Thank you for the review of the competition model. I’ve searched online and YouTube for months and it’s like no one is talking about it. I love my carbon fiber barreled MPR but am looking to pick up this model for PRS style matches.
Took my 6.5 MPR out for another run of reloads. This time using 41.3 grains of H4350, 140 gr Hornady ELD match, CCI #200 primers and once fired Hornady brass. 5 rounds, shot about 20 seconds apart one after the other:
I still can’t believe another company hasn’t bought out his design, patents if he had them, etc to keep bottom metal going. And not just for FN/Winchesters. He made bottom metal for a lot of bolt action rifles.
I put the M*Carbo spring in my A3G and got it down to 1.5 lb. Did the drop test about 30 times, including a couple times where I was worried I would hurt the rifle from hitting the buttstock against the ground so hard. It never went off. Zero issues.
I’m in your same boat OP. I have probably 1,000 once fired factory Hornday brass and just got into reloading in the last 6 months. My view is I’d rather “learn from my mistakes” on the cheap brass I already own before I upgrade to Lapua. But as you can see from the two pics above, my Hornday...
I haven’t tried 10 shot groups yet. I’ve only reloaded about 80 rounds total so far. Next step is a repeat of the same 5 rounds of each at 200 yards, then a selection of which grain amount I want to pursue further. Once I’ve selected my preferred powder load I’ll start to play with jump distance...
Just started reloading for the first time ever. After running up a ladder test from min to a little over max I settled on the 41.3-41.7 gr of H4350 under 140 ELD’s to focus on. With my MPR sporting an SDN-6 I got the following 5 shot groups from testing in .1 grain increases: With the best 5...
Speaking of pressure signs. I did shoot some factory Hornady 6.5 Creedmoor ammo just to check factory velocity vs my reloads. Is the circle mark over the 6.5 and C in Creedmoor a pressure sign? Like an extractor mark? This was on a factory Hornday round
I should also add I had no pressure signs in any of the rounds. No flattened primers, no cracks, no difficulty raising the bolt handle. Even with the 140 ELD’s that I went over max a bit in .1 increments and the 178 ELD’s that were compressed loads at the two highest grain rounds.
The interesting thing to me is the much sharper dips in FPS the 178 ELD’s had vs the 175 SMK at different points. Which doesn’t have as many obvious “nodes”. So my question is this. Now that I can see the points where the FPS flattens or dips despite the powder grains being increased. Is it as...
