    I'm trying to get back into reloading and just purchased 1'000 Rainier 165 gr. RNFP bullets for 40 S&W on sale. Currently I'm out of the country on business and don't have access to my Manuals. All I can seem to find online is confusion as loading plated bullets. Right now all I have in 40 is a Glock 27 and I have a XDM 40 waiting at the FFL from Santa.

    For loading plated bullets it is usually recommended that you use cast bullet data for the same weight projectiles. If you need specific cast load data then you'll need to list what powder you're using. ;)

    Personally I look for pulled bullets which you can find as or cheaper then Rainer or Berry bullets and you don't have to worry about reduced loads and all that. Before I figured this out I loaded some Rainer 165 grain hollow points for my Kahr and XD 40 with 5.8 grains of Unique and CCI mag small pistol primers. You are supposed to use lead load data or reduce jacketed load data down 10 percent. The theory is that the plated lead bullets will shed there thin jackets if pushed to hard but some guys are pushing these plated bullets at near max loads for jacketed bullets with no problems. Like I stated my foray with plated was short and I am happy loading pulled bullets at moderate powder levels with no worries.

    Thanks, I'm currently in Sri Lanka on business and we just moved to the new house on top of that. I'll have to see what I still have when I get back to Fort Worth. I'm open to suggestions though.

    Rainier bullets are sized same as jacketed bullets and I have used lead/jacketed load data in the past and depending on the bullet/weight, obtained better accuracy with mid-to-high range jacketed load data but this is what Rainier has to say - http://www.rainierballistics.com/loaddata.htm
    Caution: Lyman #49 load data for 40S&W was tested using .401" groove diameter test barrel. If you are using .400" groove diameter factory/aftermarket barrel, exercise caution and consider referencing powder manufacturers' load data.

    Also, consider this caution from Hodgdon when loading for 40S&W:
    Lyman #49 load data - 4" barrel, 1:16 twist, Winchester SP primer:
    165 gr Speer TMJ W231 OAL 1.120" Start 5.2 gr (937 fps) - Max 5.8 gr (1050 fps )

    Hodgdon load data - 4" barrel, 1:16 twist, Winchester SP primer:

    165 gr Sierra JHP W231 OAL 1.125" Start 4.8 gr (946 fps ) - Max 5.3 gr (1001 fps)

    Lyman #49 has load data for 165 gr TMJ Speer plated bullet but on page 362 lists the 4" Universal Receiver's groove diameter as .401" instead of the typical .400" for 40 caliber barrels. Lyman #49 load data for W231 shows higher powder charges than Hodgdon jacketed load data and that's probably due to more high pressure gas leakage around the bullet ;). Although Lyman #49 has load data for 165 gr TMJ plated bullet, I have used Hodgdon's start-to-mid range jacketed load data for .400" diameter plated bullets (Rainier, PowerBond, X-Treme) with .400" groove diameter Glock/M&P factory barrels and Lone Wolf aftermarket barrels. For .401" diameter Berry's plated bullets, I have used lower powder charges. YMMV

    So, I suggest you slug your barrel to determine the groove diameter before using the higher Lyman #49 load data.

    Be safe.

    I shoot 155 grn Rainier with 6.5 grns of Unique in my XD. It is very accurate.

    Rainier 165 gr. RNFP

    That is my preferred bullet for IDPA bullet. I use 5gr of Tightgroup and a magnum primer with this. The velocity through my S&W M&P40 is 1019fps. Although this is a fair bit over the required power factor for SSP in IDPA, the recoil is OK with me.

    Happy shooting

    I use 5.2 gr of universal clays with 165 rainiers and 5.7 gr for 155 rainiers, work great in my S&W and witness silver team
