If you get a fancy for light bullets in Bob try RX15. You won't believe the speed for the 75 VMAX or 85 BT.

Dan,

I have done that in my 6mm Rem. However, IMR 4064 will actually even better RL 15. Believe me I am a HUGE RL 15 fan.

4064 has actually given me 3750 fps with a 75 gr Hornady HP, but I throttle it back to 3500 to 3600. Hit a prairie dog with the 3750 load last year and what an explosion! Hit it about at a 100 yds.

Accuracy is a tight as the RL 15 loads also.

Cheers and Good shooting

I like RL-19 in my Roberts too !
But I got 150fps more speed and equal groups with H-414. With a 100 grain Hornady flat base 50 grains of RL-19 is great in my Ruger. ...tj3006

Thanks for the tip Seafire. I've been up around the 3500 fps in Bob w/ the 85 BT, 3600 with the VMAX. Always accurate. I'll try the 4064 one of these days but it'll be pressed to beat the RX15 for all around 'neato'. Anyway, they do make a mess at those speeds don't they?

Dan,

NO question of RL 15 hitting high on the "NEATO" SCALE.

If the local store is out of 4064, or I am too lazy to go down and get some, the RL 15 is substituted and I never worry one EyeOTA about it.

I can NEVER have enough IMR 4064, IMR 4895, RL 15 or RL 7 sitting in the gun cabinet. Or IMR 3031 and IMR 4198 for that matter.!

Cheers and Good shooting

I recommend 4064 for the 75's also in the Roberts

I've never been a big fan of Reloder-19 but have to admit that it produces a terrific group in my 6.5x55 Remington Classic with the Hornady 129gr. bullet. I'll have to look a little harder at the other Reloder powders. I may have been missing something here. Best wishes.
