Plain Base " 101 ".


Staff member
It is no secret on this forum that I enjoy shooting plain based , reduced velocity, rifle loads.

Some have tried it with only limited success. I don't pretend to know all the answers on the subject, but I can share what I do know.

  • The base MUST be filled out well with a smooth sprue cut !

  • The drive bands must be filled out well with you sorting through the bullets ( prior to lubing and sizing ) , making a close physical inspection. Be " ruthless " in your standards of inspection ! ! If you see a drive band that is not filled out well, drop that one into the remelt can. I don't weigh my cast bullets, but if you've got the time and want to go the " extra mile " in consistency then by all means do it.

  • Even if you've done the above perfectly, you can ruin everything with excessive speed. I've found great accuracy in the 1050 fps - 1200 fps speed zone. Trying to push a plain base bullet to 1,500 , 1,600 , 1,700 fps and beyond, treating it like a g/c bullet, is a quick prescription for a " NO Joy " trip to the range.
When you find a plain base mould and find the diameter that your particular rifle likes, with the proper amount ( don't over - lube ) of bullet lube you'll be well on your way to success.

These will make for some fun afternoons at the range this fall.

In .30 cal. rifle, you could do MUCH WORSE in your selection of a nice plain base bullet style than this one. The SAECO # 315 is an all time perennial favorite of mine. Here is the Accurate version made by Tom , 31- 175 BP , both cavities being plain base.

Developing some super accurate loads, saving powder, not paying for gas checks, and going easy on your ears, your rifle and your shoulder all make good sense to me.

10 rounds @ 50 yards shot with my 30-30 Handi rifle .

Here is the load .

Good Shooting to all of you,
