Thread: 7mmSaum test fire

Looks very promising. You got to be pleased with that result.
Like you I started with 2217 in SAUM but recently started playing around with RL23 and N560 cos sweet spot with 2217 in model 7 SAUM was down around 2880 fps (22in bbl).
Ladders with RL23 and 160TMKs 59gn - 61.5 gn at 2975fps and pressure good, no head stamp or ejector marks, bolt lift sweet, so could go a bit higher.
And ladder with 162AMAX and N560 61gn 2900fps, 61.5 2953fps faint head stamp, 62 gn stickie bolt.
So next step is shoot some groups with RL23 and try some RL26, hoping to get closer to 3000fps but anywhere north of 2950 with tight wee group would be nice.

@chainsaw Yes, 2950 and tight groups is what Im looking for.
