IMR 700x load data

Hammer76 · January 5, 2016, 10:08 PM

I've been looking all over for load data on IMR 700x powder and they don't show any data for a 155gr. lead rnswc. Am I able to use the same load information for a lead round as a jhp, xtp or fmj round as long as the col is still at 1.12?

40s&w. I have the information for accurate and ramshot powders. I'm trying to gather as much as I can incase the powder I want isn't available. And so far I can't find accurate or ramshot without paying an additional $40 in haz-mat and shipping charges.

There is not much data for lead bullets in a 40 S&W, as you have found. I would guess at 35,000 psi, it doesnt play well with softer lead alloys? Sorry, not much help.

I have been told that plated and hard alloy loads are mostly interchangeable.

Of course start lower and work up.

My records show 155 gr Berry's flat point, which is a plated bullet, with 4.9 gr (1010 FPS 23300 PSI) to 5.5 gr (1134 FPS 32700 PSI, of 700X.
For a 155 gr Hornady XTP it shows 5.2 (1054 FPS 26600 PSI)to 5.8 (1138 FPS 33700 PSI).

If I were loading this cast lead round, I would start with 5.0 and 5.2 grains and Chrono to see what my actual FPS is. Shoot off of bags and shot for group as well.

Warning: This information is worth exactly what you paid for it!
