Started load development with the Super Grade

[ROVERT]

I started load development for the .270 using 130 BT's and RL-22. What I'm seeing so far is not nearly as promising as the what I was seeing with factory Federal ammo.

Here are the targets:

Disregard the .223 group.

I've never had anything not like Ballistic Tips. We'll see what happens as I bump the charge up a little bit. I may have to try a different powder. I may also have to mess with the seating depth. I'm right around mag length now, which has me roughly 25 thous. off the lands.

Your rifle is shooting 2 in and 1 out. It looks promosing because the group is saying she wants to shoot.
I assume you are shooting a 270 Win. Try H4831, the classic 270 Win powder and also try seating the bullet a little deeper into the case.

Like JD said, try the H4831, and CCI 200 primers.
It's a classic combinaiton.

I've heard great results from those who rebarrel their 270 Win to the .270 Improved (aka 30-06) :twisted: !!!

 

[Too Tall]

I shoot H-4831sc under 150 Partition, Fed 210 primers, W-W brass.

Give it time, just don't put loads together jumping around hoping for a lucky group. Be patient and find out what powder and bullet your rifle likes. Your initial groups are positive, they are good signs that the rifle will shoot, just take you time and work through loads.

I used H4831SC in my buddies 270 shooting a 130 gr. Partition. I worked up his load using Federal large rifle magnum primers and it sure works great.

 

[ROVERT]

Thanks for the tips, guys. I know 4831 is the .270 powder, but I'm somewhat of a powder minimalist and would rather not add another powder unless necessary. I'll try what I have first and go from there. I'm going to work through RL-22 first. If that doesn't work out, I'll try IMR 4350.

Could anyone tell me what the C.O.A.L. is for the 130 BT out of the Nosler manual?

Thanks,

Trevor

...3.340...

 

[FOTIS]

I also agree. try the h4831. Does the stock have the bubble gum hot glue bedding?

270 Winchester?

I use 55.0 grains of IMR 4350 with a BR-2 primer and the 130 gr Partition. I get about 3060 fps with a 24" barrel and groups well under MOA. The Ballistic Tips shoot really well in it also with the same load. My .270 is a Win 70 Super Grade but is 62 years old.

Below is the last 3-shot group that I bothered to bring home with this load.

 

[sask boy]

I have been using IMR 4350 for my 270 win for all of 35 years. Depending on your barrel length I would start at 53.5gr and work up slow.
I am shooter 54grs in my sons 22" BDL at 2920 and getting sub 1" MOA. Mine is a CDL with a 24" tube and I am 3054fps and 55grs of IMR 4350.
Both rifles are shooting 130 ABs. My CDL is getting .5 t0 .75 depending on how I am doing that particular day :mrgreen:

Blessings,
Dan

I know 4831 is the .270 powder

My current .270 does well with H4831, but other rifles I've worked with didn't care for it as much or were more finicky about which bullets I paired with it. These other rifles, though, loved H4350. I have no doubt IMR 4350 would work equally well.

Trevor, I think you have alot of promise there. Pick your best group so far with whatever powder charge shot the best, and start turning in the bullet a 1/4 turn on the seating stem. See if it starts to pull that last one in.

I am surprised Jim didn't mention this as he is the one that taught me the deal. It works, just have faith. I wouldn't give up on RL22 either. I know it will shoot as well as the others will. Might just have to find it sweets spot. Load up a bunch of roads varied a 1/4 turn at a time. I would bet as you work back to 3.34" you will find something pretty good. You are getting good speed already, so it is guilt edged accuracy you are looking for. If that doesn't work, bring that SG to my house and I will help! :twisted: Scotty

 

[ROVERT]

Thanks, wildgene. That's the number I was looking for.

Sorry, JD338, yes it is a .270 win.

I'm going to load up some at 60.5 and 61 grains at a variety of seating depths and see what happens.

Scotty, I think a quarter turn on my RCBS dies is about 9 thous. I'll probably load some up at 3.370, 3.360, 3.350, and 3.340.

Also, thanks for the 4350 info, guys. I'll let you know how it works out of I need to try that powder. I certainly haven't given up on the RL-22 yet though.

 

[Oldtrader3]

Most dies are 18 TPI (.056 inches) per turn.

Sounds like a great plan Trevor. I knew it had to be around .010 or so per 1/4 turn.

Charlie, so that actually works out to .014 per quarter turn, approximately. Correct me if I am way off lease.

Either way, I know for me, that is a decent way to get to the loads sweet spot. Can't wait to see what RL22 does for you Trevor. It seems like it is going to work. When is your next time to the range? Scotty

 

[Oldtrader3]

Actually I was wrong, the dies are 14 TPI (not 18 TPI)=pitch=1/14=.071 per turn. I just measured a set of my dies and .071 is correct per thread.

Thanks for the heads up Charlie. I always figured it was about .01 per quarter turn. I guess I wasn't too awfully far off? First time for everything I guess! Scotty
