View Full Version : Another question about diff bullets

08-29-2005, 09:36 PM
I see you folks are going heavier.. what about lighter. I mean whats the stats around using rounds like the 22 Mag, 220 swift, 221 Fireball or the 22 Jat Mag. I mean I am new to this what are the diff's about these rounds. I know some are heavier and in the 40gr range but factory rounds are in the low 30's gr range. I thought using a lighter bullet would let her fly truer are straighter. So like i said why go heavier when 30 and up grains are avail?

The PS90 is going to be a PDW for me, not a plinker, truck gun, or conversation piece.

Well for me, if the round is primarily doing its damage by tumbling I want a long as possible bullet tumbling in the target. Heavier bullet = longer bullet. Also compared to lighter, shorter bullets, longer heavier bullets will be less stable and tumble after penetrating a shorter depth.
Given the same energy levels, heavier bullets tend to penetrate deeper.

In my opinion, to match the terminal effects of the ss190 we will need a bullet of similar length which places the bullet in the 55gr. to 62gr. range.

What I would like to see performance wise out of the PS90 is a load that:

1. Generates 400+ foot pounds energy.
2. Penetrates at least 8" and ideally less than 12".
3. Tumbles or expands in less than 4" of water.
4. Capable of less than 4" circle at 50 yards.

I want a bullet that produces its maximum wound profile between 3" and 8" of depth, dumps all its energy in the target, and does not exit the target.

Part of my reason for leaning towards heavier bullets is my experience hunting with the .223. Light bullets often fragment and fail to penetrate sufficiently. My favorite .223 bullet is the 64gr Winchester Power Point. I have had great success with this bullet and never seen it fail to perform. It is accurate, expands reliably, penetrates, and holds together.

Try the sierra Gameking


my understanding it is the same load in the ss193 subsonic. So should load well to the faster velocity.

Waiting on dies and time to load a few rounds myself.

well i just reicieved a box of seirra varminters 40 graon hollow points, going to load some of those, But the biggest problem is finding the light bullets, berger makes a 30 grain, but are hard to find
