I have yet to test but I suspect the 4198s will be perfect with 30gn bullets.
I have now got hold of Lovex D063 (or old Accurate Arms 1680) which I suspect will give fast velocities more safely. Wilson & Wilson Fieldsports in Manston has some. Also Brock & Norris was recently very helpful getting some to a shooting buddy.
In the future I may decide on one powder/bullet/weight but H4198 looks a good compromise at the moment. Haven't been to Wilsons yet but I will soon. It's only forty minutes from me. Van's in the shop at the moment though so will have to wait a bit. Newly passed Granddaughter thinks that's a loooooong way away but I'm working on her.
