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.
It is irrelevant what you think. What matters is the TRUTH.

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.

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....,,

Hunting where I hunt, 10*-75* it's a non issue. 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. DF

About time someone started a thread on good 7mm RM loads! Here are some of mine (all from a 26 inch 1 in 9 Rock Creek barrel). Velocities measured with chronograph 15 feet from muzzle, none corrected for actual muzzle velocity (can be done with the JBM calculator, too lazy).
Bullet: Sierra 168 gr. HPBT Matchking Powder: Hodgdon H4831 63.0 grs. Primer: Federal 215 Case: Federal LOAL: 3.300 (2.742 Base to Ogive with Stoney Point) Average Velocity: 2778.28 fps ES: 22.14 SD: 9.32 Comments: Very accurate, best three shot group at 200 yards was 1.042 inches
Bullet: Nosler 160 gr. AccuBond Powder: Alliant Reloader 25 69.0 grs. Primer: Federal 215 Case: Federal LOAL: 3.323 (2.758 Base to Ogive with Stoney Point) Average Velocity: 2995.40 fps ES: 19.98 SD: 8.42 Comments: Jam length 2.778 Base to Ogive with Stoney Point. Bullets seated for 0.020 bullet jump to lands. Best three shot group at 200 yards 0.672 inches.
Bullet: Speer 160 gr. Grand Slam Powder: Alliant Reloader 25 69.0 grs. Primer: Federal 215 Case: Federal (2.119 Base To Datum Line with Stoney Point) LOAL: 3.244 (2.718 Base to Ogive with Stoney Point) Average Velocity: 2943.55 fps ES: 22.13 SD: 8.77 Comments: Jam length 2.738 Base to Ogive with Stoney Point. Bullets seated for 0.020 bullet jump to lands. Almost as accurate as previous load.
Getting good accuracy with the Nosler 160 gr. Partition but haven't chronographed the load yet and I've only tested it at 100 yards.
Bullet: Nosler 160 gr. Partition Powder: Alliant Reloader 25 68.0 grs. Primer: Federal 215 Case: Federal LOAL: 3.285 (2.745 Base to Ogive with Stoney Point) Comments: Jam length 2.755 Base to Ogive with Stoney Point. Bullets seated for 0.010 bullet jump to lands
Alliant Reloader 25 is my favorite 7mm Remington Magnum powder but I've been trying IMR-7828 too.
Bullet: Nosler 168 gr. HPBT Custom Competition Powder: IMR 7828 64.0 grs. Primer: Federal 215 Case: Remington LOAL: 3.300 (2.735 Base to Ogive with Stoney Point) Average Velocity: 2848.78 fps Extreme Spread: 21.50 Standard Deviation: 8.30 Comments: Jam length 2.755 Base to Ogive with Stoney Point. Bullets seated for 0.020 bullet jump to lands. Cases sized in Redding Type S Sizer Die with .308 insert

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!

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