Thread: 7mm PRC

Just wondering if anyone has started loading for one yet, and what powder works best other than RL26
Cheers

If Re26 works well and the case capacity is similar to a rem mag, then 2217 and 2225 are gonna be the primary picks.

Yeah I'm hoping 2217 will work as it's cheap and usually available

According to hornadys data h1000/2217 & h4831sc/2213sc arent far behind rl26 in velocity with the 175gr ELDX. 2217 is pretty easy to find at the moment & i have some 2213sc here if you wanted to try that.

Awesome thanks for the offer I'll try 2217 first as I'm thinking that should be the go.
I know RL 26 is probably the best but I want a powder that is always available and won't cost an arm or a leg

My 7 blaser mag went incredible with 2225

Could be worth a try

Hawkins precision and longe range only have a fairly extensive write up and YouTube video regularising powder work ups and what they used to get best results so far

@25/08 IMP for what its worth, GRT suggests that 2217 is only 15fps slower than RL26 with a max charge of both. 2217 would be reasonably compressed at that, RL26 wont be. 2225 gives a little more speed again, but getting pretty compressed. Im going to try RL26 & 2225 so will see what the real world results are but thats what GRT suggests.

Bugger thats the first time iv heard grt come out wrong

I’ve played around with 2217,2225, RL25 & 26 in a variety of 7mms - 280ai, 284, SAUM, RM, BM… RL26 consistently gives 50-70fps gain over the others.

2217 is very temp insensitive, which could be a factor worth considering. The other is that it’s much easier to find than RE26.

Bumping this thread, what are people using in the 7 prc? I have a 22” trueflite arriving next week hopefully.

175s, adg brass, 2217 and 2225 on hand. Would like to try 2217 first so what are peoples speeds and loads

2217 and 2225

About 34 grains of each?
