Remington 700 Ultimate

[MikePal]

As with the orignial 700ml, Remington isn't advising the use of smokeless powders for the new version.

With a barrel designed to handle 200 gr of powder, it sure would be capable of handling the stresses of smokeless power... however I can see where they don't want to say it will...if someone were to confuse 200 gr. of H4198 with 200 gr. of 777 powder it would be catastrophic. A Savage found out...North American's are sure a litigious bunch

Remington cannot be responsable for stupid, it's easier to have the disclaimer.
You are correct 200 grs of H4198 would be awful. I have gone as high as 73 grs of H4198 powder and a 300 gr.bullet but that's in custom remington with a .458 krieger barrel which is designed for smokeless powder

additional info:

here is the weight/volume difference for BH 209

Note: 100 grains by volume of Blackhorn 209 is 70 grains by actual weight, 120 grains by volume is 84 grains by weight, 150 grains volume = 105 grains by weight.

I see that Randy has produced an interesting ballistics graph for the Parker Match Hunter 300 gr. bullet. Even with a muzzle speed of 2125 using 136 grs (volume) of BH209 he found a 50" drop at 400 yds....that means your aiming over 4' above your target
