Home Forums Hunting & Shooting General Big Game No experience with .257 Roberts.

Try H-100V with the 100 gr. TTSX (or E-Tip). Velocity is into 25-06 territory without excessive pressure. And out of my 24" Brux, great accuracy. This combo is a real killer. Note COAL longer than SA 2.8". This a 700 LA, so no problem with 2.9+" COAL. The throat is also longer.

IMO, the optimal action length for the Roberts, Swede. 7x57 and similar would be 3". The 3.4" LA is a bit excessive for the Roberts, but was set up so well, I can place rounds anywhere in the box mag and they feed smooth as silk. In fact, this is one of the slickest feeding rifle I have. It's all in the skill of the smith. This rifle was put together some years ago by Ronald Lampert, MN, a master smith.

H-100V is sort of a niche powder, not the most temp stable, but very efficient and clean burning. Where I hunt, temp stability isn't critical.
