450 bushmaster reloading issues

[Omidv]

Should send a couple cases out to someone that has dies for them to check???

I’m sending some brass with my dies to hornady. The guy said if he can’t repair my die he would give me a new one.

Gotcha, maybe not fast enough for longer projectile’s? My rifle is 1-16 twist. Seems to stabilize anything I put down it.

I talked with Dennis about what happened and he told me it was the wrong bullet to try. I get pretty good long range accuracy with the 250's.

Pretty sure i have the same rifle as you. Ruger Go Wild American? Ive never used a case checker, i use the Lee dies and never had a round that didn't fit/feed/fire just fine. 200 rounds so far. With the exception of when i load a round then put in a loaded 3 round mag, thats when i would get a jam, on the next round.

Yes I love all the cases with hornady 1 shot. Some of the cases fall right in the ammo checker beautiful and some stop short. I wipe them off and resize and same thing.

what is final trim length after sizing

I haven’t trimmed yet but my brass measure 1.690-1.693

I had a Remington 700 built with a 21” shillen select 16 twist barrel.

For some reason I thought you had the ruger, which also has a 1:16”.

 

[Omidv]

Here’s my rifle. 700 action trued, ptg fluted bolt with ar extractor. Shillen select 1-16 twist barrel. Grayboe stock pillars and glass bedded. Hspresicion bottom metal. Timney elite trigger and Leupold VXR 3-9x50 ballistic firedot.

Here's the one I shoot. I just don't shoot it very often. Probably been maybe 3yrs.

HS Precision, Lothar Walther 1:24, Leupold VX6. It had a Timney trigger but now its a Jewell.

have you measured the diameter of case at just before the rim, one to two thousandth will keep it from chambering

should be at 1.695 for case length and seating depth of bullet

Very nice rifle, it deserves to be shot more lol

I measured length many times and yes I’m at 1.695-1.692” I haven’t measured the barrel by the case head though. I should go do that.

 

[Omidv]

Ok I measured near the base and I’m getting.499-.500 doesn’t make any sense

Curiosity ............
I measured 5 of mine. At the head they measured .4970".
I measured right below the base of the bullet at .4855"

Without going back and reading everything, have you tried loading the full length sized cases only?

Yes that’s all I have does for is full length. I’m going to get some rcbs dies and try them while my die is being sent back to hornady.

I just watched a you tube video in which the guy had the EXACT SAME ISSUE, the only difference was he was loading 350 legend. He could not figure out the issue. It turned out that the problem was the Lee die. He switched to a RCBS die problem gone.

 

[michiganmuzzy]

Seems like i hear of more issues, loading the 350, than the 450. Im getting ready to start loading some 350 for a friend. I borrowed a die set from my (best neighbor in the world) neighbor who said he also had a few problems. Ill be watching for trouble.
