components used:
speer 270gr projectile
65gr of 2208 powder
current speed through chrono is 2488 to 2498
theres no cratering on the primer or serious flattening it still has rounded edges does anyone know how hard you can push this cartridge with 2208 or should i try a different powder people have gone as far as 69gr of 2208 but i dont feel safe doing this as i dont feel like having it blow up or hurt someone else.

hey blade you should try shooting 2206 in a 375h&h, smacks you like tyson
nightforcenxs wrote:hey blade i never went past 65 grains of 2208 this load is stated as max from ADI load data reason im going for 2600fps with the 270 everyone that has shown groups have found the speers to group good at that speed some guy shot a 3 shot group at 100m under .3 of a inch i shot 20 shots off the bench with out a sore shoulder so its not kicking or punching like tyson
thansk for the info Ten ill slowly move it up how did you find case life at that much grains of 2208 im using the ruger no 1 and was told by a RO that he gets more fps easily with 300gr pills ill move up in the 1/2 grain and chrono each one if 2208 fails to do its job ill try 2209 and also reloader 15
nightforcenxs wrote:i understand what your saying about how some powders dont give much more velocity once there at max thats why im cautious about going past max with the 2208 i have a feeling its not gonna get much faster and all im gonna get is pressure signs hence why im thinking a different powder may be better if i can get a inch or even a inch and half at 100m ill be happy right now its throwing 4 inch groups on me and thats with it rested on a front rest i also have to play with the pressure that goes on the barrel under the forend if it doesnt get better because ruger no 1's have that weird pressure screw under the barrel so its gonna take awhile to get it to shoot decent

You may still need to treat them with a regular hit with bore bright to lift the finish and settle the copper fouling. It might take a hundred rounds before it is run in and settles. You should be able to get it shooting close to an inch once you sort it out. I did my farmer assist target with a 416 #1, it shot .950 much to the range officers surprise.

Nightforcenxs, for starters, I'd change powder to ADI AR-2209, it (and IMR-4350) are the recognised best powder for the .375 H&H.
FYI, I worked up to and now use the recommended Maximum powder charge of 80.0grns of AR-2209, a CCI 250 Magnum primer, under various 300grn bullets.
I can't remember the chronoed velocity at the moment, but it's in the 2500 or 2600fps range.
Hope that helps
D'oh!
