It just occurred to me that the bullets I made for load dev on my new revolver yesterday cost me nothing except powdercoat as they were made from 100% range scrap I had collected on my last few club shoots and the melting pot and powder coating oven were both running off solar. That means they cost an almost incalculably small amount in powder.

I got a new to me pair of moulds on saturday and inclusive of mould degreasing, handle assembly and smoking I had a batch of roughly 100 of each powder coated and ready for sizing at 5pm and everything packed away from a cold start at 1:30. I find bullet making quite relaxing and now that I can do some of it for damn near free I'm extra chuffed.

Most reliable method is to take the rifle to a gunsmith to measure the headspace.

Second place is to shoot the rifle as is and set the sizing die to bump the shoulder 0.003". Yes, target and PRS shooters bump to 0.001", but we want reliable hunting ammunition that can chamber under adverse conditions.

Lastly, measuring case growth is a good indication of headspace. Measure the case length before priming, and again after it has been fired. The difference in length is very close to how much you bumped the shoulder

Thanks.

Will start working on that promised article.

Looking for a Lee .358 sizing die.

As usual I'd like to try second hand first before going to the dark side.

As per the title, looking for a Lee Pro1000 #1 shell plate (38/357) & 3 hole turret plate.

Think about what it took to make them ? How much / many scarce resources were used up
Always the German problem .. bigger is better
Russians understood the theory that quantity brings it's own quality
See siege of Sevastopol ( where this weapon was used )


Many people know about STALINGRAD not many know about SEVASTOPOL - which was perhaps worse and more important
Very much currently in the news

Do you have standard to spec ( SAAMI or CIP ) GO and NOGO gauges for your rifle ?
Really only the proper way to check the headspace - ON THE RIFLE - using factory ammo
( Of course YOUR headspace is a different matter ..    )
SIZING dies also have a role to play - IF you reload
Once you have measured and know what your rifle / chamber dimensions are -you can then work out a solution

Any idea then what could be the cause of DsJ's headspace problem ?

Length of bullet
Nosler PART 160gr = 33.02mm
Rhino 160gr = 33.60mm

Might not have a serious affect on stability.

No
