The magic place for .30's.

Using traditional bullet designs of about 200 grains, almost every full size .30 caliber likes the 1400 - 1450 f/s speed range. Not only 1/10 twist in the big cases, but 1/12 for 170's in the 30/30 and 115's in 1/20 for the 32/20. This is the first place I go when looking for accuracy in a 30 caliber.

Below is a target I shot with an original Newton in .30 USG (.30/06 in modern terminology) in the late 1990's, post front and Lyman 48 rear. It has the Pope-Newton "segmented rifling" system. Everyone who looked at the rifle thought the bore was worn out because there were no lands and grooves.

So here is one of those days when the sky is bright, wind gentle and steady and you are shooting in the groove. Ten shots at 100 yards with a 6 o'clock hold.

Can't get the picture to stay right side up? Life is hard when you are computer illiterate. Fixed that for you, Rick. :)

Looks fantastic. I'd be thrilled with a 10 shot group looking like that out of any rifle at 100 yards.

did you do any special fitment of the bullet?
or use a soft like alloy?
Alloy was 1990's WW's (96/3/1) and two percent tin, my standard plinking alloy, BHn about 11. Seated long so that first driving band was against the lead, and I could feel the bolt close. It is the same OAL with almost all my Springfields and worked for this one also.

Very nice shooting
It isn't a magic load, nor am I the world's best benchrester. But when everything in the environment is good, you are feeling chipper and concentrating, amazing things can happen. This was one of those days everything was good in the shooting world.

Ric....Some fine shooting there!
I like what you said. It is nice when you have one of those special days!

That photo of the rifling in that rifle is similar to what I'm seeing in my model 38 Japaneese. Looks like plenty of rifling but it is it very strange. I recut the crown yesterday and that told the story. Muzzle looks almost identical to your photo
