Great shooting, Tanner.

I wish I had better access to a 1K yd. shooting range. At my deer camp, there is a 1K yd. range, but it's nearly an hour from my house; takes time to travel, set up, shoot and return.

I can shoot 100 yds. behind my house.

Been using Fed 215M, Win brass, and stay .005-.010 off for the following:

168 VLD H- 71.5 Retumbo
160 AB-66.5 RL22
160 Partition-61 RL22
150 BT- 68 IMR 4831SC
140 AB-69 RL22

I reach for RL22 first every time nowadays for 140-160 pills. The usual "work up to" stuff applies, but I've found my more accurate loads have been at or near max in both of my 7's.

My favorite is:
150 BT-67 RL22

Another few more RL22 loads as well, all run through a Beta Master Chrony via my Savage 116 w/24" bbl


120gr Barnes XBT/TSX/TTSX
71.5gr___ 3.35" OAL___3450fps

120gr Nosler BT
72.5gr___3.385" OAL___3510fps

160gr Nosler AB
65gr___3.355" OAL___3000fps

Can't believe you did that.....

And especially to replace it with a......

Good grief Tanner.

Mine likes max charges of Retumbo with the 150 ballistic tip and TTSX. Used to use R22. Accuracy was there but I tired of the temp sensitivity issues.

Got some examples? Hunting where I hunt, 10*-75* it's a non issue.

Pretty good stuff, though with only 500 yards to play it looks like diminishing returns to put one together. Might just call it good with 178s/208's outta my thirty ought grandpa....,,

Not an issue with me, as where I deer hunt, 20* is cold and 60* is warm.

A pronghorn hunt in August can get pretty warm.

To the guys hunting in sub zero conditions, I understand their concern.

I see you're also an RL-25 advocate.

Me,too! ....within the last 3-4 years or so.

145 LRX
66.5 RL-22
.050 off
3,100 FPS

RL-25 is my favorite 7mm RM powder but when supplies ran low I tried IMR-7828 (Tanner's favorite) and its good too!

Come to think of it... when he was running low on IMR-7828 I thought about selling him my jug. But then I actually tried it and my greedy nature took over! Mhua, ha, ha!

Sure. My previous load with R22 my poi shifted three times from summer to early fall to late fall. Seemed I was always adjusting poi accuracy was fine but poi shift seemed constant depending on weather. It wasn't a lot, but enough I switched to Retumbo and with the same rifle have not had to adjust poi except when I changed the stock. R22 is a good powder no doubt it gave me good results and velocity, however my rifle shoots better with Retumbo without having to adjust my poi.

I have also used H414 (30 06) R19 (.243 and 300 Win) BLC2 (222 Rem) and haven't had the same issues I had in my 7mm with R22. Admittedly I have spent the most time at the bench lately with the 7 and I have gotten pretty picky. Maybe the sometimes severe summer humidity is another factor in my experience as well more likely is that the others haven't seen as much variety in conditions so I haven't been as sensitive to the sensitivity. I'm not saying R 22 is bad I'm just saying that for me Retumbo seems to work better.
