Jon, where did you hit pressure with the Peterson brass?
That is an unbeatable group as far as I am concerned ! Wouldn't change a thing ! I assume this is a heavy barreled rifle! How long and how heavy and what brand is your barrel ? I am in PA and haven't heard of Moon. Is he a gunsmith from your area ? Congratulations on the success of your new gun !
Jon, where did you hit pressure with the Peterson brass?
2970fps w/ the 230 from a 27" barrel. The 215's were running 3120fps w/ RE33. Mine is a standard Norma.What velocity were you getting with the 230's in your old rifle? I run 215's at 3100, but I have an improved version.
Nice! I run H1000 through a 26" tube. I could push it faster but it shoots too darn good to mess with it.2970fps w/ the 230 from a 27" barrel. The 215's were running 3120fps w/ RE33. Mine is a standard Norma.
Thanks for sharing your information ! And again an unbeatable 30 cal. group to me ! I am going to start filling my piggy bank ! Great looking gun !Thanks! The speed should pick up after 150-ish rounds and the barrel settles in. Here's a pic of the rifle and its specs:
Crescent Customs build (Tim "Moon" Roberts)
J. Allen Chassis (CIP length mags)
Surgeon XL
Bartlein heavy palma 1-9 twist, 27"
Area 419 Sidewinder brake
Triggertech Diamond
Thanks Eric! Was out shooting yesterday afternoon and the barrel has already sped up. The same load is now averaging 2970fps with no pressure signs. Prints 1.5" groups at 403y. Man I'm loving Peterson brass!Oooweee Jon!
That is a beautiful, tiny group. Kyle Lamb loves the .300 Norma mag. and now you know why. I have some of those Berger 230 gr. Hybrids and they work very well in my .300 Win mag. at distances to 960 yards (max range of my club's steel range).
My heavy barreled, stainless HS Precision gets groups like that too with H 1000 and Winchester primers.

The first lot of peterson brass measures 0.580 at the web, and spec is 0.583, a known problem that they are addressing with new lots. It can eventually cause over working in that area. Just an fyi to keep an eye on that.Thanks Eric! Was out shooting yesterday afternoon and the barrel has already sped up. The same load is now averaging 2970fps with no pressure signs.
