I just bumped the charge on some 45 Colt loads. I feel like this Berry's hybrid bullet is on the level with their dedicated Colt bullet in 250gr. Even though it's a 45 auto projectile they've mostly measured at .4515" and wanted to shave when seated in ACP loads. So easy solution...load em for the six guns! Here are targets from a Ruger SBH hunter tested at 12 yards. The new charge is 8.8gr unique and I feel like it tightens a little with speed. We will see soon. The left side target was at 8.5gr, middle 8.1 w/250gr(berry's advertised Colt bullet) the last 8.3gr unique.
I've never had any Nitro 100 to try but I've been pleased with blue dot and unique so never looked for anything else. I also had better SDs with titegroup but was always irked by that tiny charge on those big cases. The berry's Colt bullets are good shooters. They've done well in all my single actions as well as a Rossi lever gun. Those are all 10 shot groups. I had some charge variations that threw a few but overall decent loads.
Fireformed some 7-30 cases from 30-30. These 100 gr. hp seem to be pretty accurate, They might end up being my go to round as well. Not sure if I will also load some 145 gr. grand slams I recently acquired. Too many choices since I got this contender with 7 TCU and 7-30 waters barrels. I also have some 139 gr Hornady's. I think I will save them for the TCU.
I finally got back out to the range with my 7-08 and was able to test some loads. Found one that grouped well. Now I have a reason to get back on the garage to load some up.
So finally found the right formula and technique to load .357 sig without worring about setback. I was probably being way to anal about them since I even got new ammo to setback significantly. End the end, went with .357 coated bullets with very little flare to get really nice neck tension. Little to no setback after 5 chamber loadings. Shot them today and felt good with the workups too.
