Ranger66, you have choosen a wonderful bullet which will do superior work for you, but please consider a better suited powder for that cartridge/bullet combination. I have had super accurac with velocity using IMR 4831, or R22 in the quanities mentioned above. But I would caution you that since each rifle has it's own preferences ad tolerances... work up to the heavy charges. Also your COL is going to be determined by the magizine length, not how the barrel was throated, that's unfortnate. My loads are being shot in a Ruger 1B with a 26" barrel, using Federal 210 match primers and Winchester brass. The velocities are 3030, and 3050 ft/sec's. This is a very accurate bullet at these velocities for me. Now the good part, I have had a chance to field est on game, and was awed by the performance. You have choosen wisely, now go out and kill a bi buck.

These velocties sound very high, no doubt most of these are using barrelslonger than the standard 22" tube. To achieve much over 2850 with a 140 grain Ballistic Tip or Accubond in a standard 22" barrel, the pressures would have to be dangerously high. I think there may be other threads on this somewhere here on the forum. At any rate, Magpro is also a good choice for the .270 Win from what I've read in other forums. My favorite load was always a 140 Ballistic tip and a good load of IMR4350. Always .5 MOA in my 700.

A few more details on the 140 Accubond, 60.0grs of RL-22 Load.
First of all it is a Max load, and is over the max listed in some manuals.

Swift #1 lists 59.5 for their 140gr A-Frame
Hornady #6 lists 59.7 for their SST and BTSP

The Data I was working from was the Alliant data that list 60.0 for a Sierra SBT with a minimum OAL of 3.28.

Normal Max cartridge overall length is 3.340 (per Hornady)

Plugging the numbers into "Quickload" suggest pressures of around 60,290psi (with a 140 Ballistic Tip) with the normal max overall length of 3.340, and then using an OAL of 3.390 it suggests pressures of 58,638 and a velocity of 3059 in the 24" barrel which is spot on and a velocity of 2909 with a 20" barrel which is a little low.

In my 24" barreled Berretta Mato, seated .005 off the lands allows for an OAL longer than normal maximum at 3.390. Average velocity is about 3050 FPS.

My 20" Sako Finnlite also allows a longer than normal OAL, and this load gives an average velocity of about 2966.

So my experience and research indicated exactly what a earlier poster has suggested, yes is is a warm load maybe too hot for some rifles and COAL might be important. But it is a recommended load from the powder manufacturer and very close to some others. I have read John Barsness were he said that RL-22 is engineered to work best at maximum pressures, and this may contribute to why this load has shot well for several shooters.
If you have to use a shorter overall length 58 or 59grs may be a more realistic maximum. And please work up slowly and be careful. Good Shooting........DJ
