270 Allen Mag users, got a question

[Derek M.]

With the 169.5 wildcat bullet and WC872, what is the powder charge you settled on in your rifle and what was seating depth? Thanks, just trying to see how mine compares.

wow, 52 views and not one response?

Well, hell.......

I'd respond but...........

I don't have any WC872 and ran out of 169.5s years ago..............

Plus my chamber/throat was one of the first and is very likely different than yours.........


I used something like 96+ of US860 and got 3400 but backed off to 3350. I now run the 140 NAB at 3640. Its a bit of a brick way out there and not enough for elk but she sure is accurate except for windage.

Sorry I'm not much help.

Thank you. I bought 16 pounds of 872 so I shouldn't run out any time soon. I think I bought 500 of the 169.5s and haven't even shot the first box yet.

I shot up to 96 and 97 gr of US869 today at 26 degrees and both of those charges were going into the same hole where the bullet was seated 15 thousandths off lands. The 872 is safe up to 99 grains with todays temps.

As far as the throat on my rifle, I did send it back to Kirby when he got a new reamer or something and he reworked it. I do not remember the details.

Just curious, but why do you say the 140 NAB isn't enough for elk? The 140 VLD from a 6.5x284 is. The 105 VLD from a 243AI has killed elk out to 1000 yards according to an outfitter I spoke with recently.

98 GR and .012 of the lands is my recipe at 3260 fps with 30 in barrel

Did you happen to safely get more powder in the case? I have had 99.0 gr without any pressure signs but have not gone higher. Thanks for the response.

So the outfitter(or anyone) thinks shooting elk at 1000 with a 243AI is OK? Sorry to divert the thread but you started it...haha
