How 'bout one more 150 E-Tip Quickload?

[pharmseller]

Sorry for my fascination with the E-Tip and 7mm Rem Mag, but I've been tasked by my brother to build him a load, and he brews beer. Not very good beer, mind you, but beer nonetheless.

So whilst perusing Nosler #8, I see IMR 4350 generates 3248 fps at the max charge of 63 grains. Since the E-Tip is a monometal I'd like to see what Quickload has to say.

150 E-Tip
IMR 4350
7mm Rem Mag
WLRM
Remington brass
3.260" (from the book)

Then, since everyone is raving about Reloader 22, can you use the same inputs but substitute R-22?


Thanks,


P

If you read the fine print it also says be sure to start with starting loads when using the etip.
Barnes 150 Is probably a hair slipperier than the Nosler e-tip and although they don't show i4350 as a powder they show a max of around 60 graines with i4831.
Ramshot shows a Max of around 58 with their 4350 and the 150 tip.
Doing a hillbilly cross ref of these 3 ideas I wouldn't be looking at starting more than 58 grains.

Dang, I was hoping for better velocity. How does R22 look?

[TackDriver284]

RL 22 and RL 25 / RL 26 will give more velocity. RL22 and RL25 is temp sensitive, RL26 would be a better choice if you can find the powder. Seems many people are buying them like candy. With my 7 Mag and 26 inch Brux barrel and 140 VLD I am getting 3250 to 3300 fps with RL22 and with 168 VLD and RL25 at 3,025 to 3,050 fps.
