Last friday I finally got my permission to exchange my Sako A3 338 to Ruger. Same evening drove to shop and got my new American Ranch. Later I installed my old 1-4x made in Germany scope on top of it. (btw that sucks, clicks are like 2" from 100m) Saturday morning it took 4 shots to adjust it about right. Recoil is there, but it's kind of short push, not really a kick like from 338wm.

Few notes about shooting:
I used Hornady Custom factory ammo with 250gr FTX bullets, and every brass is black from outside about inch from mouth. Temp was about +5C. Are those really that low on pressure, or is there somekind of weird oil on chamber which I couldn't remove properly?
That gun is LOUD with 16" barrel and break, flashing nice fox tail in dark morning. I had brake on my 338wm also, but it didn't make my head humming when shooting with thin ear cups. I'm planning to order silencer. Does anyone have any experience how much there is difference on recoil between brake and silencer?

Please try to tolerate my english, I'm not native...

Sooting is typ even with factory ammo. If you hand load you'll cut it pretty much out.

No experience with a can, but see one in my future

First time in about 15 years with factory ammo. Certainly will handload in future. Problem here is that you can't get LilGun easily. You guys use it all, so very little comes here to us in Finland. Probably need to start with Vihtavuori N110 and N120.

Tervetuloa mukaan!

This is old data. I still have the majority if a bottle of N110 in my reloading room. Back in 2010-2011, I tried it using the same charge weight as Lil Gun. It delivered similar velocity but it threw a lot of detritus downrange. It landed on my chronograph, that's why I noticed it. On the next range visit, I brought a white bed sheet and lay it down out in front of my shooting position. I discovered a lot of these granules got ejected when shooting N110. They seemed like an inert material, not unburned powder, though they were the same size granules.

If you intend to use a suppressor with N110 in the 450b, check it for buildup after a few shots before continuing.

Again, this us old data and not corroborated by other 450b reloaders.

Kiitos

Did you use mag primer and good crimp on those?

I've always used Remington 7 1/2 primers. Good and hot but not classified as an SR Mag primer. Works great with the other powders in the 450b.
I taper crimp down into the cannelure when possible approximately .474-.475 OD. With smooth side bullets I only crimp to .476 to avoid an hourglass distortion.

I'm using N110 and it's burning really clean.
I've run it from 35 to 39 grains with excellent results. 39 grains, Rem. 7-1/2 primers and Hornady 225g FTX gave me 2850 ft. lbs. Can't remember the velocity but I can post chrono results tomorrow if anyone is interested.

That's good info. Thanks! I guess c.o.l is near factory ammo?
