Home Forums Hunting & Shooting Ask The Gunwriters .270 Max Loads

With the RL16, I only did velocity readings.

I used to get very close to 3100 fps with 55 grains of IMR 4350.

I used to surpass 3100 fps (slightly) with 58 grains of RL 22.

Accuracy was good enough and both loads showed no signs of excessive pressure.

Rifles differ, with 55 grains IMR 4350 and 130 grain Sierra Game Kings, I only get 2990 fps.

Has anyone else tried Hodgdon Superperformance? Two people round here have tried it and got 200-300fps increase using 4831sc data as a starting point.

I used superformance with 140gr Accubonds got about 3040 fps using Win cases,WLR primers 3.340 OAL accurate load.
A more accurate load was using RL23 at about 3050 fps. with same 140gr Accubonds or 140gr Trophy Bonded Tipped.My current hunting load
uses RL23 if I,m using 140gr bullets. But if I,m using 150gr Nosler Partitions I use Norma MRP at about 3008 fps. Also a very accurate load.
I don,t use the superformance load any more because the pressure gets to high quickly.

Merry Christmas, folks. I use a .270 wcf and have for approaching 48 years now. I have always found it likes a full powder column . Have used war surplus powders in the past, newer copies of the war surplus stuff and the great new powders like RL 26...I will stick with the new developments.
The .270 wcf factory ammo and load data was dummied down , when new chamberings came into the marketplace. Just marketing.

Has anyone done chrono testing with 130 grain bullets and RL26 as I did above with Hybrid 100 and RL16?

Most that I've read say RL23 is better with the 130 class, but I haven't been able to test both yet

I cant really see you getting much more accurate info than this new data from Speer. 24 inch test barrel.

No one has mentioned IMR 4451, I have used it with Barnes TTSX 130 grains for several years with good results.
Current accuracy load is 55.2 grains at 3040-50 fps in my 24" Rem 700, but has potential for close to 3100 fps.
RL 16 was also an accurate load but not as fast, again a sample of one in my rifle.
