yup awesome round...117 gr spbt and about 52 grs of IMR4350...smokin out of my 25" barreled mauser. drops mule deer like lightning.

a buddy of mine got a SPS last year in 7mm rem and turned out to be a real shooter. did up a handload with 160's and retumbo which produced groups hovering near 1/2"...not bad for a bone stock rifle.

6.5whitetail I used 52.0 gr of IMR4350, norma brass, CCI200 primer and a 120BT...very accurate. with that being said though, i had terrible bullet failure on a mule deer...high shoulder shot at 225 yards...bullet blew up on the surface but broke the shoulder...the next shot in the lungs and he...

muzzleblast525 i have a 257 bob in a ruger #1 and love it...shoots great and is my wife's deer rifle. shoots great for a stock rifle and a #1 to boot...consistently well below MOA. my handload of choice is a 117 sierra spbt over a healthy charge of H414. Now to not start a fight with #1...

For those who have been looking for info for the 257 Roy and Retumbo, here is what i got. Weatherby brass 120 gr bullet CCI 250 primers Started at 68.0 and worked up to 72.5. I had no pressure signs at all but according to the quickload data that i had 72.5 might be running a little hot...

Maybe the 30-06...even though it does it all it's...well...just boring 25 ACP for sure

Pop i actually had that rifle built for my bro and i specified a minimum dimension chamber and 27" of barrel...the same as i did with my STW...i know that speed is crazy...just blows me away...you want to hear another funny thing...with both the 264 and STW we still have yet to trim a...

Pop I know it sounds wierd but i think the barrel is "fast"...how many grs of powder are you using? My brother and i have a couple of rifles with shilen barrels and they seem to produce more speed than stock barrels. for example my bro has a 264 winchester that spits 140 gr pills at 3500 with...

Pop i'm getting about 3300...rifle has a 27" shilen barrel

Yeayow Thanks a million for the information. When i get the results from loads i will post. Thanks again. Brad

340boy I just looked at a powder burn rate chart and found that Retumbo is just a shade slower than RL25 so i would think that you could use the RL25 data to get you started. It looks like my previous recomendation might have been a little high. i found data for RL25 starting at about 63.5...

My STW loves a 160 AB over 80 gr. of Retumbo...if i were you i would start at 75 gr. and move up from there.

My 7 STW loves the 160 AB...80 gr of Retumbo + remington cases + CCI 250 primers = 1/2" groups!

340boy Thanks for the reply...unfortunately being up here in Greenland i don't have access to one of those programs. I'm with you on Retumbo looking like a good powder for both the 270/257 Wby. I use it in my 7mm STW pushing a 160 accubond and it is a total deathray. I would assume that you...

Has anyone tried retumbo with a 120 gr bullet? Where would i start at with the powder and what would the max be? Any info would be greatly appreciated.
