View Full Version : .303 British starting loads for 54R
April 09, 2007, 20:09
Ran across the idear of using .303 British starting loads for 7.62x54R while surfink around. Does that sound reasonable or terminally stupid? Data is more extensive for .303 British. What do you think?

I would start at the low end of .303. I have some data in 2 or 3 of my manuals. What bullet weight and powder did you have in mind?

Thanks. 123-125 gr. bullets (310-311); IMR4895, H4895, or AA2495 for powder. Going to start with those powders because they are forgiving when loading towards the low end.

You shouldn't have any problems doing that. The 303 holds a bit more than 10% less by volume than x54R.
I usually use 30-06 starting data, as their volumes and pressures are nearly identical. This practice may blow up your guns and kill you...

Found some loads for 7.62x54R on www.reloadersnest.com if it's any help.
One load is a 125gr Sierra over 50.0 grs. of H-4895 for 3036fps. More loads especially with heavier bullets.

My Sierra book has the following for 125gr:
IMR 4895 min 45.6 for 2600, max 48.7 for 2800. Other powders include IMR 3031, 4064, 4320, H380. let me know if you want any data for these.

Allrighty, thank you all. That enough to keep me busy for a while.
