michigan I am not sure if this particular rifle was a 'milsurp' itself, but I do know that various models and rifles of this type were used in Americas frontier during the 1800s, and were ordered up to WWI for military use (mostly rear echelon) as I recall.
