Secondly, the case volume of the 303 Epps is smaller than the 30-06. Another reason why it should do a great job.

Your other concern would be the brass - it can only take a certain amount if pressure. It does not help to get two or three shots from hard sourced brass.]]> Reloading Methodology Ds J https://systemz.online/reloading-methodology/safe-chamber-pressure-303-epps-improved/#post-5026 https://systemz.online/reloading-methodology/safe-chamber-pressure-303-epps-improved/#post-4922 Wed, 24 Jul 2024 09:05:18 +0000                                       :-]]> Reloading Methodology Treeman https://systemz.online/reloading-methodology/safe-chamber-pressure-303-epps-improved/#post-4922 https://systemz.online/reloading-methodology/safe-chamber-pressure-303-epps-improved/#post-4921 Wed, 24 Jul 2024 09:03:56 +0000
If you want less recoil then try 42gr S321 with the 180gr bullet. Pressure calcs as 45K psi and 2450fps. You now have a Lee Enfield load.

I do not like recoil, it deducts from my enjoyment, would like to keep shots enjoyable.]]> Reloading Methodology Treeman https://systemz.online/reloading-methodology/safe-chamber-pressure-303-epps-improved/#post-4912 https://systemz.online/reloading-methodology/safe-chamber-pressure-303-epps-improved/#post-4911 Tue, 23 Jul 2024 23:50:10 +0000 Or you can try to email the author at steve@303british.com

The P14 action is pretty much the same as the P17 action also called the M1917 Enfield. Which were manufactured to shoot .30-06 rounds. .30-06 have a SAAMI max pressure of 60,000 psi.

The only practical difference between the P14 and P17 is the chambering and the bolt head. The limitation is usually the brass. As the Epps case has the same taper as a .30-06 case, I am quite confident that both actions can be used to the same pressure.

When loading to .30-06 pressure, just mark the ammo to not be used in a Lee Enfield action.]]> Reloading Methodology janfred https://systemz.online/reloading-methodology/safe-chamber-pressure-303-epps-improved/#post-4911 https://systemz.online/reloading-methodology/safe-chamber-pressure-303-epps-improved/#post-646 Tue, 23 Jul 2024 14:47:58 +0000 I am certain 60 000 PSI will be safe,56-57 000 psi a good not to hard on weapon pressure, but would like some confirmation.
67 000 pops the primers out, I somehow know this.]]> Reloading Methodology Treeman https://systemz.online/reloading-methodology/safe-chamber-pressure-303-epps-improved/#post-646
