.338-.270 HGT??'s

[RustyPin]

Who has pushed the Improved 06 & 270 .338's? I'm considering one for High BC 250's & 260's Grainers. What can this Cartridge Theory do under 800 Meters? 338 Bullets just have so many options available it's got me curious.

apparently it can work. an internet search of 338 sherman brings up a few good forum threads. i like a few things about the sherman cartridges, long and short. haven't shot any yet. they seem well thought out, though. long necks and 40 degree shoulders are two things i like for my own reasons.

anyway, sherman uses the 270/280 case to get that little extra length. they use all of it pushing the 250's.

sorry i don't have personal experience with a 338-270/280 imp. i do have considerable interest in it, though, as well as 338 federal for shorter applications.

I would just use the .338 win since you are already using the long action. Your 06 case is a little small for heavy 338 bullets. Would be better if you were interested in the 200-210 range.

I dunno boggs, there is a considerable following for the .338 Federal & .35 Whelen. You have to admit Hand loads on HGT could eclipse factory Win Mag loads. There's just not really a need for a Magnum.

Might I add, Load data.com lists a Sierra 250 Grain using W-275 @ 2702

Have not seen that data. Agree, a 250 at 2700 is plently.good enough

What is the case capacity of the .338 Sherman?

Fired Norma cases average 77.0 grains from my 338 Sherman.

That explains it. That is a lot of capacity. Much more than I thought.

Herbert Troester Wrote an article about a Cartridge he developed in August 1981 for a Magazine. It comes up on Google Searches, but for how long nobody knows. Modern Powders should do wonders for his Design.
