Started load development with the Super Grade

[Oldtrader3]

Actually that is a first time wrong for me (today at least)!

I went to the range with the .280 today after changing rings for sighting back in and shot a few 3-shot groups for practice with factory ammo. The .280 always shoots any factory ammo into about MOA groups. I was shooting Federal-TBBC and Failsafe 140's today.

The old Redfield Illuminator on the A-Bolt is not as good a scope as the Minox but it still holds its own.

Charlie, that would be for bumping the shoulder back with the die. The bullet seater stem, however, is 28 tpi on RCBS dies. I know this because I recently rethreaded a Lyman die bushing to use an RCBS expander.

I did the math earlier, I'm pretty sure it comes out to around 35 thous. per turn (thread).

Scotty, I'm at the bench (reloading) now. I probably won't get back out to shoot until Saturday.

Sorry Rovert, I was thinking about backing off the die, not the seating thread. You are correct, the seating screw is 1/4-28 TPI. A quarter turn would be .009 inches.

 

[ROVERT]

No worries, Charlie. I guess it could be done either way. I always use the seater stem. The only thing you'd have to be careful with using the die body is that if you were working the seating depth down, you could end up crimping when you didn't want to.

Trevor, this is certainly a concern with the crimp ring. Many of my dies are already set with the die crimp ring just a half turn off the case neck anyway.

Man, those decimal places and fractions were kicking my butt today!

Thanks for clearing that up Trevor/Charlie. Now looking back I see the error in my math and measurements. Scotty

We engineers gotta be good for something (right, Trevor) and stick together because nobody else will stick up for us!

I've never been able to get good results with Reloder 22 and 130 gr bullets of any kind. I've got a real killer load with the 150 bt and Reloder 22. It shoots 2950 from a 22" barrel and very small groups. I've gotten consistant good velocity and groups with a 130 gr bullet with IMR-4350. H-4831sc has also been good.

 

[Oldtrader3]

I started conserving powders when Obama was elected because I could not buy anything that I needed locally and not much anywhere else. So now, I use IMR 3031, 4064, 4350 and 7828. These four powders cover everything from the .204 Ruger and .32 Spec. to the .340 Weatherby and .45-70. I stock (2) pounds each of all four powders so that I always have something to shoot.

There is only one store within 50 miles of me that carries Reloader powders consistantly and I only get down there once or twice a year. Blight Washington is not the center of the universe for reloading.

I got a quick range session in this evening. The groups were shrinking as I worked through my loads.

This is the last load I shot:

I didn't get a chance to shoot my 3.340" COAL loads, so I'll do that my next trip out. I'll also load up some more of the above load to confirm the results.

It's looking promising. Thanks, guys.

 

[hubcap]

3.350 looks pretty good. How far off the lands did that dim. put the bullet ? 8) 8)

 

[ROVERT]

The COAL with the bullet seated touching the lands is right at 3.400", so that load is 50 thous. off the lands.

 

[SJB358]

Trevor I think you have a shooter! Looks very deadly to me. What was the speed of 61grs of RL22? I would think that will handle any deer walking! Great load work, can't wait to see the verification group! Scotty

 

[hubcap]

Just noticed 3149 fps marked on the target. NICE

 

[DrMike]

Trevor,

I believe you are there. Anything after this is merely gilding the lilly.

 

[ROVERT]

Here are the last two groups I shot:

I found a little more consistency at a C.O.L. of 3.340". This rifle seems to like a clean barrel. After about 20 rounds, the groups start to grow.

61.0 gr. is the charge I've settled on.

 

[Oldtrader3]

Nice groups, it appears to me that you have reached a good, stable harmonic level with that load and the velocity is pretty high also for a .270 Win, 130 gr.

 

[SJB358]

Looks pretty good Trevor. I would say you are more than ready to hunt and you are getting some incredible speed and great accuracy out of that rifle. Scotty
