Re: Power Pro 300 MP Load Data

I did not get that he was talking about the faster powders. What did I miss? I agree that sub/super results do not necessarily correlate either, but I think it's more likely there will be air space with subs. So, regarding consideration of load density, what have your observations been relevant to ...

Re: Power Pro 300 MP Load Data

I would agree 100% that CAUTION should be exercised in all reloading and even more so when using a powder such as 300-MP. As there is NO published data to rely upon, and Alliant is not interested in doing the R&D for the 300 Blackout. So if you venture down this trail, you are travelling alone for t...

Re: Power Pro 300 MP Load Data

Had some time to burn some powder today!! Had some 150's loaded up.....to test function. Kind of guessing on whats best on COAL based on how the 147fmjbt did. Hornady 150 interlock (BT), COAL 2.120 to 2.140, from 15.0 gns to 17.5 gns. Velocity was in the mid 1700's on the low end and the high 1900'...

Re: Power Pro 300 MP Load Data

Got back out today, for a little shooting. Temperature was up to 72. Kind of windy but wanted to shoot!! Took the old (by now) standard load of the 147fmjbt, modified mixed cases loaded with 17.5 gns of 300-MP velocity was up a tad from when the temps were lower to a average of 2027fps. Got a chance...

Re: Power Pro 300 MP Load Data

Read my post about 3 above yours.......although I have not ventured in the 150gn much, the 147gn give every indication you can use 150's with this powder. I have shot 150 corelokts at 16.5 and 17.0 without pressure signs. The 17.0 was more accurate. I was just focusing more on the 147gn. right now. ...

Re: harbor freight cutoff tool

I picked up a HF #42307 on Thursday. Just happened to call after their truck arrived and got my hands on it quickly. They offered the replacement warranty on it so you would think its just a supply problem.

Re: Using 7.62x39 bullets for reloading

this has been covered many times. some swage the projectile down to 308 but it is not needed. copper and lead are very soft and there are no issues. I may be late to the 300 BO, but not to reloading. While copper and lead are soft, the majority of com bloc 7.62 X 39's projectiles are copper flashed...
