| Lapua brass, F210M, 140 grs NAB, 60.0 grs RL22 - no pressure sign in my rifle (work up from below), gives me about 2950 in my 22" barrel. Shoots well - during load development I averaged in the higher .5s for 3shot groups. - mike |

| POP just worked up this same load. E-mail him. I personally use 58 grains RL22 with a 150 grain bullet, but be careful, RL22 can change from lot to lot. If RL22 works well and you are very pleased with the load, buy a few pounds of RL22 from the same lot. 58 grains from one lot was the most accurate (primers started to flatten at 58), and with another lot of RL22, 56.5 was the most accurate and this is where pressure signs started to arrise with this lot. |

| I was out just yesterday shooting this load. I found that I got the best accuracy (100 yards, 3 shots, 0.45 inch group)from 61 gr of RL22 and the 140 gr. Accubond in my Remington 700 Mountain Rifle. But I moly coat my bullets and moly-prepped my bore, so take that into account, as moly coating and prepping seems to decrease friction, so you can safely go a grain or so higher than what would be max without the moly. I use Winchester brass, WLR primers, and load to an overall length of 3.35 inches. I also crimp the bullets using the Lee Factory Crimp Die. Velocity of this load in this rifle, with its 22 inch barrel, ranged from 3018 to 3046 f.p.s. |

| I haven't used RE 22, but it is said to be essentially the same powder as the old Norma 205 and later version called MRP. I think this is true, but there are undoubtedly some variations in the specs and tolerances for each designation of powder.
The Normas and RE 22 have a reputation for greater lot to lot variation than do many powders. My only advice is that you'll probably find RE 22 an excellent powder for the .270/140 combination, but don't rely too heavily on other's loads. Work up your own load carefully, and buy enough of a single lot of powder (preferably in a bulk can) to last for as long as you anticipate using that particular load. |
