| 30 YEARS AGO Speer made a 170 grain round nose bullet for the 270. I loaded 56.0 grains of H-4831 behind it and 58.0 grains for the 130 and 150 grainers. I know that it is probablly TOO HOT for today's powder. |

| The 160 NP is in my mind one of the finest 270 caliber bullets going. In my rifle I'm using 55 gr RL-22 for a chrono'd velocity of 2850 fps. Three shot groups are clover leaf at 100 yds. With a BC of .435 this bullet is no slouch for long range shots and with the semi-spitzer front end it should be very effective. 130 NBT or Sierra BT using 57.5 gr of RL-22 for 3100 fps and 56 gr with 150 NBT = 2950 fps. I tried the 130 Hornady SST but groups with RL-22 and SC4831 have been poor - mostly because I have a long throat in this Custom 98 Mauser and the 130's can't be seated out far enough - so Hornady tells me. I used sc 4831 from the beginning but RL-22 took the accuracy and velocity to another level using WLR primers. Note: velocity reading for this rifle are high for the loads I listed in most manuals - my rifle will loosen up primer pockets with maximum loads listed in same manuals - so - be careful and have fun. |

| Just realized the N160 you were referring to is powder - oops - but try them 160 gr Nosler Partitions. |

| Thanks for the bullet & powder suggestions. Gonna give several .277 bullets a try with the suggested RL22 and see what happens over the 35P. I'll report back here on findings. Will be 'uniforming necks' with a 'Pumpkin' set up, after neck sizing. The first trip to the range will be using new full-lenth sized brass for fire forming.

| I've been loading for the .270 for a long time, and I think you will save yourself a lot of trouble if you start with H4831. Loads developed with that powder shoot well in nearly all 270s, and usually the full-house loads, too. My pet 270 likes 62gr of the stuff behind a Hornady SP seated to the max length for my action. The long seating depth means more capacity than usual--that load would be too hot in many other rifles, so approach with care. In my rifle (24" barrel) I get about 3150fps.
In the unlikely event I couldn't get satisfaction from H4831, I would try IMR4350, RL22 and RL19, probably in that order. Lots of people get good results with 150gr bullets and IMR4350. With lighter bullets, like the excellent Sierra 90gr HP, H380 does well but the slower powders do well also.
Have a ball. The .270 is still one of the finest cartridges money can buy. |
