Re: New powder for 7mm RM?

wow I have never had a problem with RL22 that is the only powder I use for my 7mm RM. my best load is 66.5grains of RL22 in winchester brass federal 215 primers with 150grain TSX's shoots great!

Re: New powder for 7mm RM?

Okay guys.

I have had a bit of luck first up in my new T3 7mm RM Camo shooting 160gn AB's

I used the Nosler data and found their accuracy load using RE19 spot on. 61.5gn under a cci magnum in Remington cases worked well.

The third test load grouped .392 from a light sporter barrel. Awesome accuracy from a new sporter seated to mag length. The 168's need more work close to the lands.

I use lots of RE 19 in my mates 300wsm's. I always thought it was to quick and used the data more out of curiosity. sSupposedly over 3000fps but I am yet to Chrony it!

I did try H1000 and Retumbo but its early days as I really need to feed the Bergers singular

69.5 of h-4831 and a 139 horn btsp. 3278fps. deadly. the 160 is too hard. the 168 is good use re-19,re-22 , or h-4831

Ronin, what kind of velocity are you getting with the 4831 with the 168's?

Yep the 160 is a hardish bullet but works great on 2 to 300kg sambar stags.

I do use a lot of Hornady projectile in my other rifles and really like the SSt's out wide. The 130' SSt's in my buddies .270 Win T3 shoot under 1 inch at 200 yards. I just havent spent enough time with the 7mm Rm and 162n SSt's etc.
They drop medium game very quickly!
A 180gn SST from my 300wsm showed
a recovered weight of 90gn at 236 yards after smashing a lower leg and penetrating 2ft to the off side ribs of a mature sambar. Perfect performance I would say with plenty of trauma along its path.

168 Bergers are showing potentail but I need to single feed.

I am having a custom .338 Edge being built as we chat and it wont be that far away. Now thats going to be differnt!
