My experience with 130 gr. bullets in a 270, the powder sweet spot for performance are powders are: H4350, RL-17, RL-19.
My 270 has a 24" barrel and all three of these powders deliver accuracy in my rifle and with higher velocity than H4831 generates.
If you're not getting the accuracy you are...
RL-17 makes my 270 rock with 130 gr. bullets.
You have plenty of pressure headroom to increase the amount of RL-17 and perhaps going forward you will find the magic point of power and accuracy.
I'm seeing H4350 locally for far less than that. I'm wondering if the manufacturers are having retailers "bid" on available powder and some pay elevated prices just to have something on the shelf to sell.
All this high tech....
My old school barrel bobed and suppressed 581 Remington toys with MOA accuracy off the bench at 100 yards with Norma TAC 22 subsonic on a calm day and even better with R50. Not saying this is the be all 22 rimfire, but that old rifle can stack them into a tight group...
GRT => Gordon's Reloading Tool is like Quickload, but is free and not as comprehensive.
My 416 Taylor sports a 24" barrel, but 83.6 gr of RL-17 pushing a 350 Speer GS delivers 2622 fps and 5344 fpe in my rifle.
It's a max load, and you really don't need to load it that hard to get performance in...
Greetings from another 416 Taylor owner.
GRT shows these max loads with a 25.5" barrel:
72.0 IMR 4064 2527 fps
73.0 IMR 4166 2528 fps
79.0 RS Big Game 2560 fps
If you can find some RL-17 it really makes the Taylor hum.
5.5 lbs according to a different spec sheet I found.
If you were looking for a compact rifle for a float plane, it might have a purpose.
Personally I'd opt for an additional 18 ounces and take my Rem 700 Ti in 7mm-08
When I'm shooting 150s in my 270, I use these loads:
150 Nosler LRAB 61.0 RL-26 Fed 210 Fed Case 3.492" 3084fps
150 Nosler LRAB 60.0 I7828 Fed 210 Fed Case 3.492" 3004fps
I'm gathering the dies needed to swage 30 caliber bullets to .287" for use in my Ross M1910.
I'm not getting into the bullet business, but rather just planning on helping out shooters who need fat 7mm bullets for their rifles.
Additionally if you happen to be a member of the...
