Have reloading question about Encore Prohunter rifle barrell in 270 caliber

[GUNBIDDER 208]

 

My question is Does anybody here reload for a 270 winchester prohunter 28inch barrel and how much freebore does this barrel have?? Can you load the bullet to the rifling??? Can you share some load information along with GROUP SIZE AND VELOCITIES values?

THANKS IN ADVANCE

Hi Gunbidder take a case you have fired in that rifle now take the expander ball out of the sizer die and just tap the end of the case so that it will hold a new bullet {the ones you want to reload with} snug but not to snug so that it will slide into the case and not fall out. Now push the case with bullet in place and close the action this will seat the bullet at the lands. DO NOT Seat bullets there{pressure will go through the roof bad juju} when reloading go .100 or more deeper and check group size, or seat to factory depth OAL. Check a reloading book for powder and loads for your bullet{140gr is a good choice} all rifles are diffrent. Now take this information for what you payed for it!

Gunbidder,

Nim's right. Every gun's freebore is different and you just have to measure it. The freebore will also be different with each manufacturer's bullet (Hornady, Nosler, Berger, ect).....and you will also want to check it if your shooting the same manufacturer's bullets in different grain weights. Nim's measurement method is fine. I usually do this three or four times for a bullet to make sure "I got it right". There are also freebore measuring tools that you can buy to do this work.

If you read the nosler reloading book, they will tell you to seat their bullets from 20 thousands to 50 thousands from the rifle lands for best accuracy. Hornady doesn't mention this....they just give SAMI OAL numbers. I don't know what Barnes or Sierria books tell you.

If your seating the bullet close to the lands (like in the 20 thousands range) lower the powder charge down from the maximum and check your brass for excessive pressure indications. (Split case at the neck, or the base, or a shiny ring at the base, or a loose primer pocket). If your showing signs of high pressure, then you may want to back off the powder charge, or seat the bullet a bit deeper, or both.

I hope this helps.
