Re: Recent reloading findings and data

Well, I've been doing a heck of a lot a of shooting lately (and cleaning of rifles) but that's how you get to know em and subsequently get bullets on hide when it counts. Maybe some will find it interesting I sure have. Big smile

Re: Recent reloading findings and data

I have been working with H414 in my 243 with 75gr Hornady HP's and V-Max. Got the P's because for quite a while I couldn't find V-Max's. Also got the H414 because powder was also hard to find so when an 8# jug showed up, I bought it. Fooled first with 70gr SMK's and standard primers, groups just over 1/2" were common. Then tried magnum primers and it cut the group's by about half! Went back with the mag primer's and the 75gr HP's and getting just under 1/2". Of course I also did some more bedding work on the rifle. It's a 700 ADL with el cheapo plastic factory stock. I completely dug it out and freeded up everything then re-bedded the action at the recoil lug and the rear tang. There was up lift in the barrel and that I took out and the barrel is floated from the recoil lug forward. The recoil lug is up against the stock where it belongs and the bottom and sides were relieved. That stock was so tight every where it didn't want to come out when new. The other night I took it apart again and bedded the side's of the action where the front trigger guard screw goes in. Always figured that had to stress the action. In the rear tang and the front action screw I cut piller's from 3/8th copper tubing and glued them in. Once in I added more bedding to be sure the pillars were even with the bedding. The rifle came with a plastic trigger guard and after putting in the pillars, I got the rear tang screw to tight and it thing split and wouldn't tighten down the action. Ordered a new steel trigger guarg from Midway and installed it. The trigger I took down to right at 3# and I put a 3-9X Nickon Buckmaster on it.

To much work to still have that junk stock but, it does shoot now! Going to go up and cronograph the load with H414 tomorrow or the next day. The old load with the 75gr V-Max, IMR 4350 and standard primer's cronogrsaphed out at 3150fps. Going to look for 3300fps maybe a bit more with H414. Have taken it all the way to max in my Hodgdons manual but backed off a grain it shot a lot better, three shots under 1/2". This has been my first time ever trying H414 and I'm impressed! Works best for me with mag primers, Fed to be exact. Now if I can just find a sourse for them, gettin low!

Re: Recent reloading findings and data

Good info on the H414, I'll have to see if I can get some and give it a try and better my accuracy. Going to try and get out one day this week and do some coyote and prairie dog zapping. I'd like to see the terminal ballistics for these 70 gr ballistic tips.

Thanks!

Re: Recent reloading findings and data

JJD, thanks for the recipe, I may have to give that a try.

Well, I picked up some 162 gr Hornady Interlocks for the 7 mag since they had em in one of the local gunshops. From my research I wouldn't use an interlock for elk due to the possibilty of frangibility. I know some guys use them with great success on elk but I'd rather have a bonded bullet. Anyway, I picked em because of the price and they were there and their pretty similar to the Interbond in shape so I figured if they shot well I'd pick up the Interbonds to try next. I used Federal brass from some premium factory ammo I used a few seasons ago. I shot up from the lowest to hottest load with RL-22 (max load 63 grains) using CCI Mag primers with the bullet seated just off the lands at a COL of 3.30. They were giving me consistent 1 to 1 and 1/2 inch groups at a 100 so I took the target out to 300 yards. At a hundred I had it sighted in 2 inches high and there was a semi stiff (around 12 to fifteen mph) breeze from right to left. I shot three groups the best being slighty over an inch and the other two at 1 and 1/2 inch and two inches. I'm damn happy with that and will now get some Interbonds to see if they shoot as well. If so, that will be my Elk load for my bull tag if drawn. I'll still use my 30-06 probably for a pp left over cow tag I plan on getting if possible. The book lists this max load traveling at 3000 ft per second. Any of you guys familiar with the 7 mag tell me what you think of a 162 gr bonded bullet such as the Interbond or Accubond for elk medicine. I know some guys prefer the 175 gr but I've heard good things about the 162 and the 7 mag as well. A good blend of weight and BC.

Heres the best 300 yard group:

Re: Recent reloading findings and data

I was mistaken in that I thought Hornady made the Interbond in a 162 gr. I do plan on trying the Interbond for the 7 Mag but it will have to be the 154 gr. Again, anyone who's used these on elk I'd like to hear from em. The other consideration would be the 160 gr Accubond. That 154 should be very flat shooting!

Re: Recent reloading findings and data

I had no luck with the Accubonds in my 700 BDL 300 win mag.
Just could not get them sub MOA no matter what I tried.

Yeah JJD, that can be damn frustrating especially when you drop a pretty penny on em. The 7 Mag rounds I've been shooting are from once fired (someone elses gun) Federal Brass I purchased from my gunsmith. I full length resized em and made up my rounds. Now that I'm getting serious about the 7 mag for elk this year I'm going to buy some virgin Winchester brass, some more RL 22 in addition to the IMR 4831 I have on hand and some 154 gr Interbonds and try and get me my definite elk load. I'm going with the Interbond first because I believe they and the Accubonds are pretty similar in elk killing ability, quality, and construction. But, you get 100 Interbond bullets for the same price you get 50 Accubonds roughly. If I can't get em to shoot I'll try the 160 Accubonds next. If they shoot like those Interlocks I'm set.

Went shooting yesterday with my dad who was shooting his Marlin XL7 in 270 cal and some 140 gr Accubonds he cooked up. His first lowest load gave him an almost one hole 3 shot group. His max load was giving him 1 inch consistent groups and we then took it out to 300 hundred yards and his two groups were 2 and 2 1/2 inches. We've been shooting at 300 yards every time out lately and It's a great confidence booster to know where your gun is hitting at those ranges. I also will put pop cans out from 150 to 250 yards and shoot em. Once your dialed in knowing rise and fall of the bullet path at different ranges your good to go.

Well, be taking the targets out to four hundreds next times out. 400 yards is my limit when it comes to extended shooting ranges, I think that's a good blend between marksman ship skills and hunting skills although I'll always try to get closer first if possible. I've been shooting at least once or twice every couple of weeks for the past year and it really has boosted my shooting skills and confidence. I remember when I was a kid and we'd shoot only once at the range to sight in right before the season. I was always afraid I'd only get a shot at 200 or further and worried I wouldn't be able to get it done.

Those days are long gone. Big smile

Re: Recent reloading findings and data

My son in law has had some pretty good results with IMR 4350 in his 7mm mag
Browning A-Bolt w/Boss
Nosler partition, but I will have to ask him what the exact recipe is.

Re: Recent reloading findings and data

Don't seel the 162gr Interloch short. It's heavy enought to hold together in the 7mm mag. I'd bought 140gr Nosler Part's to hunt with in my 6.5x06 and broke it in with 140gr Interlocks. Still have never killed any animal with a Partition but have killed two elk with two shot's with that 140gr Interlock.
