75mm Pros Vs. Cons of Aero-Tech vs. CTI

[mtnmanak]

Does anyone know of a similar crossload matrix for using CTI reloads in AT hardware?

CTI provides this info for 75mm and 98mm:

Cross reference as to which RMS� case is to be used with which CTI� reload

Pro75-2G = RMS75/2560

Pro75-3G = RMS75/3840

Pro75-4G = RMS75/5120

Pro75-5G = RMS75/6400

Pro75-6G = RMS75/7680



Pro98-1G = RMS98/2560

Pro98-2G = RMS98/5120

Pro98-3G = RMS98/7680

Pro98-4G = RMS98/10240

Pro98-6G = RMS98/15360

Does that mean I can use any of those loads in the compatible RMS hardware? Also, what about 38mm and 54mm reloads? Are they compatible? There is no mention of crossloading 38mm or 54mm from either Aerotech or CTI.

AT has been very open about using their reloads in CTI hardware and their recommendations (which do include using the forward seal disc).

That's interesting and very useful, but what I've been posting about is the opposite, using CTI reloads in AT hardware.

The exact certification status of crossloads has been argued a lot over the years on this forum. Some say that every particular combination has to be explicitly tested, some say if it fits it's OK to use because the hardware is compatible. I've never heard any official statement about this.

Sizes 54mm and below have never been compatible. See http://pro38.com/faqs.php for the history of how 75mm and 98mm crossloads came to be (from CTI's perspective at least.)

Nope. Only 75 and 98 are cross compatible.

Thanks for the replies - I figured 38mm & 54mm weren't compatible since they are never mentioned. Good to have the info straight from CTI - not sure how I missed that in their FAQ!

AT's own crossroad matrix states 75mm 5g and 6g AT loads are not certified in a CTI case. If you make them work then it is considered EX.

The grain spacer o-rings are only for ease of ignition. I would have no problem leaving them out . I would definitely use the Aerotech forward seal disk. The disk orings usually survive, you could probably reuse them if needed.
