I bought a bunch of these 200gr round nose plated beasts from X-treme. I have loaded their 230gr with great success. My load data for the 200gr appears to be somewhat lacking.

This is what I am looking at based off Lyman's manual

X-Treme 200Gr RN
Bulleye 5.7g
OAL 1.256
CCI 300
Mixed Headstamp brass

I am unable to locate data for this specific bullet but there is 200gr JHP and SWC data that says these numbers are good with a min OAL of 1.210. I'm not in the danger zone with my load, right? I don't think I am (because of longer OAL vs pressure) but wanted a second opinion.

You are not going break anything with that load, but you are on the high end of book data, maybe slightly over SAAMI pressure.

I have run that exact load at 1.250", no problems with my 1911's. You will likely be getting pretty close to 1000fps with a Government length barrel.

If you want a little lighter recoil, you could step I down to the high 4's and get target velocities an milder recoil.

Have fun.

Thanks. That sounds like what I am looking for. My XL650 is throwing about 5.5-5.6 actually as it sits. I will just leave it there. I have only loaded 1 to get the OAL right. I am looking forward to these. I have tons to load before next weekend.

Many plated bullet manufacturers recommend you use of Lead data or start with mid-range jacketed data.

According to Alliant, 4.6gr is Max with 200gr Lead and 5.8gr is Max for their Plated Gold Dot.

You are definitely skipping the "Start Low and Work" part if this powder/bullet combo.

Use 200gr LSWC data with an oal that runs in your gun. If you want, you can work it higher, but plated want to run between jacketed & lead.

Good thing I only loaded one. lol.

Ok, so originally I thought of loading these identical to my 230gr which is

X-Treme 230Gr RN
Bulleye 5.2g
OAL 1.256
CCI 300
Mixed Headstamp brass

This particular load is a workup I did for the 230gr and it runs very well in all my 45's.

My Lymans shows a 200gr LSWC with OAL of 1.235 and Max of 6gr Bullseye @ 909 FPS.

Hornady shows 200gr LSWC with 4.6-5.7gr @ 950FPS (for 5.7) and OAL 1.20.

It's these numbers which made me second guess my load. I quoted the JHP for OAL purposes only, I know Jacketed FPS cannot be used for lead. I did that with some 9mm rounds and had tumblers all down range and a massively leaded barrel afterwards.

If I load this 200gr the same as my 230gr above I should be lower pressure and a bit faster if my thinking is correct. I still want the load to be hot but not impractical.

It won't be impractical, just stout. More like premium SD/LE ammo recoil wise.
