I'm a little new to reloading. I picked up some Rainier .45 200 gr flat nose. Rainier's site says load to lead specs. Problem I have is the rounds don't feed. Is this a powder problem or OAL problem. I loaded them with 5.1 grains Unique at 1.19 OAL. I am also shooting an EAA Witness Elite. The gun handles a 200 gr lead swc with the same powder with no problem.

Sometimes a weaker load will not have enough recoil to cycle the action in certain guns but it seems that if the same charge is enough to cycle the gun's action with your SWC bullets, it ought to be enough with any bullet of the same weight.

Some guns just don't like some bullet shapes when it comes to feeding. Sometimes it can be fixed by adjusting the OAL and sometimes not. Just be careful in adjusting the OAL if you try seating the bullet deeper into the case. This will raise your pressures. If I was anywhere close to a max charge, I'd back off as part of experimenting with a shorter OAL.

Hello Kirk, Welcome to the forum. The Witness Elite has a heavy slide mass and you need to have rounds produce enough energy to cycle that mass and recoil spring rate.

The 5.1 grain load of Unique @ 810 fps is on the light side and is said to produce only 9,600 psi with the 200 SWC (Target Load) the recoil springs would need to be on the lighter side for that load)

Whereas the 200 JHP is shown using 7.1 grains of Unique @ 975 fps produces 19,500 psi and is closer to the operating pressure of the 45ACP pistols.

With the plated bullets (like lead alloy) you need to take care to seat the bullet so that no shaving of the plating occurs. Many seat in one step without any crimp being applied and then in a separate step do the final crimp...this provides better uniformity and better feeding overall! The plated bullets work well up to about 1100 fps but driving them too fast is not good, the 45ACP ballistics should not present that problem.

If you are wanting target loads try bumping up the charge weight to 5.4 grains, and if you want more velocity or power I'd go to 6.0 grains to see how the gun works.

Best regards!

Feed problem will be OAL issue.

I find with 200 gr LSWC they need to be seater deeper
and 200 gr flatnose bullets need to be seated out a
little more. May take some trial and error to find
the sweet spot, with those flatnosed bullets.

Found some Rainer data using Accurate powder.

It was using this exact same bullet that taught me the process of experimenting with OAL to ensure positive feeding.

Start with an empty shell and seat the bullet out as far as it will fit in the magazine and test feed the round by riding your hand on the slide (which you should not do in real life). By progressively seating the bullet deeper, you will find the point where it feeds the smoothest.

For me, I wound up with a longer OAL to get reliable feeding. if for some reason yours winds up shorter, be sure to adjust the powder charge lower accordingly.

Thanks for all the info. I guess it's going to take some trial and error with them. If I ever get it worked out in a timely manner I'll post the results.
