| Buddy of mine loaded me some loads for my M1A. 147 gr. bullets over 44, 44.4 and 46 gr. of IMR 4064 and CCI #34 primers in Win. commercial brass. What say ye? I'm trying to tweek more accuracy out of my Bush Rifle but want to be safe, too. Any suggestions? TIA as always. |

45 grains is list as max load with the 150 grain bullet in the IMR data. www.imrpowder.com/pdf/IMR_rifle.pdf 308 WINCHESTER REM. CASE; FED. 210 PR NOSLER 150 GR. BALLISTIC TIP .308" DIA.; 24" BBL.; 2.755" C.O.L. IMR 3031 42.5 2750 57000 IMR 4064 45.0c 2840 58000 IMR 4895 45.5 2880 59000 IMR 4320 45.8 2830 59000 |

Go ask your buddy what data he was using for these loads. Could be that he has data specific for the rem cases and the CCI primers that shows the 46 grain load as being safe (still think that it is over the top or a max load). As for what the loads are for, haven't a clue since you should always reduce the powder 10% and slowly work up the loads in the rifle looking for signs of overpressure, and accuracy. |
| yup.. too hot for me too.. I usually use 42.0gr of H4895, IMR4895, of IMR4064 with the 147gr FMJ bullet...especially if it is for blasting and plinking purposes.. there is no need for your loads to be at max or above.. just makes for more wear and tear on you and your rifle.. not to mention your pocket book because of the extra powder you are using..... |
