Re: 4895 for 7mm Remington Magnum
I would think either 4895 would be too fast for the 7 mag. I'm not saying you can't shoot it in one, but probably not the best choice out there. It also depends on what grain bullet you're pushing. I have used 64gr of Varget & 58gr of IMR 4320 in mine to launch 100gr Sierra HP's & 120gr Sierra spitzers, respectively. The accuracy was .2525" (3-shots) for the 100gr and .4015" (3-shot) for the 120's. Both used CCI BR2's. Didn't have a chronograph at the time, but I'm sure they were smoking.
That was back in 2000 when I shot those loads and alot of powder has been burnt down that tube. Since then I have mostly shot 67gr of RL22/w the 150gr Nosler Ballistic Tip and BR2's. This is a very accuracte load in my Sendero and has accounted for lots of deer, crow, fox, feral cats and any other critter/vermon I can get a bead on.
Recently, I have been doing load development with the 150gr Scirocco. It is proving to be just as accurate as the Ballistic Tip for me. I hope your 7 gives you the shooting pleasure mine gives me. Good luck. Johnny K.
