Does anyone here have any pet reloading info they would like to share ???
Fixing to pick one up and was wondering what everyone else is running in theirs

[PondPopper]

For deer and may other species 110gr Accubonds.

[J.B.]

73-75 grain R25 (work up to 75.....HOT)
115 berger VLD

3500-3600 FPS from a 25-26" bbl

It will perforate 3/8" AR500 steel

Id start with large amount of retumbo and 110 accubonds.

Man, that is a screamer for sure!

i just got a 6.5-300 wby that we will start loading for soon, kinda curious on speeds in the 140 grain range

Wow!! That's nice. Does it exit? Probably not huh?

Thanks for the info ,
100-110 grain bullets is what I have been wanting to start off with .

I've shot the 100gr Sierra BT at a couple of deer. They did not exit. FYI.

But they were DRT.

I ran a 1-10 twist Bartlein with 115 VLDs @ 3400-- rebarreled to a fast twist (1-7.5) to run the long 121gr Hammers and 131 Blackjacks--

7828ssc has been consistent but slightly slower velocity (3300~) than I had originally hoped.

Because of the reduced bearing surface some guys are getting over 3400 with 131s... which puts them, energy wise, in the league of the 7RM w/ 162s...

I'll be testing the 131s on Aoudad in three weeks!

Dang.

I'm running same powder and bullet. Didn't think you could even stuff that much powder in the case

Hey that recipe looks familiar! [emoji12]

Definitely proceed with caution as it is well above book max.

And yes it will blow through 3/8 AR500 even at 200 yards.

That's crazy!!

I have used Rl22 and 100 grain NBT. I have a late friend who was very passionate about a healthy charge of H1000 and 100 grain Barnes.

Please post up how those 131's do on Aoudad.

I have always shot 110 Accubonds out of mine.
