    I haven't used the 30 cal J40's , but I have used the .284, 140, J36. These bullets should perform as advertised, but pay attention to the twist required. These are very long bullets and Warren told me that the 210 would not stabalize under about 3100 fps in a 1-10" barrel even at my 4200 ft of elevation. I hope this helps. You can always just give Warren a call, and he will help you out.

    Does anyone have any experience shooting LR bullets? I am expecially interested in the 168 grn, 190 grn, 200, and 220 grn J40's. Do they perform as advertised? Are their Ballistic Coefficients really what they claim?

    I want to try the 168 grn in my .308 win with a 24 inch schnider 1 in 12 twist barrel.

    I want to try the 190,200,220 grn in a 300 WSM, with a 26 inch 1 in 10 twist, will these fit in the 300 WSM? or are they too long?
