Hello,

I have a few questions on trimming and long range shooting. I have an RPR in 300 PRC. I’m using Peterson brass, H1000 with Berger 220g hybrids. I’m very happy with results at 100 yards, but the new brass is a tad long and I’d like to trim it to the length of the current lot I have. The issue is the trimmer I’m using is the “ugly trimmer” and it’s not consistent, like 5-6k variance. I have the Lyman Xpress trimmer, but the collet for 300 PRC has been on back order since Jesus was here. So I’m looking for an affordable replacement until the collet is in stock. I called Lyman and they said July, but that was 3 months ago, and with everything going on I’m sure that time frame will get pushed back again (I was told April in January). Peterson brass in 300 PRC isn’t exactly cheap, so I’d appreciate any suggestions on a temporary trimmer that’s not pilot driven (as it marks up the inside of the neck). Also one that’s not going to break the bank. I don’t mind putting in the work, but I need consistency, and prefer one that’s adjustable. Also, I don’t mind selling my Lyman if there’s a good universal one that will do multiple calibers that’s consistent. My budget isn’t super high, but I’m willing to consider a more expensive one if it’s very consistent.
 

Not adjustable, bu still the cheapest way to fly. Slightly manual intensive, but all the cases will end up the same length with case necks square to the case head.
 

Slightly more expensive but has some adjustment in it.

Both options are viable on a temporary basis.
 
Probably more than you are wanting to spend. I know manual trimmers are not popular but an LE Wilson will set you back about $180 for just the trimmer and shell holder. No micrometer adjustment, and no stand. So you would need to affix it to something, and work your way shorter measuring each time. On a plus side, you can get an adapter to run it with a small drill or electric driver. Little better than the crank handle. I use the full kit ($275), but I only reload a few hundred a month so it's not that big a deal to me.


So if anything, you could leave it setup for just your 300 PRC.
