Shot a boat load of work ups and trials .
25-06' moved on up from 12.5 through 14.0 gr of Unique with the NOE 26-120 . It just doesn't want to play nice 1.5-2" at 50 yd high and right about 5" had a neck get really long on me , and the weigh lotted brass didn't help anything I guess I should anneal the necks as I had sooted necks and some lead blowby from the long neck . It probably would have been really bad with a case full 4064 and a jacket. I guess I'll jump up to 4831 and or change to something less coppered .......I'll get to that .
257 Roberts 90 gr with 10-11.5 gr Unique 11.0 looks pretty good. It's the Herters version of I think a 258733 . (I only saw a profile and it's out of print , pointy cast isn't cool . It was also a dismal failure in the 25-06' and well off abandoned. It looks like it'll work here after I swat a few more bugs .
Had the Marlin jamb . Otherwise the six 7.62x54 cases were a complete success single fed or in a anything that does depend on the rim thickness for feed control . I was able to push the mag born case forward and unlock the action . 9.0 Herco under a 458-201 Rapine 255 gr RNFP shot backstop rocks nicely and the first 3 did the atypical 2" at 50 yd and 3-4" at 100 for this example which I find satisfactory for a lower cost lever gun . 1895 G of 2010 , Marlin receiver and barrel with Rem parts and wood .
The 358 Win was a bit of a disappointment but they tend to do that first time out with new everything. I think the 360-228 needs to be driven harder than 10&11 gr of Unique. The 35-250 remains solid and shot the expected half dollar group with 44.5 4350 at , assuming nothing has changed, 2100 fps MV.
The Savage 110 in 275 Rigby did not give me the desired results with the softer alloys in the 7mm-168 but with 40-41.5 gr of H4831 it did show a definite trend towards smaller groups . I think that driving the 260-120 harder in the 25-06' is going to do the same thing whatever it is specifically that it's doing. The pleased over all with the results especially since there was fouling with jacketed 175 data for the bullets at 178 gr seating is long but there's lots of room in the mag . The matched brass did make a difference. I have to work on sizing while it has a zero over length and HS chamber it seems that it doesn't agree with the sizers about shoulder and body dimensions. I should have a 284 Win die for neck sizing shortly . Because a set came up for sale for less than I can buy bushings , a correct neck , or 7-08 die .
It's in an awkward place of how much softer and launch pliable can I go and not blow up in the twist . The 7mm is 9.5 I think Dad's 25 is a 1-12 it has never shot jacketed 120s even the FB RN but shot the FB 115 Nosler and Sierra's well . I think the controlled movement in the with the mild launch and relatively flat acceleration is what is both making it happen and keeping it from happening. There's too much case in the 25 to go to 4350 but it might the ticket in the 7×57 or it might be too fast both in the case and at the muzzle .
I'm pleased with the 92 in 45 Colts . I shot the assorted charge's of Herco under the Bear Creek 300 gr TC . The first 2 loads at 7.5&8 gr were dirty but 8.5 cleaned up nicely . These were in the slightly short very first box of PMC brass with almost 40 cycles on them annealed at about 22-24 cycles . They were loaded at 1.61" and cycled freely in the 16" M92' Rossi . This is important as I hope to one day hunt hogs with this one again and maybe shoot a 100 yd groups with it . I don't have any clue what the MV is but at 50 yd we had nice round holes spread sideways over about 3.5" and about 2" tall with all 4 loads up to 9.0 . While they hit about 2' below POH at 115ish yd (the back stop at Brushy Hollow range) . It hit in line with the sights with easy hold over within the sights , a tall dovetail post and semi buckhorn rear not quite like the intended use .
I was also able to shoot the 45 S&W S&W and it seems to be happy with the RP brass as well as the Hornady . Unfortunately it also still shoots obscenely high even with the 230s , 225-451 BB . I loaded them with the 6.0 Unique data with Herco might , I may have to just do the Unique . The stupid Hornady brass won't feed in the 92' , never seen such a fickle beast . It won't feed full length RP Colts but runs it fine short at 1.1 and the Hornady that even loaded 1.6"and 1.4" , won't feed as Schofield . In an interesting twist they shot as well as the 300s . I don't if they were cracking I didn't Chrono anything today .
