Home Forums Hunting & Shooting Ask The Gunwriters 22-300 AYE or 22-300 Weatherby

I just found myself wondering, then laughing at the thought, of how a big case full of Trailboss would work.

Biggest, baddest 22 hornet on the block?

The biggest 22cal I ever tinkered with was a 22-284, your 22-300AYE is well beyond that. I would suggest trying the 55gr NBT it seemed to hold up the best to extreme velocity. For powder I was using H1000 and VVN170, you might have to try something like H50BMG.

In the end it wont matter for too long that barrel will be toast after a couple hundred rounds(probably sooner). It is very close to the infamous Eargensplitzen Loudenboomer !!!!!!!!!!!!! I believe that was a 22-378 Weatherby

boatanchor,thanks for the info. I may pick up some of the 55's to try also as I can use the extras in other rifles I have.

H1000 is what I have on hand, years ago one of the RCBS guys also mentioned one of the 50BMG's.

45 gr TSX might be your huckleberry.

6.5 Creedless?

Who has quickload and wants to chime in with data for bullets that will stabilize in a 1:14? I'm digging the extreme aspect of this whole thing. Seems like 5k is doable with the right bullets and powder. For 25-50 shots, anyway. Then you could get it bored out to a 6.5, and Grandpa would smile down from Heaven a second time, since he loved his 264!

Yeah, I would probably try 40 and 50 grain ballistic tips first. I've had issues with 55s in 1-14 inch .22s. (Have you verified that it really is a 1-14" twist and not 1-16" or slower?) Another light bullet that seems to hold up to very high speed is Sierra's 40 grain HP.

Sounds pretty cool .. an interesting project for a serious gun geek to experiment with.

Maybe rebore to 6mm and go to the TTSX 80gr? Twist it at 1/8 or so? Be a freakin screamer and cut like its on a dremmel.

This right here. Rebore to keep it as original as you can. 6.5-300WBY would even be available as factory ammo.

Fun dilemma. The 6.5x300 would be the easy solution after you get your kicks with the 40 to 50 22 caliber pills. I would say Grandpa was a wildcatter and a suitable country song should be composed in his honor. Best to you.

The original X at 45 grains was a no.Berger says the tsx in that weight won't work because of bullet length. Trimming the bullet from the nose as mentioned above might work.

This is the exact plan. I have a new 6.5-300 Weatherby being worked up now so I would have loading components that would cross over and two burner rifles.

Yeah, I did the cleaning rod spin test on it a couple times.

For sure it is all fun. I have gotten some good information that was not around the first time I tried this gun out. Grandpa would have liked the magneto speed.

Cool. I was thinking back a couple decades to Rick Jamison's .22x.240 Weatherby. I believe it was a 1-16" twist and he shot 50 grain ballistic tips in it.

I'm not a huge fan of the 55 grain ballistic tip. I've had at least a half dozen 1-14" twist .22-250s and .220 Swifts and of all of them, only one would stabilize the 55, the rest were minute of bucket. Drop to 50s ... half MOA. So now I always start with the 50 to prove accuracy is possible before I try the 55s.

... just a thought. Good luck whatever you wind up doing with it.
