Why would they be hard to load?those seem to be a little hard to load
Shoot, I would buy her a boat...If she owns that boat I’m in.
Why would they be hard to load?
Oh ok I see what you mean.I haven't loaded any. One of my buddies tried to load some for a friend of his and he has a real hard time seating the Hornady FTX bullets he was using. Not like crush it from the crimp feature..like collapse the case....the issue could have been the cases...just know he hard a hard time.
Do you chamfer the inside of the case and lightly flare the case mouth?I had wanted a big bore upper for a while and last October Midway had the 450 Bushmaster 16" uppers on sale. This was the Bushmaster brand, not the AR-Stoner. I finally got around to loading some ammo this past weekend and the first bullet I attempted to seat crushed one side of the case. After that I made sure the bullet was aligned with the case and gently pulled down on the handle when seating the bullets. A few times I had to raise the handle and re-align the bullet. The expander die puts a slight chamfer on the case mouth but the bullet has to be lined up with the case. I was using Lee dies and new Starline cases. I shot a few rounds at 50 yards to get the scope sighted in and the accuracy seemed pretty good. Just passing along my experience in response to the above 450 Bushmaster statements. I attached a picture of the remainder of the loaded ammo and the components. I used Lil' Gun powder.
Oh ok I see what you mean.
I use the Hornady 4 die set.
I barely and I mean barely (like have a hard time even feeling it with fingers) flare the mouth just enough for the base of a bullet to not catch any case. I lightly chamfer inside and out also . I have not had a problem with crushing or collapsing cases and crimp to .474 at the very top of the case mouth.
I load the 225gr FTX and 250gr FTX , 245gr Spire Point and 260gr Platinum without issues.
With any new brass you need to debur and chamfer before loading.
The .450 procedure is the same as a .45 ACP.
Size, prime, slight case mouth expansion. Just enough to smoothly start your projectile in, charge the case, seat at desired length and basically taper crimp enough to remove the previous case mouth expansion.
I admit I'm no fan of rifle cartridges that headspace off the case mouth, but they're not difficult to load.
After my weekend range trip it is time to load up again. I had a good day at the range. I have been having issues with 2 rifles so I went back to some old loading just to see if it was me or the rifle. I found out it was the new loads I was using in the rifles. Since i shot up all the loads for the 6 mm and 22-250 I am at the bench this morning. Today I will be going back to trying to the Sierra 70 M.K. in the 6 mm and the 55 gr. Dogtown in the 22-250. I am trying IMR 4064 in both. We will see how they work out, at least I will get to smell the powder burn. I love the smell of burning powder in the morning.
Ahh, that is the easy part, trimming is where the heavy lifting comes into play. I would almost pay someone to do that for me.I haven’t completed any reloads today but I have decapped and cleaned a bunch of .223, .308 and 30-06 cases.

Check out little crow gunworks... I’m hooked on those trimmers. WFT2, must have five caliber inserts now.Yeah, case trimming is the worst part of the job. So I‘ve got to step up and resize and trim today.
