I have a Rigby and Taylor and really like them both. The Rigby with handloads has no problem getting 400grs out at 2500fps. The Taylor will get them out at 2400fps but I have found that loading them 2350fps using IMR4320 lets me crimp in the groove and Doesn't show any pressure problems. I have shot it on really hot days without a hitch. I guess I can't decide between the two but if forced I will have to say the Taylor. reflex264
