.375 Accubond 300 grain?

[taylorce1]

Saw that these bullets are available now but the site doesn't list a BC or SD for this bullet. How much better is it in the ballistics departmetn compared to the Partition? I'm interested in trying some 300 grain bullets in my Ruger.

 

[JD338]

The .375 cal 300 gr AB has a BC of .485, SD of .305, and a length of 1.520"
Nosler p/n 53662

I will be trying them in my 378 bee. 3100 fps :lol:

 

[Richracer1]

I have some for my 375RUM as well.

 

[taylorce1]

I will be trying them in my 378 bee. 3100 fps :lol:

POP I'll be happy if I get back over 2550 fps with my Ruger!

Thanks for the info JD!

 

[FOTIS]

You should get close to that.

 

[taylorce1]

POP, how close can I get? Whip out some QL data for me please. My rifle has a 24" barrel. The powders I have on the bench that I have data for this cartridge are:

RL-15
IMR & H4350
IMR & H4831
W760
H414
H380

Which powder will get me closest to my mark of 2550+?

Thanks

Thanks POP. Got what I need to start and even found a few extra choices in powders that I have that I didn't even consider.

Anytime. Start 10% below work up slow.
