    Default Powder type for 325 WSM 220gr Loads?

    Just wanted some opinions on what powder type I should try along with the IMR-4831 for the 220gr Swift A-Frame's I just bought. I thought of RL-22 or RL-19 but wanted to see what everyone else thought.Anyone else have any loading experience with the 325? Thanks-Tim

    I just bought some of the new IMR 4007 SSC which is supposed to be a good choice for short mags. They finally got it in at SW here in Fairbanks. I'll be loading up some 220gr Gamekings for starters and to get my feet wet handloading. IMR load data says starting load is 58gr, 2626fps, 51300psi. Max load 61.7gr, 2778 fps, 60,900psi. 24inch barrel, 1:10 twist. WLRM primer. check out the IMR website. http://www.imrpowder.com/

    2700+ fps with a 220gr 8mm bullet ought to be great round I would think.

    Tim,

    Rl-19 and H4350 would probably be your best bet for the 325 and 220's. Your highest velocity will likely be with IMR4831 and RL-19. We'll wait on Perry's assesment of 4007.

    Perry,

    Yes, I think so. I'm anxious to try this powder also. I don't have a 325 now (sniff) so I guess I'll have to invent a new wildie for it. I think it lies between IMR4064 and IMR4350 in burning rate, a good rate for the not-so-much-capacity cases such as the WSM's and the RSAUM's when using heavier (longer) bullets. Let us know how that goes.
    Is there nothing so sacred on this earth that you aren't willing to kill or die for?

    Default .325 WSM loading

    I loaded some rounds for a friend of mine who owns a Browning A-Bolt in .325 WSM. After seeing that it prefered the 220 grn factory loads, I loaded up some different loads for him. The most accurate was 68 grains of R-19 pushing a 200 grain Nosler Part. I have some 220 grain Swift A Frames to try next. IMR 4350 also worked well, but the R-19 produced tighter groups for his gun.

    Default Reload info from Barnes for 200gr TSX in .325 WSM

    I called Barnes this morning and asked about loads for the TSX in 200 gr. for the .325 WSM and they ( I believe he said his name is Dave ) said the only data presently is a maximum 67 gr of R-19 for a velocity of 2825. He said more data is to be released in January '08 for the TSX. He also said not to use loads for the XLC bullet substituted for a TSX of the same weight since pressures behave differently for the two bullets.

    Default 325 WSM powder

    I've been using IMR4350 for initial trials in the 220gr loads. I picked up some H4831 too and plan on using that next. I am really looking forward to any reports on the 4007 though. From what they say it should be pretty good.
