303, 200 grain cast bullet

[loogie33]

I am wondering if anyone has any experience loading these? the bullet diameter that i bought is .313, I have been looking for loads with these bullets using h4350 as i have 2 lbs of this and would like to use it. i found one reciepe using a 220 grain cast bullet and 41 grains of powder. will this be ok for a 200 grain?

any info would be appreciated.

Thanks

Should be, will be, if the original load is OK.

Go to the Cast Boolit Forum here:

http://castboolits.gunloads.com/

There is lots of info there and even more guys who shoot cast out of their LE all the time. I haven't used that powder so I am not much help. Pose the question there and you will soon get your answer.

Take Care

"...bullet diameter..." Slug the barrel to find out if .313" will be the right diameter, first. A cast bullet should be 1 thou over the barrel diameter.
This data is for a cast 205 grain with a gas check. It'll be better than 220 grain data.
