Comparison: Gator vs. Hornady 30 & 35 cal checks

Postby mtngun » Thu Feb 21, 2008 7:15 pm

30 Caliber Checks:
Gator 4.4 gr vs. Hornady 4.5 gr.
Gator 0.017" thick vs. 0.0167" Hornady
Gator 0.073" tall vs. 0.080" Hornady
Gator 0.281" ID vs. 0.284" Hornady

The Gator 30's have a slightly smaller ID than the Hornady. I tried both brands on a particular 30 caliber bullet. Both went on easily and resisted coming off (thanks to the stepped shank). However, I could spin the Hornady, but could not spin the Gator. Hence, the Gator might fit slightly better on undersize shanks, while the Hornady might be easier to install on oversize shanks.

35 Caliber Checks:
Gator 3.4 gr. vs. Hornady 3.3 gr.
Gator 0.0093" thick vs. Hornady 0.0097"
Gator 0.073" tall vs. Hornady 0.062"
Gator 0.343" ID vs. Hornady 0.342" - 0.343"

Both 35 checks are unusually thin, compared to other calibers. If I were in charge of making gas checks, I would use a thicker material on the 35's. A thicker check would crimp on tighter. However, no one asked for my opinion.:cry:

Update: after all these years, I finally had the chance to actually use those 35 caliber Gator checks. It turns out that, even though I can't detect much difference in the dimensions, the Gator fits looser than the Hornady.

A shank that fits the Hornady perfectly is loose on the Gator. This doesn't seem to affect how it shoots, since the shank will obturate when the round is fired. But it is annoying at the reloading bench. :?

Sooooo ...... I'm going to add a seperate shank option for the 35 Gator check. For the time being, we'll make it 0.3425" rather than the usual 0.3415", though I may tweak the diameter after I've had a chance to work with it.

After working with the 30 caliber Gator checks a little more, I decided to add a special shank for the Gator 30. It'll be 0.2830".

0.2825" - 0.2830" seems to be an easy but adaquate fit, while 0.2835" is quite snug with the Gator 30.

By no means have I measured to the extent you have . And the only calibers I've tried both Hornady and Gater have been in the 44 and 458 calibers . Matter of fact I've even used the Lyman checks on both which I've been told were actually made by Hornady for Lyman in later years .

Anyway in my leveractions on paper I never did see any difference accuracy wise .

Likewise. As long as there is enough pressure to obturate the shank, which is usually the case, then obturation will ensure that the check fits snugly.

The more serious concern is a check that fits too tightly, causing it to shave lead or sit cockeyed.
