Let’s see those Smokeless builds!!

[Coldfinger]

Beautiful awesome job.

I actually did better at 400 than 300. I was having trouble concentrating on my poa as my sharpie marker was dry and left very faint almost invisible circle. 300 was about 2.75" perfectly horizontally. That was with 81 grains of 4198 and Fed GMM lrp Parker 275 grain bm

Way to go. Absolutely fantastic.

I'll be taking my McWhorter out very soon. Want to finalize my load

Here is our new muzzy build, built by Eric at blue mountain precision.
It'll be going to New Mexico for an elk hunt in couple weeks. It'll be running a revic iron sight.

 

[6.5x300 WBY]

Awesome well done

 

[6.5x300 WBY]

Well had to join in and took my McWhorter 45XML out. 90gr 10x 303HC pittmans fed 215.
Check that SD and ES. In the .2's. Iowa here I come

 

[6.5x300 WBY]

This was first 6 shots and how it went.

Those 3 shots were made after a slight scope adjustment if anyone was wondering why a change of impact.

Looking great!! I always wonder if we take cold bore shot the wrong way. Is it cold bore dynamics or cold shoulder dynamics? Probably need a laboratory to actually find out. Seems like I get better as I shoot. Or is it the gun?

Cold bore for me was that I just haven't shot this gun in weeks. Temp was about 60°. So my cold bore was just first shot.

Finally got the new front stuffer sighted in! Mesa action, Brux barrel cut to 23.5", Hankins plug and Greyboe stock

275gr Furys pushed by IMR4198. 2808fps avg. 5 shots at 100 yards

 

[6.5x300 WBY]

Sweet build. Congrats. Looks like you are ready

How do you find pressure in a smokeless? I'm new to it and my smokeless will be here in 2 weeks roughly. i know my smith has some known loads which is obviously where I'll start but let's say you try a new powder. I'd asaume an under charge of a muzzleloader is fine as long as the slug leaves the muzzle, but how do you determine your max charges? I'm so use to finding max on my rifles through reading the brass but I can't seem to find out how I'm suppose find max on a smokeless

What I do, and I think most others do, is go by the builder/designer's recommendations. Like for Arrowhead, Luke recommends 80gr H322 in a bolt gun and 60gr IMR4198 in the Encore barrel. I just stick with what Luke says. The gun doesn't blow up, and the performance is tops. For my Savage MLII rifles, Savage had a list of approved powders and charges, and a list of powders to avoid. I run 44gr 5744 in that one.

Smokeless MLs are not really a great place to do a lot of experimenting with powders. Stick with your builder's known loads.

Okay but here's my thing. Luke recommends 80gr of h322 which is great. But what if that doesn't shoot worth a ****. Do you move up in .5 gr increments, full grain, move down. When is too much and too little pressure. That's the part I don't understand. I fully intend to stick with what my builder recommends which most likely is what Luke recommends as he uses arrowheads stuff and recommmeds h322.
