Western Airguns All Things Western Rattler 357 & 45 - Master Thread

The Western Rattler in 357 & 45 caliber's master thread (inspired by @Ezana4CE) for the owner's and prospective owner's to compile, read, and search for good information on the Western Rattler big bore. Please contribute what information you have learned, read, videoed, or viewed down below, albeit maintenance, pictures, settings, slug accuracy, FPS and PFE, scope and hunting setup, hunts, etc...

Link to micro polishing the magazine and adjusting the barrel for smoother operation:

 
The Rattler 45 barrel diameter is 0.685" and the muzzle threads are M17-1 for reference to putting on a muzzle brake. An experiment with a thick carbon sleeve 24.25" to maintain barrel tension and muzzle brake with M17-1 threads is in order... I put a modified tanker style muzzle brake on an AEA Challenger Bullpup 457 and it was shown to have noticably less recoil (nearly none on the big heavy beast) and no discernable barrel whip.

Long Strike range testing with a variety of ammo for accuracy today. The light ammo looked like a shotgun pattern, waisting air and lead. The groups tightened up as the slug length and weight went up. The best slug as predicted was the NSA .454 350 grain HP-RBT slugs that I had cut down to fit the magazine. (.998" long and 353 grains).

I had some pretty tight groups from 100 and 175 yards going with these heavy NSA slugs, so with the last 4 slugs I had I dialed to 235 yards to check accuracy at that range. After a sighter and scope adjustment I was working on an moa group but then I threw the last shot about 6" with a big assed flinch. (Still getting used to this mechanical semi auto big bore I guess...)

All in all it was a good day. The trigger is a little gritty feeling and something needs attention/lube/polishing there.

I am seriously considering getting a long strike 45. Curious about optimal diameter for accuracy. Doesn't surprise me that longer slugs seem to work better, my K1s are the same way. I already make .46 slugs for my challenger bullpup, and have a sizer to make them .457 for my don cothran. I've already checked with corbin that I could get a size reducer that will take them from .46 to .452 in one step, but hoping I can learn what is optimal from others before pulling the trigger on a reducer size. I'd be willing to send some of my .457 slugs to a long strike owner for testing too

@Asher Tristan of Atlas Airguns did a good job of addressing Rattler .45 slug diameter here https://community.hardairmagazine.com/threads/rattler-45-long-strike-review-50-100yd-more.2867/

I've noticed this trend with my 357 rattler. I have 1 short slug that shoots well, the rest are long bois. Have a hunch about why...

The magazine isn't going to align to the barrel perfectly every time. The slug will jump out of the mag and into the rifling imperfectly every time, leading to the slug being off centerline and with a different yaw. These imperfections show on target. Longer slugs have a longer patch of lead engaging the rifling which may allow it to self-align better than those with a shorter engagement.

I figure it doesn't matter how long the slug happens to be... what really matters is how long is the prtion of the alug in contact with the rifling (the bourrelet length). My testing has shown this to be at least partially true.
