QUARTER BORE SST??

Has anyone done load testing with H4350 and those powder classes? Throwing a130 plus class bullet?

I've shot a ton of 135 grain Bergers and H4350 in my 25 CM. 41.5g in a 28" barrel and a 205m or CCI450 primer. Performance has been awesome and super consistent. Just under 2,900 FPS and ES has been literally 0 on some tests but averages single digit all day. The hornady 134 ELD-M has essentially the same velocity as the 135 Berger though I've not tested it consistently.

I shoot H1000 in my 25 SST but that's with a 133 grain berger. Its in an ultralight hunting rifle but ES is nowhere near what the 25 CM.

Thanks for the reply. I have shot a 25-06 growing up, so I'm building a 25 SST for the family. Ordered a 20" carbon barrel from PBB, Peak 44 stock, Defiance AnTi, titanium brake, TT Special. Excited to see what this this is going to do. I have a a lot of H-1000 and Retumbo. Suppose I should stay in the same circle as what working for everyone else.
 
Just ordered a 25 SST barrel last week from preferred barrel blanks... Will see how it is.

18" sporter (#2 I believe). Plan to run it suppressed, probably with Hornady eldm's, on my TL-3. Very much looking forward to it.

Plan is to put it into a manners PH stock for a lightweight, short, suppressed hunting rig.
 
Also shot 3 pigs with my 25 SST last night. All 150-250 lbs. The only one that ran a little bit was walking quartering away at 150 yds and shot him just behind the shoulder.
 
42.2gr N555 in 25cm sends a 135 elite at 2860 from my 28" match barrel.
I use H4350 in the 25CM. I shoot the 135 Bergers in the Creedmoor w a 205m or 450 if it's cold. 28" barrel and velocity a hair under 2,900. It is a tac driver and probably my most accurate gun at the moment. Several groups @ 100 in the .0s. I love it. I use H4350 in anything Creedmoor as it's just the easy button for me. 41.5 g and a slight jump.
 
I have been using Blackjack 131"s in my 257 AI, worked up to 46 grn of AR2209 ( H4350 ) just on the 2800fps out of a 30 inch Maddco 1:8, shoots very well at 300yds, more work required for longer range, only went to 46 grn at the time as I was working blind and couldn't find that much data at the time
 
I'm about to order dies off the Sherman website. Is the difference in the 25SST/ and 25SST B the dies for a bushing?
Yes, there is a difference. Essentially ADG changed dimensions on the Brass and required new reamers and new dies.
