My Rem700BDL.375RUM has a 25"bbl. I use 270gn Barnes TSX.
Here's some chronographed loads - 5 shot average.
93gns H4350.......2880fps
100gns RL 19.......2904fps
90gns RL17........2895fps
100gns RL26.......2795fps
Is the action bedded and barrel free floated? If not, get it done. In my experience, range testing loads in hot weather always produce bad results, especially with factory sporter weight barrels. Try firing consecutive shots from a cold bore. When it's hot ( above 90F ) that often means...
When I looked at the Quickload data supplied by Tackdriver284 I thought my 375 Rem Ultra Mag would perform very well using RL26, especially as it appeared to be the top performer in terms of velocity. I knocked up a few loads using 270gn Barnes TSX and 100gns of Reloder 26 and tested them on...
I've never asked for a QL advice before but I'm desperately wanting data for @ 270gn Barnes TSX and Reloder 26. After plenty of searching, it appears data on this combination is non-existant.
Any help would be much appreciated.
I've never tried H335 in the 7mm/08, although I did try it in my 308 with 150gn bullets. Like others have said, muzzle flash is impressive.
By the way, I also have a 7mm/08 and of all the powders I have tried with 140gn bullets RL17 gave the best velocity.
