7x57 prefit for my tikka T3x. Custom McGowan barrel in a heavy-ish sporter profile. Mcgowan #5 which is very similar to a bartlein #3b. 24" long. 1-8.5 twist. Stainless steel. Eventually I'll put a Bell and carlson sporter stock on it or maybe do a richards microfit frontier sportster
Currently the tikka has a 22.4" 270 winchester barrel that is rather flippy with the muzzle rise. Also the 270 barrels accuracy is just so-so. 1.5-2moa. I probably could do better than that with more load development, but i have wasted too many bullets/powder/primers already. I guess 2moa would be fine if this was a rifle I was planning on hunting under 250 yards with, but that's what my 308 tikka is for. So having those two faults, accuracy and muzzle flip, I figured let's put a 7x57 on the receiver. Much better cast bullet selection for the 7mms.
I already have the Noe 173 FN. Should be a good bullet for the barrel. I also have lyman 287346. However, that mold throws undersized bullets like crazy. I size them down to 284 and the gas checks still rotate/wiggle on the shanks. No idea why that's happening. Maybe I just dropped a bad batch of the bullets
I need to get some more brass and possibly an RCBS 7mm mold. Looking forward to this project...
8 weeks wait for the barrel, but that will go by way too fast with the holidays coming
